Best Fluorocarbon Lines in 2021 – Buyer’s Guide

There are countless reasons why fluorocarbon fishing lines have taken up almost a quarter of the market. They are robust, nearly invisible underwater, and in possession of adequate stretch. 

Fluorocarbon fishing lines are made out of premium organic and synthetic compounds. Mainly, these compounds are carbon, fluorine, and chlorine, which are collectively called polyvinylidene difluoride. 

These top-notch strands are interwoven tightly, creating a highly resilient fishing line with low memory. Some companies prefer a hybrid line consisting of a copolymer core coated with fluorocarbon, while others opt for a 100% fluorocarbon fishing line. 

Throughout this article, we will show you our eight top picks for the best fluorocarbon lines available on the market. Moreover, we will break down a simple guide that will aid you in your research.

The 8 Best Fluorocarbon Lines in 2021

1. Berkley Vanish – Best Overall

Berkley Vanish

This fluorocarbon fishing line was named “Vanish” for a reason. It has an ultra-high reflective index, making it completely invisible underwater. 

Hence, the Berkeley is an ideal pick for fishing in crystal clear water, especially if you’re going after finicky fish as it has been designed with an improved direct profile from the top of the line all the way to the lure boosting its sensitivity quite a few notches. This also means that it is suited for deep water fishing. 

Unlike many fluorocarbon fishing lines, this one has excellent knotability as it does not absorb water and therefore manages to maintain its integrity and structure. Furthermore, it boasts superior anti-abrasion and anti-shock qualities, making it one of the most robust fluorocarbon fishing lines on the market today. 

It is quite flexible and versatile as it comes in sizes ranging from 20 to 100 lbs, a diameter of 0.30 mm, and different lengths between 20 and 2000 yds, allowing it to be used either as a leader or a line.  

All of these qualities allow it to cast far, wide, and smooth. Plus, it comes in three different colors. Lastly, it is quite affordable, so you won’t have to break the bank to purchase this Berkley line. 

However, the downside here is that the line might appear a little bit frayed. This might be some quality control problem as it is not a general complaint.


  • Incredible strength 
  • Excellent knotability 
  • Affordable 
  • High sensitivity 
  • Great visibility 
  • Doesn’t absorb water


  • Can appear frayed

Final Verdict

You can hardly go wrong with this line; it is strong, flexible, smooth, durable, and almost entirely invisible underwater. It will undoubtedly maximize your gain without hitting your wallet too hard.

2. KastKing FluoroKote – Runner Up

KastKing FluoroKote

Our winner of the ICAST 2015 is certainly a worthy opponent of the Berkley Vanish. This line is a hybrid made out of a copolymer core that’s coated with 100% fluorocarbon. 

What this combination does is that it brings the strength, durability, and abrasion resistance that comes with the copolymer, while maintaining the excellent visibility, lightness, low stretch, low memory, resistance to elements, and fast sinkage that come with fluorocarbon. 

It is also quite versatile as it comes with different pound tests ranging between 4 and 30 lbs and different diameters between 0.18 and 0.48 mm. 

Moreover, this line has excellent castability as it comes in a 300 yds spool. This means that it can be used as either a leader or a line, whichever suits you best. With all of these great features, KastKing still managed to place this fluorocarbon fishing line in the “affordable” category. 

Some disadvantages that come with this line include the fact that it does not work with topwater baits as it sinks rather quickly, plus it has low sensitivity.


  • Invisible in water
  • Affordable 
  • Low water absorption 
  • Excellent abrasion resistance
  • Low memory
  • Copolymer coating


  • Low sensitivity 
  • Doesn’t work with topwater baits

Final Verdict

This line is an excellent option if you’re going for deep water fishing or if your target fishing spot will be a rocky place, as it boasts superior strength and abrasion resistance.

3. Seaguar Red Label – Best for Baitcasting Reels

Seaguar Red Label

Naturally, if you’re using a baitcasting reel, you are on the more experienced side and aiming for trophy catches, not just any fish. That’s why this line will be an ideal fit for you. 

It enjoys superior abrasion resistance and very low friction due to its small diameter, 0.31 mm, which together allow you to spool it easily and to spool a lot of its 200 yds. 

