What is Fluorocarbon? 

Fluorocarbon is an organofluorine compound that consists of carbon and fluorine and is used in the construction of everything from nonstick frying pans to anesthetics. Various industries have used fluorocarbon to create tons of products, but it was not until the past decade or so that fluorocarbon has gotten recognition as a premier fishing line for anglers. For years anglers were stuck using monofilament as their main fishing line until about the 1990s when some of the first fluorocarbons were introduced to the US market. Over time manufacturers began to figure out how to make fluorocarbons more angler friendly, and now it's nearly impossible to go to any outdoor retailer without seeing 50 different varieties of fluorocarbons on the shelf. This has only been to the advantage of the fishing industry, because now we have a line that is nearly invisible to fish, highly-sensitive, and keeps your bait in the strike zone longer.

Why do you need Finatic Fluorocarbon?


Fluorocarbon has a low light refraction index. Much like water, this makes fluorocarbon virtually invisible to fish.  For example, fluorocarbon has a 1.41 refractive index and water has a 1.33 refractive index, making the clear line nearly indistinguishable from the water. The other key factor when using fluorocarbon is that you are able to upsize your line capacity when fishing heavy cover techniques.  If you are flipping a thick Tully patch and not getting the bites on straight braid, try tying on a 25lb Finatic Pro Series Fluorocarbon leader and you will get those weary fish to bite and you can pull them out of cover.  Because the line is nearly invisible, you'll get a few more bites than if you were using straight braid or monofilament.


Because fluorocarbon molecules are more tightly packed, they have a good connectivity rate, allowing you to detect the subtlest of bites. It's a common myth that fluorocarbon does not stretch. However, this is not the case. It does stretch, but it takes a lot more force to do so then its monofilament counterparts because of its higher molecular density. Because the molecules in fluorocarbon are so tightly packed, they enhance your ability to sense any pressure changes and identify the source whether its rock, wood, weeds, or bites. 



The density of Fluorocarbon in much greater then monofilament or braid and twice as dense as water. This makes fluorocarbon great for a wide variety of techniques because the line sinks and keeps baits like crankbaits and senkos in deeper strike zones longer. Here on the West Coast, we take full advantage of the fluorocarbon's tendency to sink fast while fishing weightless worms or other finely tuned techniques.This gets light baits down in a reasonable time period. If you want to get your reaction baits deeper in the strike zone try going down on lb test size. Typically the lighter the pound test the deeper your line and bait will run.


There's a reason there are 14 different golf clubs in your golf bag...

Just like most things, all fluorocarbons are not made the same or for the same applications. Some fluorocarbons stretch and are very soft, remaining limp throughout the line's life cycle. While others are very rigid, requiring a lot more force to stretch, and are better for heavy cover situations and aggressive game fish.

Soft, Supple Fluorocarbons

If you ever went to cast on a spinning rod with fluorocarbon and had the rat's nest come out the other end, ruining part of your fishing day, then you were probably not using a soft and supple fluorocarbon. Unlike what was described above, soft fluorocarbons are very limp and smooth and react well on the spool. Our version of this line is the Finatic Pro Series Fluorocarbon Fishing Line. This is the line that can cast a mile and is great for a variety of tactics from light cover bottom fishings to reaction techniques.

Rigid Shock Fluorocarbons

Harder more rigid fluorocarbons are built for harsher situations and for stronger and more aggressive fish. These fluorocarbons like the Finatic Pro Series Leader are not meant to be spooled on a reel but are used in 2ft to 9ft leader sections connected to braid or mono. The resins in these lines are a lot more rigid, very strong, and abrasion-resistant. Ridgid fluorocarbons are usually categorized as shock leaders because they do just that, absorbing the shock from powerful hook sets and aggressive bites that large gamefish inflict on an angler's line.
