Best Fluorocarbon Fishing Line Review and Top 3

best fluorocarbon line guide

If you are chasing fish that spook easily or fishing very clear water then you are going to need to fish with fluorocarbon line - at least as your leader anyway.

The near invisibility of this line in the water is what makes or breaks your fishing trip. Yes, sure you may be using a heavy duty or even braided fishing line as your main line but you are definitely going to want to top it off with fluorocarbon line to the hook and bait.

We fish with braided line most of the time and we would never even consider attaching our lures directly to this because you will absolutely spook the fish. Instead we attach a length of fluorocarbon line - at least a rods length to the braid and then attack our lures to the other end.

Yes the are a plenty of options when it comes to fluro line and each serves a purpose but today we want to concentrate on the best fluorocarbon line on the market and why it should be your next purchase before you cast another lure into the water.

You are trying to present your bait to the fish in the most natural way possible and because the line almost disappears in the water the bait or lure looks as if it is swimming freely.

What is Fluorocarbon line anyway?

Essentially it is a plastic compound that is extruded into a very thin strong and abrasion resistant line used for fishing. Some may say it's really only any good for using as leader line. That may have been the case in the past but like everything things have moved on and the quality of modern fluorocarbon fishing line gives you plenty of options when on the water.

​Some of benefits of using fluorocarbon line are that it has exceptional abrasion resistance. This is great if you are fishing in rough patches with rocks etc or have a fish on with a nasty set of knashers in it's mouth. 

It's low stretch so you can feel the more sensitive bites - pair this up with a braided mainline and nothing will go unnoticed. With this straight through power setting a hook is much easier that using line that stretches and gives way to any sort of force.

If you are fishing in very clear water then you are going to love the fact that fluorocarbon line is almost invisible underwater​. It is also more dense than other line types so will sink faster after you cast it. This is great for getting you bait or lures down into the swim but not if you are trying to delicately land a dry fly on the surface film of the water when trout fishing...

It is also chemical resistant. If like me you are a favorite meal for any bugs flying about on a warm day you will have lathered yourself with repellant. ​Some traditional lines would absorb these and deteriorate rapidly. No such worry with fluoro.

What is Fluorocarbon line used for?

As mentioned above, traditionally fluorocarbon line would have been used for leader lines but now with the high quality lines out there you can use it straight through from reel to bait. Make sure you are using the correct line test on your reel though as due to line memory etc.. you may end up with a mess on your reel.

We mainly use this type of line for leaders. It's near invisibility in the water is great when chasing nervous fish or when you are flipping lures into a very clear stream or lake. ​Because the line is completely water resistant (unlike monofilament line) it never looses it's strength in the water. Also the fact that it is 100% UV resistant you wont suffer any degrading in line strength on a warm sunny day.

Best knots for Fluorocarbon line

One thing to make sure you always do when using fluorocarbon line is to moisten you line when tying knots. If you want a super snug and tight knot then always wet the knot first.

For tying fluorocarbon line to a swivel you should definitely use the improved clinch knot. This super strong knot will never let you down.

If you are trying to join a fluorocarbon leader to your main line then you could use a double uni knot. Again a super strong knot that will last all day if tied correctly.

The best knot for tying your fluoro to a lure or hook is the 'Kreh Loop Knot'. This particular knot won the best knot category on the Saltstrong website.

Some people (I used to be one of the) often wonder why you would use a loop knot to tie you hook to your leader and not a standard uni knot. Well the best answer I can give you is that this type of knot gives you bait more freedom to float about unrestricted and can have a huge impact on strike rate when fishing. Check out the video below to find out how to tie this knot and give it a go next time you are out.

We could spend all day looking at multiple option but to be honest we'd rather be out fishing. Top choice is Seageur InvizX followed by PLine which is the softest fluorocarbon line. Kastking takes out the best value fluorocarbon line even though it's technically not 100% fluorocarbon.

That's it for this review of the best fluorocarbon line. Have you a line that you fish with all the time?
