Flouro carbon line

Best Fluorocarbon Fishing Line For Your Reel (2021 Review)

When I first heard of fluorocarbon line, also known as fluoro, I felt like it was a godsend. Too many times in my early fishing life I felt I did not have the proper line on for my fishing technique.

So when I found out it was practically invisible underwater I immediately bought some.

It made a huge difference when fishing in clear water and in suburban lakes where the fish are noticeably more skittish.

On top of being invisible, it has many other features too, but we’re going to go more into depth on that down below.

So, if you’re interested in picking up some fluoro line then check out the information below. On top of that, we’re also going to go over five different types of fluoro line that you can use on your next time out on the lake.

Those items are:

First, let’s go into more depth on fluoro line and what its uses are.

What is Fluorocarbon Line?

If you looked at monofilament line and fluoro right next to each other you might not be able to tell much of a difference. Especially if both lines were clear colored. But below the surface, they couldn’t be more different.

Fluoro is much denser than mono, which means it will not float and sinks once it is in the water. Ideal for sinking lures but not for topwater or anything you want suspended in the water column.

Overall, fluoro is made up of a broad family of different compounds. In the world of fishing, you’ll also hear it be called polyvinylidene difluoride. Or it could be PVFD for short.

Basically you can throw just about whatever you want with fluorocarbon. From crankbaits to jigs, and soft plastics.

Features of Fluoro Line

Below, we’re going to go over all of the different features that make fluoro unique from mono, braided line, and other lines out there. Most of these will help your fishing, but some only work for certain techniques.


As we mentioned earlier, fluoro is basically invisible once it is in the water. The reason for this is because it does not distort the light that is passing through the water.

This is because it nearly has the same refractive index qualities as water.

This means that if you’re ever fishing in clear water then you should have at least one spinning reel with fluoro tied on. This is especially true if the fish are skittish, or if you’re fishing a heavily pressured body of water.

Abrasion Resistance

Because fluoro is so difficult to see underwater, that means you can use a heavier line. This gives you confidence knowing that if you need to you can really pull out a big fish if you wind up hooking into one.

On top of that, the abrasion resistance is top-notch. If you’re fishing a spot where braid would be best but the water is too clear, then fluoro is going to be your best bet.

Throw jigs in tight cover or drag lures along the bottom without fear.


Fluoro is way more sensitive than monofilament line. That is because the tightly packed molecules in fluoro line transmit more energy. This sends more information from the end of your line back to you at the reel.

This sensitivity allows you to detect light bites, as well as what the bottom of the lake or river is made of.

It also sinks at a much faster rate than mono, meaning that there will be less slack line between the rod tip and line in the water.

Low Stretch

Fluoro has little to no stretch to it. So you get a great hook set on a fish, even when you hook up with one from a long way away. So if you have been having trouble with getting solid hooksets on your monoline, then switching to fluoro might help you out.

With this low stretch, you also get a very poor shock strength. A line with good shock strength means that the line will not snap under sudden pressure.

So, if you’re using light fluoro then you have a greater chance of breaking off your line. If you need to use light fluoro then try keeping your drag loose to help combat this.

When to use Fluorocarbon line

Many of us don’t have the opportunity to fish unpressured lakes. So, if you’re looking for an edge that could make the difference between a full live-well and a day of getting skunked then fluoro could be just the thing that pushes you over the top.

Skittish fish in public lakes near cities get tons of pressure, and it can be very difficult to consistently catch fish on. So, a strong, sensitive, and nearly invisible line would be something that could help you out.

When dragging a Carolina rig along the bottom of the lake, the fish won’t be spooked by your green mono. Instead, they’ll see the lure only and will increase your number of hookups.

If you want to fish deep then fluoro is going to help keep your lure down deep in the strike zone. Since it sinks you don’t have to worry about the line halting the fall of your lure, or making it rise up unexpectedly.

Fluoro is especially deadly if you’re going after skittish fish, in clear water, near abrasive structure on the bottom of the river or lake.

Trolling around and pitching soft plastic around docks, lily pads, cypress stumps, and other submerged surfaces will get you a lot of fish.

Different ways to use Fluorocarbon

If you don’t want to spool your reel with fluorocarbon then you could easily use it as a fluorocarbon leader line instead. Many people enjoy the strength of braid but don’t like how easy it is for fish to see. A way you can get around this is to use a fluorocarbon leader material.

Depending on what you’re comfortable with you should be attaching 5-20 inches of leader to your line. This will give you enough space so the fish won’t be spooked by the braid.

If you go the 20-inch route then that also gives you some wiggle room to cut away and tie on new lures without having to tie on a new leader every single time.

What else to Look for When Purchasing Fluorocarbon Line

If you plan on only using fluoro as a leader then you don’t need to purchase hundreds of yards of line. Finding a spool that holds 50 yards will keep you going for several seasons.

If you do plan on using it for your whole spool then a package of 200 yards or more would be ideal.

If you do plan on using fluoro as a leader then there are a few knots that you should learn to ensure the knot is strong.

Alberto Knot

If you want to connect braid to fluoro then the Alberto Knot is going to be the best to use. This knot was designed especially for connecting lines of different diameters as well as material. It’s important to use this knot when tying fluoro to braid because the braid is so strong that it can actually cut the knot. Alberto does not allow this to happen.

Double Uni Knot

The Alberto can also be used to connect mono to fluoro, but if you want to learn an even stronger knot for a fluoro to braid connection then you should learn the Double Uni. This is a very easy knot to remember and has a strength of 85%-90%
