Fluorocarbon vs Monofilament Fishing Line Diameter with Charts

Fluorocarbon and monofilament fishing lines have very similar diameters but the line thickness does vary depending on the type and brand of line. In this article, I will compare lines from the same company that make fluorocarbon and monofilament. Ande, Berkely Pro Speck, and Seagaur Blue Label are fluorocarbon leaders while Trilene, Berkely Vanish, and Seagaur Red Label are all fluorocarbon lines.

Fluorocarbon and monofilament spools
There are other line property differences between fluoro and mono as well. A fluorocarbon line is more dense which means it sinks faster in the water while nylon monofilament sinks slowly or even floats if surface tension is holding it on the surface. The index of refraction of water is 1.33, fluorocarbon is 1.42, and monofilament is 1.55. Since the fluorocarbon line index of refraction is closer to water it will bend light less making it less visible underwater. Sometimes fishing lines are transparent underwater and sometimes the line can be easily seen. It depends on the color of the water and lighting conditions. The thickness of the line is a major factor in line visibility. A significantly thinner monofilament line will be less visible than a thick fluorocarbon line.

In general fluorocarbon line is slightly more abrasion-resistant but it is very similar to a monofilament line if the diameter of the line is exactly the same. A fluorocarbon line is made with fluorine and carbon atoms. This chemistry makes it so the line is UV resistant and does not absorb water. A monofilament line breaks down over time with light exposure and will weaken over time when it absorbs water. For this reason, the monofilament line is typically only good for one season and then should be replaced.

Ande makes both fluorocarbon leader line and monofilament mainline. That is what this chart is comparing. Which line has a smaller diameter depends on which pound test is being compared. These lines have a similar diameter at most line strengths. Ande line diameters are comparable to most other lines except at the 80-pound test strength where the diameter is larger than most other lines. I really like using Ande fishing lines and the lines have great overall performance.

Both ProSpec and Berkley Trilene Big Game have large line diameters compared to other lines. ProSpec is one of the thickest fluorocarbon leaders on the market and has a larger diameter than Trilene Big Game at every pound test. This does mean that both lines will be abrasion-resistant and overall strong lines for their given weight rating. If you are looking for a thin transparent line for leader shy fish there are better options. These lines are both made by Berkley which makes them a good comparison for the different line types.

Berkley Trilene makes both fluoro and mono lines and these have the same line diameters. This shows how similar the two-line types can be even though they are made with different materials. These lines will only vary slightly in their properties and performance. I like using Trilene XL on spinning reels as it is soft and good for casting.

The fluorocarbon line is labeled as more abrasion resistant and likely a bit more transparent underwater. It will also sink faster which can be an advantage when bass fishing with light soft plastics. When fishing in water over 3 feet deep soft plastics sink too slowly which wastes time as you wait for them to get near the bottom. Adding weights makes the bait look less natural. The 100 percent Fluorcabon line will last longer cause it is much less susceptible to UV damage and the line will not absorb water.

Berkley Vanish and Berkely Trilene XL are a good comparison as these are both used as thin light lines for spinning reels and baitcasting reels. Comparing the line thickness the Berkley Vanish has the same or smaller line diameter than the Berkely Trilene XL. This means the fluorocarbon line likely will be less visible to the fish. Berkley Vanish lines under 10 pounds are thin and flexible which is why I like using them when trout or crappie fishing. When bass fishing the Berkely Trilene XL is perfect in the 10-17 pound test.

This chart compares Seaguar Blue Label which is a fluorocarbon leader line to Seaguar Red Label which is a fluorocarbon mainline. Surprisingly the leader line has a thinner or equal line diameter to the main line. These lines are both 100 percent fluorocarbon so the difference is how they are manufactured. Many people are starting to realize that using fluorocarbon mainline as the leader line is a way to save money and get a very similar line performance.

Fluorocarbon and Monofilament Line Stretch and Flexibility

The monofilament line has higher line stretch which helps prevent the line from breaking from sharp increases in force. This is why mono leaders are used for shock leaders when fishing with braid as the mainline. The monofilament line is also softer and more flexible which makes it better for casting. Fluorocarbon line has made improvements in this area and a fluorocarbon line is softer and more flexible than fluorocarbon leader material. For this reason, Seaguar Red Label, Berkely Vanish, and Trilene Fluorocarbon all work well as a mainline for test values under 20 pounds. This is because the line is thin and light enough to cast well.

Fluorocabon, Monofilament, and Braid Line Sensitivity

Fluorocarbon is slightly more sensitive than the monofilament line when it is under tension. These lines are about equal when not under tension. A braided line is static and is actually most sensitive when there is a load. However, it does not provide any feedback when the line is slack. A slackline providing feedback is actually important when letting lures and bait sink. A slight thump on the line can let the angler know he needs to bring tension to the line to set the hook. This helps the fish from getting hooked deep where it is hard to remove the hook.

IGFA Fishing Lines

Many times the world record fish are recorded based on the strength of the fishing line. This means the strength of the mainline and leader material. While some lines claim to be IGFA rated the line still needs to be independently tested after the catch is made. This is done by sending in 5 meters of the line closest to the hook to be tested. For this reason, it is important that a fishing line company not under-report the line strength. There is some flexibility in line strength because the classes are given in terms of kg. For example, the 10 kg class allows lines up to 22.04 pounds.

If you plan to fish for an IGFA record fish testing the line strength before going fishing is a good idea. The record will still count as a world record fish if it is still the largest fish caught in the next line class, assuming the other requirements are met as well.  The exact type of line does not matter and it can be braid, monofilament, or fluorocarbon. The weight of the fish does have to be 50 percent or heavier compared to the class of line. Most anglers just want the line not to break so they are happy if the line is stronger than the listed values.

You can catch a fish that weighs more than the pound strength of the line if the fish is not lifted out of the water. This is because fish are about the same density as water so can slowly bring a heavy fish to the surface even with a light line. For example, my nephew caught a 30-plus-pound nurse shark with a 10-pound fishing line.

Fluorocabon vs Monofilament Lifespan

A fluorocarbon line has a shelf life of 5-8 years, monofilament has a shelf life of 2-3 years, and a braided line has a self-life up to 10 years. When actually being used on fishing reels the line will not last nearly as long. Braid still lasts the longest, followed by fluorocarbon, and then monofilament. A braided line can last up to 5 years even when being used. Most monofilaments only last a few months of use and breakdown due to UV damage and water absorption.

None of these fishing lines are biodegradable. This means that anglers should do everything they can to make sure the line does not end up in the water. Everyone gets snagged on the bottom from time to time. However, knots are not as strong as the mainline so very little gear and tackle should ever be left in the water. I use to work on scuba diving boats and we always tried to remove any fishing line we found from the ocean.

Fluorocarbon and Monofilament Abrasion Resistance

There are some tests that show a fluorocarbon line is more abrasion resistant and some tests show a monofilament line is more abrasion-resistant. The truth is that each type of fishing line has slightly different properties.

The video above compares lines that are all 100 percent fluorocarbon and the lines still have very different abrasion resistance values. This could be due to a large number of factors. Even though the lines are the same pound test the diameters are slightly different. The manufacture date and storage conditions could also have been different.

Typically I do not have lines that break due to abrasion issues so this is not super important. I will make sure that I use a mono, fluoro, or steel leader rather that a braided line. If you have an issue with tarpon, snook, or billfish wearing through a certain type of line then it would be a good idea to change line type or increase the leader strength. If the line is rubbing on the bottom or rough objects then it is a good idea to remove that line as all types of fishing lines decreased in strength over time due to abrasion.

Types of Fishing Line: Monofilament, Braid, Fluorocarbon, Specialty Lines

The three main types of fishing lines are monofilament, braid, and fluorocarbon. There are also fishing leader lines made out of monofilament, fluorocarbon, single strand wire, and multi-strand cable. The color of the fishing line can also be important to be less visible to the fish or more visible to the angler above water.

Lead core, Monel, copper, and stainless steel wire lines allow lines to sink deeper into the water when trolling with lures and spoons. There are four types of fishing lines used for fly fishing which include a backing line, floating line, tapered leader, and tippet. When ice fishing there is a specially designed braid to reduce ice buildup on the line.

Summary of Fishing Line Types

Braided Line: Ultra-thin, strong lines with no stretch, offering superior sensitivity, casting distance, and line capacity on reels.