It is chemically treated so it’s entirely resistant to the UV light rays, and it does not absorb water, so it does not deteriorate over time. It is 100% fluorocarbon; thus, naturally, it sinks fast and is entirely invisible underwater. Your trophy catch will be none the wiser. It is also not affected at all by temperature, no matter hot or cold. 

Furthermore, this line is affordable and can be used as either a leader or a line; it will do well in both. Lastly, it is quite versatile as it comes in different pound tests from 4 to 15 lbs. 

Nonetheless, some defects come with it, including a relatively high memory, which requires constant and thorough maintenance in order to prevent tangles. Plus, it has low knot strength, so you might want to try several different knots to find one that will work well with your needs.


  • Great visibility 
  • Abrasion-resistant 
  • Doesn’t absorb water
  • Resistant to elements
  • Resistant to extreme temperatures 
  • Easy to spool
  • Low friction 


  • Low knot strength 
  • High memory 

Final Verdict

This fluorocarbon fishing line by Seaguar is genuinely a beast. It is designed for strong finicky aggressive fish that will give anglers a run for their money as has superior strength and durability due to both its chemical treatment and core structure

4. RUNCL PowerFluoro – Best for Spinning Reels

RUNCL PowerFluoro

This fluorocarbon fishing line by RUNCL is another hybrid that is designed specifically for spinning reels as it is incredibly smooth and is in possession of excellent castability. 

Naturally, the copolymer core gives it incredible strength, durability, and abrasion resistance, while the fluorocarbon coating makes it almost completely invisible underwater as it has a light refractive index. 

Moreover, it has a thin diameter ranging between 0.23 and 0.48 mm, low memory, low stretch, and excellent sensitivity. It also boasts high-density construction, which along with the previous features, make it ideally suited for ice fishing. 

Along with the strong structure, the little stretch allows the RUNCL to take aggressive attacks in stride and keep the momentum to strengthen its position further.

One more thing is that this line is quite versatile, it can lift a lot of different species as it has a pound test ranging between 5 and 32 lbs, and it comes in the lengths between 300 and 1000 yds. 

Unfortunately, this line is not suitable for saltwater fishing as saltwater will cause damage to its structure.


  • Copolymer core
  • Fluorocarbon coating
  • Great visibility 
  • Versatile 
  • Smooth
  • Low stretch 
  • Doesn’t absorb water 
  • High Density 


  • Not suitable for saltwater fishing

Final Verdict

This stealthy line is a great option. The low stretch, high density, and fast sinkage allow it to work perfectly with spinning reels to achieve maximum strike.

5. P-Line Floroclear – Best Casts

P Line Floroclear

This Floroclear line is, at first sight, your basic fluorocarbon line with all of the great features that come with this specific category of fishing lines. These include great visibility, low stretch, low memory, lightness, not absorbing water, and being unaffected by the environmental elements. 

Yet, there is one critical feature that comes with this line, which is its superior castability. You see, all fluorocarbon lines are, logically, coated with fluorocarbon. However, this simply wasn’t enough when it came to this specific line. Hence, the added silicone coating took the smoothness, sleekness, and castability of this line to a whole new level.

It also reduced the already low memory creating a hassle-free experience for anglers. Moreover, it enjoys simple and secure knots that you can count on and is highly versatile. It boasts pound tests ranging between 2 and 30 lbs, comes in the lengths 260-300 yds, and has diameters ranging between 0.13 and 0.5 mm. 

But, of course, every product must have its defects and here we will have to speak about the quality control problems. Sometimes, the silicone might come off the line leaving it quite bare.


  • Great visibility 
  • Silicone finish
  • Excellent casts
  • Secure, easy knots
  • Low stretch 
  • Low memory


  • Quality control 

Final Verdict

This line here is excellent for long day trips when you’re planning on covering large areas of your waterfront. It can cast wide, far, and long with unprecedented smoothness. We have not seen the silicone coating in any other line, so it’s definitely a great plus.

6. Piscifun Fluorocarbon – Best Budget

Piscifun Fluorocarbon

This line by Piscifun is an excellent option for anyone, especially beginners. It is simple and straightforward while maintaining great qualities for an affordable price. 

