The Best Situations to Use Fluorocarbon Fishing Line

When shopping for fishing line types, your three basic options are braided line, monofilament, and fluorocarbon line. You’re thinking of buying a fluorocarbon line, but you’ve only dabbled with it in the past. What situations call for fluorocarbon?

Fluorocarbon fishing line is more elastic and invisible, so use it when you don’t want fish to see your line. The stretch of fluorocarbon makes it a good candidate when fishing with swimbaits, jigs, chatterbaits, jerkbaits, and/or crankbaits. 

Ahead, we’ll elaborate further on what comprises fluorocarbon fishing lines and their properties so you can determine which situations it’s most appropriate to reach for this type of fishing line. Make sure you keep reading, as we have lots of exceptional information to share ahead! 

What Is Fluorocarbon Fishing Line?

First, we want to begin with some information on fluorocarbon fishing lines so you can understand fully the type of fishing line you’ll be working with. 

Fluorocarbon leaders are made from a chemical polymer. It’s that polymer where most of this fishing line’s traits are derived from. Let’s take a closer look at those traits now.

Higher Energy Transmittance 

The polymers contain a group of molecules that are packed very tightly together. When fishing with a fluorocarbon line, this lends you the ability to increase your rate of energy transmittance, especially over a monofilament line.

What does energy transmittance have to do with fishing, you ask? Quite a lot, actually! The higher the rate of energy transmittance your fishing leader is capable of, the greater the quantity of information sent from one end of your fishing line to another.

This then clues you in about whether your artificial lure or live bait has hit the bottom of the water. You can also usually detect line activity such as bites, even subtle ones, more so than when fishing with other types of line.


Most fishing line isn’t cheap, so when you spend your hard-earned money, you want to ensure that your line is going to go longer. When it comes to fluorocarbon fishing lines, there’s less risk of the line falling apart on you after a few days of fishing.

The polymers in fluorocarbon prevent deterioration and damage of all kinds. Battery acid, gasoline, and sunlight won’t degrade it, and insects aren’t likely to want to snack on your line either.

Stretch + Sensitivity 

One of the primary traits of a fluorocarbon fishing line is its stretch. Fluorocarbon is not as stretchy as a monofilament line, but it does have a good amount of elasticity. That in turn increases the sensitivity of the line. 

Won’t Absorb Water

If you’re fishing with artificial lures and you’re trying out a technique with a jig or a spinnerbait to get the fish biting, nothing is worse than when your fishing line feels like a thick, heavy rope. This happens because your line absorbs water and gets progressively heavier as the day goes on.

Not with fluorocarbon fishing line! The polymers prevent water absorption in large quantities. The line will retain its weight all day long so you can wait until you’re wrapping up your trip to pull out that big fishing technique. 


Many materials have a refractive index, which refers to the degree of light bending as it passes through water or another substance. The refractive index of the fluorocarbon fishing line is practically the same as water.

What does this mean for you, the angler? When you fish with a fluorocarbon fishing line, it looks nearly invisible once it’s in the water. It’s not only you who can barely see the line, but the fish as well. 

When Should You Use Fluorocarbon Fishing Line?

In any fishing situation, there are instances when you want a specific type of fishing line. This section will outline, per the info in the intro, which scenarios you should use fluorocarbon fishing line specifically. 

When You Want Your Line to Look Invisible

Has it been a rough day of fishing so far because nothing is biting? It might be time to switch to a fluorocarbon fishing line. The clarity of the line creates a nearly invisible effect in the water. Fish won’t be able to see your line, so they’ll be less reluctant to bite on an artificial lure or live bait. 

When Fishing in Clear Freshwaters or Saltwaters

The clarity of the water matters a lot in determining the invisibility of a fluorocarbon fishing line. In murky waters, even a fluorocarbon fishing line is going to be noticeable. 

However, in clear freshwaters and saltwaters, using a fluorocarbon fishing line can help you reel in more trout, catfish, carp, and similar species. You could end up with a cooler full of sizable fish so you’ll have dinner options for a long time to come! 

When Hooking Powerful Fish

The stretchiness of fluorocarbon fishing line increases power absorption, especially when casting and retrieving fish in open water. If you’ve used other types of fishing line for heavyweight fish species and had the line snap on you, fluorocarbon should fare better. 

When Freshwater Fishing with Artificial Lures

The stretch of fluorocarbon fishing line also benefits anglers in that you can mimic the action of live bait using artificial lures quite effectively. From swimbaits to jigs, chatterbaits, jerkbaits, and crankbaits, these lures will become your new best friend for catching bass and more!

Stren FluoroCast Fluorocarbon Fishing Line 

The last fluorocarbon fishing line recommendation on our list but certainly not the least is the Stren FluoroCast line

Final Thoughts 

Fluorocarbon fishing line is moderately stretchable, highly sensitive, and strong. Its best quality is that it turns invisible when in clear water, yet the fluorocarbon line won’t fill with water so it drags around in the lake or sea. 

Now that you know which situations call for fluorocarbon, you could taste more fishing successes. Good luck!