Metered Braided Line: Color-changing braided lines that mark depth increments, providing a visual reference for precisely controlling trolling depths and distances.

Monofilament Line: Single-strand nylon lines with good stretch and versatility, ideal for many fishing situations from freshwater trout to offshore trolling.

High Visibility Line: Brightly colored lines designed for maximum visibility above water, helping anglers detect subtle bites and prevent tangles when running multiple lines.

Fluorocarbon Fishing Line: Low-visibility mainline that sinks faster than mono and is more transparent underwater. This is best used in a lighter-pound test as it gets stiff with thicker lines.

Fluorocarbon Leader Line: Less visible underwater and has superior abrasion resistance, perfect for leader applications with leader-shy fish.

Multi-strand Cable Leader Line: Flexible steel cables resistant to kinking, primarily used for shark fishing and trolling for toothy species.

Single-strand Wire Leader Line: Thin, strong steel leaders that provide protection against sharp-toothed predators while maintaining better visibility than cable.

Fly Fishing Line: Braided backing line, floating line, tapered leader followed by a a tippet line.

Lead Core Line: Dense, sinking lines with a lead wire center and colored metering system that allows precise depth control when trolling without downriggers.

Monel Line: Premium nickel-copper alloy trolling wire with superior strength, corrosion resistance, and kink resistance for deep water presentations.

Ice Fishing Line: Specialized cold-resistant lines that reduce ice buildup and provide sensitivity in winter conditions.


Braided Fishing Line

Braided fishing line seems to be coming more and more popular. The biggest advantage of braid is that it is thin and light witch allows for far casting with spinning tackle. Since it has a small line diameter fishing reels can hold significantly more line. This allows lighter tackle to be used to catch bigger fish. One of my favorite setups for freshwater fishing is using a 20-pound braided line with a 20-pound fluorocarbon leader. The setup can be cast far and is strong enough to catch pretty much any fish that will bite.

When saltwater fishing I like using a 50-pound braided line on spinning tackle with an appropriately sized leader. This will work great to catch both small and large fish. For trolling reels 80-100 pound braid is a good size. If the line is to thin it can dig into itself. An 80-pound line is strong enough to catch just about every fish in the ocean. It is import to use a reel with quality drag with braid and line that does not stretch to account for sharp increases in force that can happen when fighting large fast fish.

Braided line has virtually zero stretch which makes the line very sensitive to feeling bites. When fishing in deep water or with lines set far behind the boat it also allows for a quick hook set. Braided line does not absorb water which makes the wet and dry knot strength about equal.

Power Pro braid is one of the most widely used fishing lines on the market.  This original Power Pro line is made of spectra. Power Pro has several other variations of braid including Maxcuatro which is 25 percent thinner, downrigger line which is a 200-pound braided line, and ice-tec line designed to limit ice build-up while ice fishing.

The braided fishing line is the best line for spinning reels from a 15-pound test to a 100-pound test. This is because braid is lightweight and flexible which allows for far casting. A braided line has virtually zero stretch which makes it the most sensitive at feeling bites and great for quickly getting a strong hook set. The braided line also has about a seven-year shelf life and can last several years on a reel. Another good thing about braid is that it does not absorb water so the knot strength is maintained when the line is wet. It is also very resistant to damage from UV light.

Moss-Green is the most popular braided line color but white is also a great color to use. The white line has good visibility above water and low visibility when the sky is the background. The least visible braid depends on the lighting conditions and color of the water. The video below shows how different colors of braided lines look above and below the water.


Metered Braided Line

Metered braided line has become one of my favorite fishing innovations in recent years. These specialty lines feature alternating colors that change at specific intervals, typically every 25 feet. Some lines even include 5-foot marking bands within each color section. Using a metered line is a great way to estimate the depth of the lures and the distance of the lures behind the boat.

Power Pro Depth-Hunter is a braided fishing line that is metered. It is made with alternating blue, yellow, green, and orange colors every 25 feet. This means that every time a color repeats 100 feet of the line has been let out. Within each solid color, there is a black tic every 5 feet to further define the depth of the line.

Many angels never think about the benefits of using a metered line. There are other ways to estimate water depth by pulling arm lengths of line or counting so many seconds. In my opinion, outside of using a line counter reel, a metered line is the best way to estimate line depth. However, a metered line can be used on spinning reels and conventional reels without line counters. The metered line is also a good way to estimate the distance lures are behind the boat. For diving plugs, the amount of line set out determines the depth of the lure.

When using a braided fishing line I see little reason for it not to be a metered line. Braid is almost always used with monofilament or fluorocarbon leader so the color of the braid is not important. It is surprising how useful a metered line can be, especially when jigging deep in the water.


Monofilament Fishing Line

Monofilament fishing line is a great type of fishing line to use to catch many types of fish. For freshwater fishing, a light 4-6 pound monofilament is good for trout, crappie, and panfish fishing. When bass fishing 12-20 pound test works well depending on the weight of the lure. When trolling in freshwater 20-30 pound monofilament line is commonly used on conventional fishing reels.

For saltwater fishing spinning reels a 20-pound monofilament is good for reef fishing and a 30-pound line is good for fishing offshore for small tuna and mahi-mahi. When targeting big game fish with convection reels a 60-80 pound line works well for fish up to around 400 pounds. For huge bluefin tuna and marlin, a 130 class reel and 130-pound monofilament line are best.

When selecting a good monofilament, the desired properties are for the line to have stretch, flexibility, and high knot strength. Most monofilament lines will work on conventional reels but soft thin lines should be used on spinning reels. Also, make sure the monofilament line is not old. These lines break down with age and UV light exposure. An old line will have decreased tensile strength and knot strength. After tying a knot always pull hard on the line to make sure the line is strong.

Berkley Trilene XL smooth casting is the best monofilament fishing line for spinning reels. There are several types of Berkley Trilene lines include Big Game, Extra Tough, Fluorocarbon Ice, TransOptic, BigCat, and Sensation. This XL smooth casting is a soft flexible line designed for far casting.

The line is labeled as super strong, maximum manageability. Monofilament line works reasonably well up to about 30 pounds on spinning reels. For line strength above 30 pounds, it is typically best to them switch to a braided line. Fishing with a 20-pound line is strong enough to catch the most freshwater fish. A 30-pound line is strong enough to catch big game fish such as king salmon, tarpon, mahi-mahi, and sailfish.

Sufix Superior is the best fishing line for saltwater fishing. The line can be purchased in bulk for a reasonable cost. A 30-pound line is perfect for saltwater spinning reels and a 60-pound line works well on conventional reels that are used for big game trolling.

The line has high stretch and good knot strength. It also is known for being a good 130-pound class fishing line and is made in line strength up to a 400-pound test. Monofilament line does break down from UV light and has a shelf-life of 2-3 years. When fishing with a monofilament line it is always a good idea to test each knot after trying it and change out the line at the first sign of a weakened line.

Berkley Big Game Trilene is the best monofilament fishing line for freshwater fishing. That line is great for conventional fishing reels used for trolling or jigging. Trilene XL smooth casting monofilament is better for baitcasting reels and spinning reels. This monofilament line has an average thickness to strength ratio.

Big Game Trilene is reasonably soft and flexible so it does not get bird nested easily. The line does have memory so it is good to spool the line onto the reel the night before. The line can also be used for saltwater. It is a very reasonably priced line and the 8-pound to 15-pound Big Game Trilene line does work decently on spinning reels. A 20-pound to 60-pound line works well for conventional reels depending on the type of fish being targeted.

Stren clear blue fluorescent is the best fishing line to use with a black light or fluorescent night. The line will reflect the light and become highly visible to the angler. It is the best line for night fishing in my option because the clear blue line is also a good color for daytime fishing. This makes it so the same reels can be used during the day and at night.

There are several other good monofilament lines to fish with under a black light. These include Stren’s High Impact in high visibility green, Berkley Big Game solar collector, and Berkley Trilene Sensation solar. For a braided line, the best type to use with a blacklight is Super8Slick V2 in the moonshine color.

Ande Premium is the best pink monofilament line on the market. The color red and pink disappears at around 20 feet of water depth. For this reason, many anglers use a pink line when bottom fishing and jigging.