Of course, as a fluorocarbon line, it has superior visibility because of its water-like refractive index. So, it is almost completely invisible underwater.

Fluorocarbon Lines; The Good and the Bad

1. The Good

Element Resistance

Fluorocarbon lines are highly resistant to the effect of elements. They are not degraded by exposure to UV light rays, and they do not absorb water. These features allow them to keep their structure and integrity for more extended periods, therefore, making them highly durable.


Some people think that fluorocarbon lines do not offer stretch, which is completely wrong. The majority of fluorocarbon fishing lines are designed with adequate stretch that will allow you the back-and-forth that you would need with aggressive sea fish. 

This on-point stretch will allow you to tire out your catch. Thus, you’ll be able to reel it in quite smoothly, without snapping your line or putting in too much effort.


Fluorocarbon lines are made out of top-notch materials, which allow them to sport very low memory. Therefore, they’re less prone to tangles and coils.


This is probably the most attractive selling point of fluorocarbon lines: they become almost entirely invisible the moment they hit the water surface. Why? Because they have the same refractive index as the water, this means that they do not disturb the lights or break it in any way. 

Finicky fish that only swim in crystal clear water and know exactly what they want to feed on will be none the wiser when you hit them with a fluorocarbon fishing line.


The adequate stretch that we have spoken about before allows this line to have excellent sensitivity. No matter how light the movement is underwater, you will feel it and therefore be able to act appropriately.

2. The Bad


A fluorocarbon line has to be wet before you attempt to do any type of knot on it. Otherwise, it will simply not happen, which can be quite tiresome and time-consuming.


The strength and abrasion resistance of this line come at a cost, which is low manageability. It’s not easy to tweak fluorocarbon lines in order to make them suit you perfectly.


All of the features that come with fluorocarbon lines don’t come cheaply, as they are costlier than monofilament lines.

How to Pick a Fluorocarbon Line

1. Pound Test

This is the strength of your line. It is presented in pounds that relate to how much the line can lift out of the water. Hence, to not snap your newly purchased line, you have to know a range of the weight of your target species before deciding on a specific line.

2. Sensitivity 

Sensitivity is essential in any fishing line, and with fluorocarbon lines, you are mostly going for finicky fish that suspect everything. 

So, you’ll need to be on top of your game and to know each and every movement no matter how slight it is. Fluorocarbon lines have excellent sensitivity, and therefore they can be used for deepwater fishing.

3. Length

We have just mentioned that fluorocarbon lines can be used for deepwater fishing. Thus, if that’s your intent, you’d surely want to go for a line that comes in an abundance of yards.

4. Abrasion Resistance

PVD or polyvinylidene difluoride is a highly resilient compound, making fluorocarbon lines second to or almost as strong as braided fishing lines.

5. Diameter 

A bigger diameter means higher tensile strength. With other lines, visibility will be compromised when you go for a bigger diameter. 

However, since fluorocarbon lines are invisible underwater, you can easily increase your line diameter, therefore strength, without worrying about the fish spotting the line and making a dash for their lives.

6. Target Fishing Spot

Fluorocarbon lines are best utilized in crystal clear water or rocky waterfronts, as they are invisible underwater and have excellent abrasion resistance.

Frequently Asked Questions:

Can You Use Fluorocarbon as the Main Line?

Yes, especially that a lot of companies have designed fluorocarbon lines with copolymer cores, which are a lot more advanced than standard fluorocarbon fishing lines.

Is a Fluorocarbon Line Better than a Monofilament One?

Each one of them has its own advantages and disadvantages. Nonetheless, fluorocarbon is superior in the majority of the comparative aspects. It has unprecedented visibility, low memory, great stretch, and huge variety. 

However, if you want something a little bit easier to manage and features better knotability, then a monofilament might serve you a little bit better.

When Can I Use Fluorocarbon Line?

Fluorocarbon fishing lines can be used with any fishing type/technique. They are highly durable and almost entirely invisible.

How Often Should You Change a Fluorocarbon Line?

The expected lifespan of a fluorocarbon line is two years. Still, with proper and thorough maintenance, you can expand that. 

We would always advise you to remove your line after every fishing trip, clean, dry it thoroughly, and store it properly. Upon seeing any signs of wear and tear, try to fix them immediately.