Some people might think even though pink disappears a clear line is already clear so why not use that. The reality is that a blue, green, smoke, or pink-tinted line can be less visible depending on the amount of light, water-color, depth of water, and background color. If people in the local area use a certain color line for a certain fish, chances are there is a good reason.

Sometimes fishermen think that because they occasionally catch fish with a certain setup that details such as line color do not matter. Sure I have caught leader shy fish like tuna and snapper with highly visible wire cable. That does not mean that the fish are not typically leader shy. Chances are that day we got lucky with aggressively feeding fish and lighting conditions that made the line visibility less important. There are other days when switching from a 15-pound fluorocarbon leader to a 10-pound leader will make the difference of catching fish or not catching fish.

Maxima Ultragreen is the best fishing line to use when salmon fishing. This line has a smoke green tint that matches the water-color where salmon are found very well. This line works as a mainline or leader material. For a mainline when salmon trolling 30-pound line is perfect. When making salmon leaders 30-50 pound test is typically used.

If you are not fishing way offshore in clear blue water chances are the water color will be stained green. That makes this a good line choice of line for many types of fish including fluke, striped bass, and bluefish. The line is above average quality monofilament with good knot strength, medium stretch, and average sensitivity.


High Visibility Fishing Line

Bright colored fishing lines are not meant to hide from fish but to be seen by anglers. When running multiple lines while trolling or drift fishing, high-vis lines make it easier to track each line’s position and prevent tangles. They also help detect subtle bites by showing small movements that might otherwise go unnoticed.

For night fishing, special lines that reflect blacklight or UV light glow brightly, solving the challenge of monitoring your line in darkness. Popular colors include yellow, chartreuse, orange, and white for daytime use.

While traditional wisdom suggests keeping lines invisible to fish, when using proper leader material, mainline visibility matters much less than being able to see your line above water. This is why many professional captains prefer high-visibility mainlines paired with appropriate leaders for the target species.

Sufix Superior in high visibility yellow is great for seeing the line above the water. This allows anglers to keep track of lines when drift fishing and trolling to prevent lines from crossing and getting tangled. The line comes in 1/4 pound or 1-pound spoons so the length of the line varies based on the strength rating.

There are several good high visibility monofilament line colors on the market including high visibility yellow, pink, solar green, and blaze orange. Braided line colors that are visible above water include high visibility yellow, white, red, neon lime, and orange. Many anglers select a line based on the underwater visibility of the line. However, if a leader line is being used the color of the line above water can actually be more important.


Fluorocarbon Fishing Line

A fluorocarbon fishing line is technically a type of monofilament line. It is made with a fluorocarbon resin material rather than the typical nylon resin for standard monofilament. The fluorocarbon line is denser and has an index of refraction closer to water than a nylon line. The result is that less light is bent and reflected by the line making it less visible under some conditions. The downside of fluorocarbon is that it can be stiff and less flexible. This makes it a bad mainline to use for spinning reels if the line is over a 10-pound test. When the line is under a 10-pound test it is so thin and flexible that it still casts very well.

The more dense fluorocarbon line does not absorb water like nylon monofilament. This allows the line to have higher abrasion resistance and knot strength when wet. A fluorocarbon line also sinks faster than a monofilament line, which helps get lures deeper and maintain better contact with the bottom.

Berkley Vanish is a fluorocarbon fishing line that is used for the entire spool of line, not just the leader. Typically fluorocarbon is a stiff line that is only used for leader material. This line works well on spinning reels if it is under a 10-pound test. Above 10 pound test it works well on conventional fishing reels. Berkley Vanish is the best line to use in a 2-pound to 6-pound test for trout fishing. Trout can be leader shy and this low-visibility line works very well.

Fluorocarbon has several advantages over a standard nylon monofilament. These advantages include being more sensitive, higher wet knot strength, faster sinking, abrasion-resistant, UV resistant, and lower visibility. Fluorocarbon has an index of refraction of 1.42, monofilament is 1.55, and water is 1.33. Since fluorocarbon has an index of refraction closer to water the light passes through it with less bending and reflection. In certain situations, this can make the line less visible. Fluorocarbon is not invisible to fish and using a thinner fluorocarbon line makes the line less visible.

Since fluorocarbon has an index of refraction closer to water the light passes through it with less bending and reflection. In certain situations, this can make the line less visible.

In most cases, a fluorocarbon line is primarily used as leader material rather than mainline. Remember that fluorocarbon is not invisible to fish and using a thinner fluorocarbon line makes the line less visible. Using a 4-6 pound line is good for crappie and trout. A 20-pound leader is quite strong and is a great size line for a wide range of fish from bass to most types of inshore and reef fish. When targeting large fish 50-100 pound leaders are typically used. Line up to around 80 pounds can be tied with knots rather than crimps.

Fluorocarbon leaders are especially important when fishing for leader-shy fish like bonefish, permit, snapper, and tuna. The line can be damaged from the bill of billfish or the rough mouths of tarpon. Once a billfish is caught the leader line should be changed. The line could be damaged and more often the bill rubbing on the line makes surface scratches on the fluorocarbon leader which makes the line very visible. Anytime fluorocarbon lines get scratched the leader section should be changed.

Seaguar Blue Label fluorocarbon is a very popular fluorocarbon leader from a 10-pound test to a 220-pound test. This is the best big game offshore fluorocarbon. It is a 100 percent double structure fluorocarbon. The advantages of this line is low-visibility, high knot strength, abrasion-resistant, and fast sinking.

A heavy abrasion resistant leader line is especially important when fishing for billfish. The bill of the fish rubs on the line and can wear through thin monofilament fishing lines. Once a billfish is caught the leader line should be changed. The line could be damaged and more often the bill rubbing on the line makes surface scratches on the fluorocarbon leader which makes the line very visible. After catching a billfish run the line through your fingers and look closely at the line and you will see what I am talking about. Anytime fluorocarbon lines get scratched the leader section should be changed.

Ande makes a great fluorocarbon and monofilament leader material. This monofilament leader is the same line as standard Ande monofilament which is a premium quality medium-soft line. The line is flexible, strong, and has good knot strength.

There is some debate within the fishing community whether a monofilament leader is just as good as a fluorocarbon leader. Some anglers say that fluorocarbons high abrasion resistance and low visibility is largely a marketing tactic to charge really high prices per foot of line. Personally, I think there are advantages of fluorocarbon but they are not as significant as some people think.

Monofilament line absorbs water and the knot strength and abrasion resistance can decrease when then the line is wet. Often times people test the dry monofilament line strength. A fluorocarbon line is not invisible underwater but can reflect less light which can be an advantage.

In some cases, a monofilament leader will work just as well as a fluorocarbon leader. Other times when fishing for leader shy fish like tuna or snapper a small fluorocarbon line can be the difference between getting bites and not getting bites. If cost is a factor and you are skeptical of the advantage of fluorocarbon Ande monofilament would be a great leader material to use. Using some type of monofilament or fluorocarbon leader is definitely a good idea when fishing with a braided line.

Jinkai is a big game monofilament that is soft and has high stretch. It is made with a proprietary process that extrudes multiple nylon resins to create a soft-core and hard abrasion-resistant outer layer. The line comes in 50 or 100-yard leader coils in a mesh storage bag. This line can be used in a 20-foot section of a 400-pound test for a wahoo shock leader or a 100-foot section of a 250-pound test for a swordfish leader.

Jinkai line is used by both commercial and recreational fishermen. This big game monofilament is a popular choice when targeting a wide range of fish species including halibut, tuna, marlin, swordfish, and amberjacks.

Trilene Fluorocarbon Ice is the best ice fishing line. When ice fishing it is important to have a fishing line that resists ice build-up. Ice can build on the line near the water or on the reel. A fluorocarbon line is better than standard monofilament because it does not absorb water. There are braided lines that are made to shed water but when not fishing in a headed tent the fluorocarbon line is best at limiting ice formation.

Another advantage of the fluorocarbon line is its low visibility. When ice is covering the lake the water becomes very clear so a clear leader is important. The thinner the line the less visible it will be to the fish. For reason, it is common to use a 2-pound to 6-pound test line when ice fishing. Fish are cold-blooded which makes them lethargic. In cold water, fish will not fight nearly as hard as they do in the spring, summer, or fall. Also, the fish do not feed as often so having good-looking bait is important.


Ice fishing line

An ice fishing line is a thin light line that is less likely to build up ice and freeze. A light 2-6 pound line test is typically used for ice fishing. Trilene Fluorocarbon Ice is a good line option because the fluorocarbon line does not absorb water like monofilament. Sufix 832 braid is another good line choice at it is made with a gore fiber that is hydrophobic and repels water. This helps to reduce the amount of ice build-up on the line. In extremely cold conditions the fluorocarbon line is the better option cause it will have less ice build-up. Also, the fluorocarbon line is already low visibility without adding a leader.

Standard color options are ghosts and low visibility green. Sufix 832 Ice Braid comes in 20-pound and 30-pound options which are good when targeting big fish through the ice.


Multi-strand Cable Leader Line

Multistrand cable is used for shark rigs and trilling cable for catching wahoo. The cable is flexible and easy to wrap up and store. Common cable types are 7-strand or 49-strand and can be a bare cable or have a nylon coating. A multi-strand cable is thicker than single-strand wire but is nice because the line does not get kinked as easy. Crimps are needed to make the swivel and hook connections. The cable can not be twisted or tied.

AFW SurfStrand is the best multi-strand cable. Color options are bright and camo brown. This same cable comes as Surflon which is a stainless steel cable that is coated with either a black or clear nylon later. The nylon should be cut from the ends before adding crimps to Surflon.

The multi-strand cable is one wire made from 7 individual strands.  The result is a flexible cable that is also strong. When using multi-strand it must be connected to the hooks and swivel using crimps. The cable can not be twisted or tied.

A multi-strand cable is great when shark fishing and also works to catch barracuda,  kingfish, wahoo, and other fish with sharp teeth. Single strand wire is a bit thinner for a given line strength and is another option. The advantage of multistrand wire is that it is flexible and less susceptible to getting kinks.


Single Strand Wire Leader Line

Single strand wire is the most popular leader to catch fish with sharp teeth. This is because the wire is low-cost and easy to make leaders without having crimps. The wire is thin and less visible to fish than multi-strand cable in most cases. Thin number 4 38 pound test wire can catch small spanish-mackerel, large kingfish, and even mahi-mahi. Large #10 124 pound wire is a great leader for both large and small sharks.

The color of the wire is not particularly important as most fish being targeted with wire are not leader shy. However, occasionally you will catch leader shy fish like tuna and snapper with wire so it is good to use a thin wire that matches the environment. Bright stainless steel is good for clear water and bright days. Camo-brown is better for stained green water and low light conditions.

AFW Tooth Proof stainless steel leader wire is made of single-strand wire. Color options are bright stainless steel or camo brown. The wire is sized from number 2 a 27-pound test wire to number 19 which is a 360-pound test wire.

There are really only three-wire sizes that are needed to catch most fish. A number 4 38 pound test wire is very thin and is perfect for catching spanish-mackerel, cero mackerel, king mackerel, and barracuda with live bait. The number 7 69 pound test wire is good to add to the end of daisy chains and trolling lures when trolling for mackerel and wahoo. Finally, a number 10 124-pound test leader with a 16/0 circle hooks makes a great rig for targeting sharks that are 4-12 feet in length.

The wire length only needs to be about 12 inches for live bait rigs and trolling wire. Shark rigs should be about 6 feet in length.

Single strand wire can not be tired or crimped but twisted to make connections. The wire is connected to hooks and swivels with a haywire twisted. A line-to-wire connection can be made with an Albright knot and I demonstrate how to tie these knots in the video below.


Fly Fishing Line

A fly fishing line actually consists of up to four lines. First, the reel can have a braided backing line to act as a backup in case all the floating line is taken off the reel. Next is the floating line which is typically tapered to bring the line weight forward for easy casting. Then is the clear monofilament or fluorocarbon tapered leader. The last two feet of line is thin and is where the fly is connected. Finally, a tippet line is used to replace the thin two-foot section of a tapered leader without having to replace the entire leader.

The best fly line is almost entirely based on the size of fish being targeted. Size 1 wt reel, rod, and floating line are used for catching small panfish and small trout. A 5 wt setup is the most common size for catching trout in streams. Finally, a 9 wt would be a saltwater fly fishing setup for catch salmon, tarpon, and striped bass.

This Piscifun fly line is the best fly line backing. It comes in bright colors that can match the floating fly line on the reel. This line is not fly line but is an added line in case more fishing line is needed. Most standard braided lines would work for this but this backing braid has a bit larger diameter and works well with a fly reel.

Having a backing line on a fly reel is important when fishing for big fish like salmon, tarpon, cobia, tuna, or sharks. A standard floating fly line is only about 100 feet in length. When using light drag this is not enough line to catch large fish over around 15 pounds.

The Piscifun Sword is the best weight forward floating fly line. A good floating fly line design offers a line that flows quickly through the air and then dissipates the energy at the end to land the fly softly in the water. This fly line has a front tapper, belly, and rear taper to allows for smooth far casting with average size flies.

The end of the fly line has a welded loop which makes it really easy to attach a tapered leader with a loop to loop connection. Always put the float line through the leader when making the loop connection.

A weight-forward floating fly line is great for beginners. This tapered leader makes it easier to cast. The weight-forward line works for dry flies or nymphs flies. When fly fishing it is very important to have a line that is visible to the angler so the position of the line can be adjusted. A clear tapered leader and tippet are used near the fish so the floating line should not spook the fish in most cases. Finally, the floating fly line wt has to match the weight of the rod or it will not cast properly.

Piscifun tapered leaders are quality and have pre-tied loops. A taped leader has heavier line on the loop end which gets thinner throughout the length of the line. This helps the line turn over the line and brings the fly to the end of the line. The loop on the end of the tapped leader is a perfection loop. If the knot breaks it is easy to re-tie if you know how to make a perfection loop.

The last two or three feet of the leader is the tippet section. The rated line weight is based on the tippet line strength. The tapered leader should be about the length of the fly rod. After tying on different flies the tippet lengths will get shorter. New tippet that is equal or smaller in line-diameter can be added to the tapered leader with a line to line connection. Good knots for this are the surgeon’s knot or double uni knot.

Piscifun is high-performance fluorocarbon tippet material. The material for tippet is either a standard monofilament or fluorocarbon. Which tipped is best depends on the type of fly.

A monofilament tippet is better for dry flies as the line is not as heavy and keeps the fly floating more easily. A fluorocarbon tippet is better for bead flies nymphs that are fished beneath the surface. Fluorocarbon sinks and this can help the fly sink faster is moving currents.

A 1x tippet material is stronger than a 6x. This can confuse some people since a 1 wt fly rod is for very small fish and the higher the weight the stronger the rod, reel, and floating fly line will be. Just realize the tapped leader and tippet use a different size convention than the rod, reel, and floating line.


Lead core fishing line

A lead core fishing line has a dense lead core wrapped in a braided line or coated with nylon. The line is metered to allow the angler to know how much line has be let out without a line counter. Using a 27 or 36-pound line is a good idea because it is heavier and can get deeper with less line let out. Always add a 6-10 fluorocarbon or monofilament leader when using lead core.

Consider using a lead-core line if you want to set more lines at depths from 20-60 feet. There are various other ways to achieve the same goal. These ways include using downriggers, Monel or copper trolling wire, dipsey divers, jet divers, or a 6-ounce lead mooching weight on a flatline.

The primary advantage of lead core is it can get your lures deep without extra equipment. In my experience, about 2-3 colors (20-30 feet) of lead core will typically achieve around 10-15 feet of depth at normal trolling speeds. This varies based on speed, lure, and current though. I’ve had great success using lead core for salmon, walleye, and lake trout that suspend in the water column.

Sufix Performance is the best lead core fishing line. It has a heavy lead core with a braided fiber outer layer. A lead core line can either be coated with nylon or be made with a braided line.

A monofilament or fluorocarbon leader should be used when fishing with lead core line or wireline. Using a line to line connection or small swivel should allow the connection to through the eyes of the rod if a long 10-foot leader is used.

The depth the line will sink to depends on the boat speed, current speed, and type of lure being used. Common lures to troll with lead core are diving plugs and spoons. One way to determine depth is to troll in 20 feet of water and set line out until it taps the bottom. For an average spoon or lure letting out 20 feet of line gets the lure about 10 feet deep. So to get the lure 60 feet down about 120 feet of the line has to be set out. This line sinks deeper than running wire for a given amount line set out under most conditions.

The line is metered with 10 different color sections that change every 10 feet. This helps determine the amount of line set out which determines the depth of the lure. Using a line counter reel is the easiest wat to know how much line is off the reel. Line counter reels are commonly used for salmon and walleye fishing.


Monel trolling wire

Monel is a nickel-copper alloy wire that used when trolling to get lines deep. When running wire-line a twili-tip spring guide or roller guide needs to be installed on the tip of the rod or the wire will damage the top eye of the rod.

Fishing with wire is also commonly called trolling with copper. Monel is a slightly heavy line, more abrasion resistant, and more kink resistant than a cooper line. Monel is also thinner than a copper for any given strength. Fishing with Monel or copper is done the say way.

Monel and copper can be connected to swivels with a haywire twist or Palomar knot. Often times dacron is used as a backing line with wire-line setups. Dacron can be tied to the wire with an Albright knot. The knot should easily pass through the eyes of the fishing rod.

Fishing with wire allows baits and lures to be trolled up to about 60 feet deep without using a downrigger. It is common to use a 40-60 pound test wire. Every 30 feet of line let out gets the bait down about 10 feet. To get a bait 60 feet deep about 180 feet of wire needs to be set out. This method of trolling is done to catch salmon, steelhead, walleye, lake trout, and striped bass.

This method of trolling is done to catch salmon, steelhead, walleye, lake trout, and striped bass. Monel also works to secure anchor shackles.


Copper fishing line

Copper fishing line is a heavy wire than can get spoons and plugs deeper into the water. The typical target depth with copper wire is 20-60 feet. Copper wire is fished the same way as Monel or stainless steel trolling wire. Some anglers think the hum of the wire going through the water actually helps attract fish. Make sure a line counter fishing reel is used to know how much wire has been set out. In most cases though this copper line is used a rigging wire.

AFW rigging wire is used to secure a bait to a hook. Typically baits that are rigged with wire include ballyhoo, bonito strips, and chin-weighted mullet. An alternative to rigging wire is bait springs but many anglers prefer to rig baits with wire. Rigging wire is a type of line that is important to have on an offshore fishing boat, especially when fishing for mahi-mahi, marlin, and large tuna. Bass Pros Shops Offshore Angler has a similar type of rigging wire cut to 9-inch lengths.

This one-pound spool has about 792 feet of copper wire. AFW copper wire is also available in pre-cut 9-inch or 14-inch pieces. It is about 6 times cheaper to get the one-pound spool than the pre-cut length wire.

Ballyhoo are rigged with wire when trolling naked ballyhoo or skirted ballyhoo. The wire is wrapped around the head of the bait which if done properly allows the bait to be dragged in the water straight without spinning. Bonito strips are added to skirted baits such as metal-head stubby bubbler to add scent and flash to the bait. Rigging mullet with wire is done by adding a chin weight so to act as a keel to keep the bait running upright.

Tuf Line Dacron is the best Dacron fishing line. This was the most popular type of fishing line before the 1960s. Today braided fishing lines have been improved with new materials like Spectra, Dura, and micro-Dyneema. This has made the line much thinner for any given strength.

A thin light line is very important when casting. However, Dacron a thick braided line is still used today on conventional fishing reels. Mostly for a backing line to fill up large offshore fishing reels. Dacron is susceptible to line rot and UV damage where modern braided lines are not. It is a backing material and when it does not see light or water very often it can still last multiple seasons. This is why you will get mixed options on how long a Dacron line lasts. Some people say it rots quickly and others say it lasts for years. It really depends on how it is used. Some anglers also like a thick Dacron line because it does not cut into the skin as easily as a thin braided line when leadering fish.

A braided nylon twine is the best halibut leader material. This line in number 36 is good for making halibut leaders. The exact line I use for halibut leaders is Ashaway tuna leader, which is a solid braided nylon cord and is rated as a 150-pound test.

Halibut are not leader shy and mostly feed based on scent. For this reason, a thick braided line can be used. A short 100-plus-pound monofilament leader is still used to attach the hook. A heavy braided line is used to connect the hooks when commercial fishing for halibut using a halibut skate.

This line is great for making halibut fishing rigs. Halibut can also be caught with salmon mooching rigs with herring, swim jigs, vertical jigs, and pipe jigs. The best way to catch halibut though is to use fresh dead bait like pollack, herring, squid, or pink salmon.


 Braid Monofilament Line Diameter Chart

The diameter of a fishing line is important because it determines how much fishing line a reel can hold. Reels often give the line capacity rating based on average monofilament line thickness. To determine how much-braided line the reel can hold the capacity of the equivalent braid-diameter should be used. For example, if the reel says it holds 150 yards of an 8-pound test it will hold about 150 yards of a 30-pound braided line. The diameter of the line is typically provided in mm or inches. Fluorocarbon line diameters are typically very similar but slightly smaller than a nylon monofilament line.

Common Questions About Fishing Lines

Can a fishing line be invisible?

No fishing line is actually invisible. Certain fishing lines reflect less light and depending on the color can blend into the surroundings to become much less visible. A thin fluorocarbon line is the best at reflecting less light since the index of refraction is closer to water. Colors for fluorocarbon and monofilament can be clear, green, smoke, red, gold, pink, and blue to best match the color of the water and surrounding environment.

Braided fishing line is thinner than monofilament but is still typically more visible. For this reason, a monofilament or fluorocarbon leader is typically used. If the proper color braided line used it can be much less visible in the water. White is a good color to use near the surface on bright days as it can blend into the sky. Dark green is a good color in low light and murky water conditions. Above water, it is best to have a visible line so anglers can see where the line is and prevent tangles.

What color fishing line should I use?

The best color fishing line is one that the fish can not see below water and the anglers can see above water. The best color depends on lighting and water conditions. Most anglers use a clear line for monofilament and fluorocarbon and moss green for braided line. These are good color choices but there are many other good color lines available. White braid and multi-color metered braided lines are also good options. Ultragreen is a popular monofilament color used in stained water.

Being able to see the fishing line above water is also important. There are lots of bright color lines such as high visibility yellow, neon, solar, white, and fluorescent orange that are easy to see above the water. Lead core line and metered braided lines have colors that change at set distances which allows anglers to estimate line depths.

What fishing line works for spinning reels?

The best fishing line for spinning reels for casting distance is braided fishing line. Monofilament line works well for casting up to a 30-pound test. Berkley Trilene XL smooth casting is the best monofilament line for spinning reels. It is soft flexible and has low memory which allows for far casting. Berkley Vanish is a good line for spinning reels when using a light 4-6 pound test line when trout and crappie fishing. Spinning reels come in various sizes so selecting a reel that holds enough line and has a proper drag rating for the size fish being targeted is important.

Is braid stronger than monofilament?

Braid is stronger than monofilament based on the thickness of the line. Also, braid can have a higher knot strength than monofilament especially when comparing the wet knot strength. Braided line is a static rope and does not stretch. In some ways this makes it stronger however the line does not absorb high impact shocks as well. A monofilament line can stretch rather than breaking from a strong fish head shake for example.

Is monofilament or fluorocarbon better?

In some cases, a monofilament fishing line is better and in other cases, a fluorocarbon line is better. As a leader material fluorocarbon is typically a better line as it is less visible and more abrasion resistant when wet. Fluorocarbon is more expensive and in some fishing situations, a monofilament leader is all that is needed. Also, some colors of monofilament like ultragreen or pink help make monofilament very low visibility in certain water conditions.

A fluorocarbon line is UV resistant has a self-life of around 7 years compared to a 2-3 year self-life of monofilament. As a mainline monofilament is typically softer and has less memory which is important when using spinning reels. For this reason, a fluorocarbon line is rarely used above 20 pounds. However, Berkley vanish does make fluorocarbon lines up to 40 pounds. This line can also be used as leader material.

What is high visibility line used for?

A high visibility line allows the angler to see the line above the water. This allows the lure or baits location to be determined by following the line into the water. When fighting fish sometimes lines get crossed and a high visibly line makes it easier to determine which rod should go over or under each other to not get tangled. Also being able the see the line helps give a better idea of how far back the lures are even when they are submerged underwater. There are also lines that show up well under a blacklight above the water and are good to use when night fishing.

How do you get rid of line memory?

Line memory is a fishing line staying the shape based on its previous position. If a fishing line is wound tightly on a round spool for even a few hours when the line comes off the spool it can be in the shape of coils. This is not a good thing and ideally, the line would have zero memory which is the case with a braided line. Stiff fluorocarbon and monofilament lines do have significant memory.

If the line memory is the shape of the reel spool it should not create tangles. If the memory is the shape of the spool the line came on it can create tangles. To avoid this the line should be placed tightly on the spool many hours before the line will be used. The spool-of-line can also be soaked in fresh-water for 20 minutes and then dried out to change the memory of the line to the spool. The thinner and softer the monofilament is the less memory it will typically have.

What type of fishing line is used for saltwater?

The best fishing line for saltwater depends on the type of fishing. A thin fluorocarbon line is best for small snappers, grunts, groupers, and porgies. A 30-pound monofilament line is great for inshore, reef, and offshore fishing on spinning reels. The leader matters should be thinner or larger based on the fish being targeted. For conventional reels, a 30-130 pound monofilament is a good option depending on the size of fish being targeted.

A braided line is very good option when fishing deep offshore. The line is thin and is affected less by ocean currents. Braided line also allows reels to hold significantly more fishing line. This allows for smaller lighter gear to be used which is great for stand up fishing.

What is the fishing line is easy to use with a baitcaster?

Baitcastiering reels are prominently used by bass fishermen. This means that both braid and monofilament are good lines to use depending on the type of lure. Heavy jigs can be easily pitched a short distance with braid or monofilament line. When casting for distance braided line is much easier to use because the line has no memory and is less likely to backlash. Experienced bass freshmen can use either type of line while beginners will have a much easier time using a braided line. The key to using a baitcasting reel is to always have finger control of the spool speed to prevent backlash and to control the lure’s speed for a soft landing.

Is the diameter of a fishing line important?

Yes, the diameter of a fishing line is important. The line visibility of fluorocarbon and monofilament is largely dependent on diameter. For this reason, a thin 6-pound test line will be much less visible to a fish than the same line with a 60-pound test. Some types of fluorocarbon are thinner than others for the same pound test so this should be compared when selecting a fishing line. In this article, I show the 20-pound line diameters in millimeters for this purpose.

Lines that are thinner and lighter will create less drag when casting a lure. This is why a thin braided fishing line can be cast super far. Thin monofilament lines also cast far. It is always surprising to me how far light lures cast when using a 4-pound test line for example. The diameter of the line also affects how-much line a reel can hold. Sometimes more of a lighter line is better than less of a heavy line. When using braid line capacity is rarely an issue and anglers tend to get line much stronger than is needed.

What fishing line floats?

Braided line floats, monofilament line sinks, and fluorocarbon line sinks fast. A floating line is actually very useful to use as a strike indicator. For example, I use a floating braided line as a strike indicator when bass fishing with soft plastics. The lure is cast out and then the bait sinks slowly for ten seconds. Extra line floats on top of the water and is slowly pulled down by the lure. Any change is speed means that the bait hit the bottom or that a bass bit the lure. In either case, it is time to quickly reel up the slack and set the hook if a fish is on the line. If the angler is not paying attention to the line the bass can spit the lure or swallow it and get gut hooked. This is why a floating braided line can be very important to use.

A floating braided line is also helpful to determine when a lure reaches the bottom. When jigging or dropping baits I tend to pull up slowly and down quickly to leave loose line on the surface of the water. This ensured that no extra drag is added to lure. When the floating line stops being pulled down it has reached to bottom or the bait has been taken by a fish.

How much fishing line is needed on a spinning reel?

It is common for a spinning reel to hold 150 years of fishing line. With most lures under one ounce, the furthest and angler can cast is about 40 yards. The remaining line is needed in the event that a fish pulls line off the reel after being hooked. A reel that is underfilled can cause extra drag as the line leaves the spool resulting in a decrease in casting distance. An overfilled spool can cause line to wrap around the rotor and get tangled during the cast.

As a spinning reel is used the line on the reel will get shorter as lures are changed or damaged line near the end is taken off. There is no set rule of how much line needs to be on a reel. When ice fishing, 50 years is typically enough. Reels used to fish in streams for trout typically hold 100 yards of line. A standard bass fishing reel holds around 150 yards of line and should never have less than 100 yards on the spool. For offshore saltwater reels, a typical 7500 size reel holds 220 yards of 30-pound line or 440 yards of 65-pound braid.

How much fishing line is needed on a conventional reel?

Conventional reels can be small level wind reels for bass fishing to large 130 class reels for catching 1000-pound marlin and bluefin tuna. Small conventional reels for freshwater trolling hold as little as 185 yards of 16-pound line on the Shimano Tekota 300. When salmon fishing a Tekota 600 is a great size reel and can hold about 300 yards of 30-pound monofilament.

A perfect size convention reel for saltwater trolling is a 30 class reel. It is small enough for stand up fishing and big enough to catch 200 plus pound fish. A 30 class reel can hold about 600 yards of 50-pound monofilament or 1435 yards of 80-pound braid. For deep dropping for daytime swords, it is common to use an 80 class reel with over 3,000 yards of 100-pound braided line. The largest 130 class conventional reels can hold 1300 yards of 100-pound monofilament or 4175 yards of 130-pound braided line.

What fishing line is most sensitive?

The most sensitive fishing line is a braided line. This line is static meaning that it does not stretch. The result is that all the force gets transferred to the rod. When using a braided line with a sensitive rod every little nibble can be felt through the handle of the rod. This provides significant information to the angler about what is going on with the bait.

The second most sensitive line is fluorocarbon. This line has less stretch than monofilament resulting in more of the energy being transferred to the rod. A monofilament line is the least sensitive but still transfers energy to the rod. When talking about sensitivity it is important to note that the line has to be under tension to feel bites. If the line is slack very little force from a bite will be transferred to the fishing rod.

Fluorocarbon Leaders: When, Why, and How to Use Them Effectively

Fluorocarbon fishing line has several distinct properties that separate it from standard monofilament line. The primary reason anglers reach for fluorocarbon lines or leaders is reduced visibility underwater. While marketing claims of “invisible underwater” are exaggerated, there’s science behind why fluorocarbon can be less detectable to fish.

Fluorocarbon has an index of refraction of 1.42, while standard monofilament is around 1.55 and water is 1.33. Since fluorocarbon’s refractive index is closer to water, it bends and reflects less light in certain conditions. The thinner the line, the less visible it will be. When fish can be seen but aren’t biting, switching to a thin fluorocarbon leader is a tactical adjustment that often produces results.

Key Benefits of Fluorocarbon Leaders

Superior Abrasion Resistance

The second major advantage of fluorocarbon is its enhanced abrasion resistance compared to monofilament. This becomes crucial when targeting species like bass, snook, and tarpon with rough, abrasive mouths that can wear through standard lines. The abrasion resistance is particularly valuable when pursuing billfish such as sailfish, marlin, and swordfish, whose bills can quickly fray lesser materials.

Density and Sink Rate

Fluorocarbon is denser than standard monofilament and sinks in water. This characteristic reduces slack when dropping baits and jigs, providing better sensitivity and control. The line’s stiffness helps prevent underwater bunching but can sometimes limit the action of smaller live baits.

Practical Applications

For fishing lines over 20 pounds, standard monofilament is typically used for the mainline because fluorocarbon becomes too stiff at higher weights. Using just a fluorocarbon leader instead of spooling entirely with fluorocarbon is also more economical. Fluorocarbon leaders particularly shine when paired with braided main fishing lines, combining the strength and sensitivity of braid with the low visibility and abrasion resistance of fluorocarbon.

Ande makes high-quality leader material at a reasonable price point. Using a 20-pound test is perfect for bass fish and a 50-pound test is good for tarpon and striped bass. The wrist spool the line comes on is a good way to store the line. Fluorocarbon should last for up to seven years if stored properly. The spool contains 50 yards of the fluorocarbon leader line. I use Ande leader line for both freshwater and saltwater and think it is the best for strength and low visibility under the water.

Like most fluorocarbon Ande line is clear, abrasion-resistant, and heavier than water.  The line is stiff and does not stretch as much as traditional monofilament. When fishing with braid and fluorocarbon leaders there will be little stretch in the line. This can be good to get a quick hookset but does not absorb quick movements from strong fish. For this reason, reels with quality drag and somewhat flexible poles should be used when fishing with braid and fluorocarbon.

Seaguar Blue Label fluorocarbon is one of the most most popular fluorocarbon leaders. This is a double structure fluorocarbon that uses two fluorocarbon resins that make the line in a co-extrusion process.  This line is low-visibility, abrasion resistant, has a high knot strength, and is fast sinking.

This line comes in 25, 50, and 100 yards spools. Typically leaders are about 5 feet long for fish like bass, crappie, trout, and tarpon. Leaders are often made ten feet or longer when fishing for tuna, yellowtail snapper, and mutton snapper which can be leader shy. Sometimes fish are not leader shy and even tuna which have great eyesight will bite a thick wireline. However, there are times when the water clarity, sunlight, and fish activity level make having a less reflective fluorocarbon leader an advantage. Sometimes just using a fluorocarbon leader is not enough and the angler should use a smaller diameter fluorocarbon leader. This is common when fish or highly pressured salmon, trout, and snappers.

When fishing in dirty water it is also important to keep the line clean. Dirt can build up on the line making it more visible. Wiping the line with a clean cloth can help make the line less visible at times. Also if fluorocarbon was on a small spool if often has coil memory, stretch the leader line straight to make it less visible.

This is the same Seaguar Blue Label fluorocarbon but is found at a much higher strength. The fluorocarbon leader line comes in a 32.8-yard spool in a reusable mesh bag with a zipper. When making shock leaders for wahoo or swordfish with a braided mainline standard monofilament line should be used because it has more stretch. Heavy fluorocarbon is used because it is less visible and abrasion-resistant. The leader for billfish should be fluorocarbon or heavy monofilament as the bill rubs on the line a can break the monofilament line easier.

When trolling offshore for tuna, marlin, and mahi-mahi it is common to use 100-200 pound, fluorocarbon leaders. The leader will need to be attached with crimps as the line will be to thick to tie with most fishing knots. When using an 80-pound line fishing knots like the palmer knot can still be used. Some anglers even use 200-pound fluorocarbon when a wahoo might be caught when trolling for other pelagic fish. Wahoo teeth can defiantly cut 200-pound fluorocarbon but some wahoo lures typically catch the corner of the mouth and the teeth will be over the lure, not the line. The heavy line offers some protection from the initial bite but the line still might get cut.


Fluorocarbon Leader Selection Considerations

Diameter and Strength Balance

When selecting a fluorocarbon leader, consider both the pound test and the diameter. The thinnest diameter fluorocarbon leader on the market is often the best choice for highly pressured or line-shy fish. For a 20-pound test leader, diameters typically range from 0.370 mm to 0.45 mm depending on the brand and model.

Leader Length

The appropriate length of your fluorocarbon leader depends on fishing conditions and target species. My typical leader length for casting setups is about 5 feet, which prevents the connection knot from having to pass through rod guides while casting.

For trolling applications, a 6-foot leader attached with a quality ball-bearing swivel works well in most scenarios. Some species like mutton snapper may require leaders exceeding 30 feet, while yellowtail snapper might necessitate dropping from 20-pound test fluorocarbon to 10-pound to generate strikes in clear water.

Line Care and Presentation

When fishing in dirty water, keeping your fluorocarbon leader clean is essential. Dirt buildup on the line increases visibility, so periodically wiping the leader with a clean cloth can improve stealth. Similarly, fluorocarbon stored on small spools often develops coil memory. Stretching the leader straight before use makes it less visible to fish.


Fluorocarbon Leaders vs. Fluorocarbon Line: Understanding the Difference

Before diving deeper into applications, it’s important to understand the distinction between fluorocarbon leaders and fluorocarbon fishing line:

Fluorocarbon Leaders

Fluorocarbon leaders are specifically designed to be tied to your mainline as the final section before your terminal tackle. These leaders are typically sold in shorter lengths (25-100 yards) and are optimized for:

  • Maximum abrasion resistance
  • Minimal visibility
  • Optimal knot strength
  • Higher pound test ratings (often up to 200+ pounds for big game applications)

Leader material is generally stiffer and more durable than full-spool fluorocarbon line, making it ideal for the business end of your setup where encounters with fish and structure occur.

Fluorocarbon Fishing Line

Fluorocarbon fishing line is designed to be used as your mainline, spooled directly onto your reel. Compared to leader material, it features:

  • Better castability through reduced memory and stiffness
  • More manageable handling characteristics
  • Generally lower pound test ratings (typically 2-40 pounds)
  • Slightly less abrasion resistance than dedicated leader material
  • Often comes in larger spools (200+ yards)

When spooling with fluorocarbon line, you are getting the benefits of fluorocarbon throughout your entire setup rather than just the leader section, but at the expense of some durability and potentially increased cost.

Berkley Vanish fluorocarbon is a fishing line not just a leader material. That being said the line is very similar in diameter to most fluorocarbon leader materials. It is also abrasion-resistant. For these reasons, it would work well as leader material for braided or monofilament lines. The line is made with 100 percent soft low-memory fluorocarbon and is not fluorocarbon coated. I would recommend using this line rather than any monofilament line under 10 pounds.

This line is also flexible and easy to cast compared to other fluorocarbon lines. For small diameters around 4-6 pounds, the line is very flexible. The line is made in 30 and 40-pound tests which are higher than most fluorocarbon lines. This is because the line will not cast as far with spinning reels. However, the heavy fluorocarbon line can be used on conventional fishing reels.

Stern Fluorocast is another good fluorocarbon fishing line. It is made for tests between 6 and 17 pounds. Using a fluorocarbon line is easier than using braided or nylon monofilament with a leader as there is an extra knot in that setup. That knot reduces the over line strength and creates a weak spot that is around 80 percent of the overall line strength.

The 17-pound Stern Fluorocast has a diameter of 0.40 mm which is the diameter of 20-pound Berkley Vanish. For that reason, I think Berkley Vanish is a better product but the two lines are very similar. These lines are sensitive for felling bites and offer some stretch to absorb shock while catching a thrashing fish. This line has good knot strength, low visibility underwater, and is a sinking line that helps get baits and lures deep in the water.

I think the Berkley Vanish is the better fluorocarbon line but some anglers prefer Seaguar fishing line.


When to Use Fluorocarbon vs. Other Materials

Fluorocarbon vs. Monofilament

Fluorocarbon leaders are almost always advantageous over standard mono leaders. For fishing lines under 10-pound test, using fluorocarbon for the entire line often makes sense. For spinning and baitcasting reels, a braided mainline with fluorocarbon leader provides optimal casting distance and stealth.

Fluorocarbon lines up to 40 pounds can be effectively used on conventional fishing reels. The material offers a balance between the stiffness and stretch of monofilament and the no-stretch quality of braided line. When abrasion resistance or low visibility is crucial, fluorocarbon is the superior choice.

Fluorocarbon vs. Wire Leaders

While fluorocarbon excels against abrasive fish mouths, it won’t prevent cuts from the sharp teeth of sharks, wahoo, or mackerel. For these toothy predators, single-strand wire or multi-strand cable leaders remain necessary despite their increased visibility.

Some species like salmon and halibut aren’t particularly leader-shy, so standard monofilament can sometimes be used without reducing catch rates.


Common Questions about Fluorocarbon Leaders. 

Does fluorocarbon leader make a difference?

Yes, a fluorocarbon leader line can make a difference in some situations. It has several differences that can be considered an advantage or a disadvantage depending on the situation. First, fluorocarbon can be less visible than monofilament because the index of refraction of 1.42 which is close to the 1.33 value of water. Second, fluorocarbon is dense which makes it abrasion resistant, thin, and sinks in the water. Sometimes when fishing a small floating topwater lure a sinking line is not desirable. Also since the line is denser, it is also stiffer than nylon monofilament which makes it more difficult to cast if it is used for the entire length of the line.

Fluorocarbon is great to use a leader in most cases. Fluorocarbon helps against abrasive mouths of fish like bass, tarpon, and snook. However, it does not prevent sharp teeth from a shark, wahoo, and mackerel from cutting the line which is why single strand wire or multi-strand cable is typically used. Also, some fish spices like salmon and halibut are not leader shy and a standard monofilament line can be used without changing the catch rates.

How much fluorocarbon leader should I use?

There are two important factors that determine the visibility of fluorocarbon to fish. The length of the leader and the thickness of the leader. Fourcarbon is less visible to fish but is not invisible. Some days fish are aggressive and will bite on a thin metal wire. Other day’s conditions are such that fish are skittish and will not bite large rigs with a heavy line. My typical leader length for casting is about 5 feet. This makes it so the knot does not have to go through the eye of the pole reducing the casting distance.

When trolling a good leader length is 6 feet and the lure should be attached with a good ball bearing swivel. Some fish such as mutton snapper requires a long 30 foot plus leader lengths. Other fish like yellowtail snapper might require going from a 20-pound test fluorocarbon to a 10-pound test fluorocarbon in order to get bites. Thinner fishing lines are less visible to fish than thicker lines.

Should I use monofilament or fluorocarbon?

Fluorocarbon leaders are almost always a good idea. When using a fishing line that is less than a 10-pound test fluorocarbon for the entire line is a good idea. For spinning reels and baitcasting reels using a braided mainline allows for the furthest casting. When using a braided line fluorocarbon leaders should almost always be used. Fluorocarbon lines are made up to 40 pounds which can be used on conventional fishing reels. This line is stiffer with more stretch than a braided line and less stretch than a nylon monofilament line. If abrasion resistance or using a low visibility line is important fluorocarbon should be used. Abrasion resistance can be important from the standpoint of the fish’s mouth as well as the bottom or other areas that the line might rub on.

What are the best knots for fluorocarbon leaders?

The best knots for fluorocarbon leaders are the unit knot and the Palomar knot for attaching hooks. When attaching the leader to a braided or monofilament line the double uni knot is quick and effective. Perfection loops and dropper loops are also commonly used to tie leaders. The video below shows the best fishing knots to use for all types of fishing situations.

Do I need a leader on braided line?

In almost all cases leaders are a good idea with a braided line. Some fish like halibut and catfish are not leader shy and so braided line can be used without a fluorocarbon leader. Sometimes the desirable leader’s strength should be more or less than the mainline. In these cases, a heavy braided line, single-strand wire, multistrand cable, or fluorocarbon line should be used as the leader.

The visibility of a braided line depends on the color of the braid and the color of the environment. Common colors of braided lines are white, yellow, black, and green. White is probably the best color at having love visibility in clear water. When fish look up the sky is a light color and white is good camouflage. In stained, murky, or low light conditions a dark green is a low visitability braided line.

What is the leader line?

A leader line is the last 3-20 feet of line that is connected to a hook or lure. It is connected to the mainline with a swivel or line-to-line connection such as the double uni knot. The leader line can be a variety of materials including a fluorocarbon line, nylon monofilament line, multi-strand cable, single strand wire, braided line, or even a rope such as a solid braid nylon core ganyen leader line. It is common to use a leader line that is stronger than the mainline to account for any damage that may come to the line from rubbing on the bottom, cut by the fish’s teeth, or when rubbing against an abrasive fish’s body.

Which is stronger mono or fluorocarbon?

The strength of a given fish line depends on several factors. There is the line strength, knot strength, shock absorbance, abrasion resistance, and cut resistance. The line strength can be from 2 pounds to 400 pounds but the diameter of the line increases as the line gets stronger. It is good to compare the thickness of the line at a given pound test. In this article, the line diameter is given for a 20-pound test line. Fluorocarbon and monofilament have similar line diameters and it varies depending on the brand and model of the line. The thinnest diameter fluorocarbon leader line on the market is Seaguar gold. For a 100 percent fluorocarbon fishing line that is used for the entire spool, the thinnest diameter is Berkley Vanish.

How long does a fluorocarbon line last?

A fluorocarbon line lasts longer than a standard nylon monofilament because it does not breaks down as fast from UV light. The shelf life of fluorocarbon is about 7 years. Once fluorocarbon is on a reel and used it should be replaced once a year at the beginning of the season. If it is rarely used it should last two or three years. When using an old line always test the knot strength by pulling hard on the line. If it does not break easier than expected it should work. Once you have a line break with properly set drag it is time to replace the fishing line.

Is fluorocarbon good for baitcasters?

This short answer is no fluorocarbon is not good for baitcasters. Fluorocarbon is not as soft as standard nylon and will bird nests easier. Some fluorocarbon brands are softer than others. If it is a fluorocarbon fishing line and under 10 pounds an experienced angler could use a baitcaster reel. A braided fishing line is the easiest to use with a baitcaster and then a fluorocarbon leader can be added.

Can you use fluorocarbon as a mainline?

Yes, fluorocarbon line from 2 pounds to 40 pounds can be used as the mainline. Fluorocarbon under 10 pounds works best for spinning reels. Large fluorocarbon can be used on convection fishing reels when trolling and jigging. When trout, steelhead, and salmon fishing a fluorocarbon mainline is nice because a leader is not needed. A fluorocarbon mainline is also nice when fishing for yellowtail snapper.

Should leaders be heavier than the mainline?

Yes in most cases a leader should be stronger and heavier than the mainline. This is because the line might rub against rocks or be damaged by the fish’s teeth. Fluorocarbon is great leader material because it has low visibility and is abrasion-resistant. Another good leader material is single strand wire or multi-strand cable when fish have sharp teeth.

Is a fluorocarbon line really invisible?

No fluorocarbon line is not invisible above water or underwater. This is mostly a false marketing technique to get anglers to buy a really expensive fishing line. It is less visible under certain conditions. When direct sunlight hits a fishing line the reflection can scare away fish. With fluorocarbon, the reflection is still there but it is not as much. The thinner a fishing line is the less visible it should be. This is why using a 2-6 pound test is common when trout fishing for example.

Is fluorocarbon hard to cast?

Yes, fluorocarbon is harder to cast than a nylon monofilament or braided line of the same strength. This is because the line is denser and stiffer than these other lines. The result is that it will not cast as far. There are advantages of using fluorocarbon though and if the line is under a 10-pound test is should be cast about the same as the other lines.

Can you use fluorocarbon on a spinning reel?

Yes, a fluorocarbon line can be used on a spinning reel. It will not cast as far as a standard nylon line or braided line. Braided lines cast the furthest since they are lightweight and extremely flexible. Braided lines are quite visible to the fish though which is why fluorocarbon leaders are almost always used.

What’s better braided or fluorocarbon?

Braided line and fluorocarbon are two very different types of line and are better in different situations. For a mainline fluorocarbon is only common for less than a 10-pound test. A braided line is a great mainline from 10 pounds to 200 pounds. Both braided line and fluorocarbon are abrasion-resistant. Fluorocarbon is a much better leader material though since it is less visible under most conditions.

What is fluorocarbon made of?

Fluorocarbon material is a fluoropolymer PVDF. This material starts as a resin and is then extruded into a fishing line. Most Seaguar leader material is double structure fluorocarbon that is made in a co-extrusion process. PVDF is a desirable line material because it has an index of refraction that is close to that of water. This makes the line less visible to the fish. It is also a dense fishing line that sinks and holds up well to knicks and scrapes.

Does fluorocarbon have memory?

Yes, a fluorocarbon line is a type of monofilament and has memory. Memory is actually a good thing in most cases. It is important to spool monofilament and fluorocarbon lines at least the night before using it. If not the line is more likely to get tangled coming on and off the spool. When using fluorocarbon as a leader it is important to remove the memory from the line. This can be done by pulling hard on the line. This will stretch the line for a second which removes most of the memory in the line. A straight line is less visible than a line with curly wraps.

When was fluorocarbon invented?

Fluorocarbon was invented in 1971 by people working at Seaguar. Many anglers will say you need fluorocarbon to catch tuna or trout but there was plenty of tuna and trout caught before the fluorocarbon line was invented. There are advantages of this line though as it is a tougher less visible line. A heavier line can be used as still be equivalent to the visibility of a smaller diameter nylon line. Fluorocarbon is both tougher and less visible in most fishing situations.

Can fish bite through fluorocarbon?

Yes, some fish can absolutely bite through fluorocarbon. When it comes to large sharp teeth of fish fluorocarbon offers about the same durability as a standard nylon fishing line. It is more abrasion resistant which is good for fish that have sandpaper-like teeth. The line is also very durable when rubbing against the bills of sailfish, marlin, and swordfish.
