Fluorocarbon lines are the most popular fishing lines used by anglers on their reels; the other three are monofilament, copolymer, and braided lines, all of which come second.

Flouro lines are notably denser and heavier than mono ones. Hence the former sink to lower depths when casting in water.

Your fluorocarbon line has many benefits over rival lines because of its low visibility. The line achieves this capability by having a reflective index close to that of water. Hence, it does not distort light.

It also has high abrasion resistance, which allows the line to perform excellently in the thickest cover and for dragging bait.

The line is also highly sensitive and transfers energy within its molecules more efficiently than other lines such as monofilaments. It also has superior toughness and high hooking power.

    How to Buy the Best Fluorocarbon Line

    photo: IanDacen

    1. Abrasion resistance

    Fluorocarbon lines are the most abrasion-resistant compared to monofilaments, braids, and copolymers. This feature is important to prevent your line from being damaged by contact with dock posts, weeds, trees, rocks, and many other hard surfaces.

    The reason fluorocarbon lines have superior abrasion resistance is their diameters, which tend to be larger than those of other lines.

    Thus, the denser you fluorocarbon line is, the higher its resistance to abrasion. Density is directly influenced by line diameter.

    Therefore, you can opt to wider-diameter lines to increase their resistance to abrasion.

    2. Strength

    The tensile strength of your fluorocarbon line is the amount of tension it can withstand before breaking. Strength is measured in pounds.

    When choosing your line, its strength will be one of the most important considerations you make because it will affect the line’s overall performance, durability, and practicality.

    If you’re fishing heavy species, it makes sense to go for a line with the high tensile strength to accommodate the load and the tension applied to it. Some lines have a maximum strength of up to 200 pounds and can handle very heavy fish without breaking.

    When fishing light species, then a low-to-moderate tensile strength will get the job done reliably. 

    3. Visibility

    Since fluorocarbon lines are significantly thicker than monofilament ones. Therefore, they tend to be more visible than monofilament lines.

    You don’t want your line to be visible in water because fish can detect it easily and avoid it altogether. Therefore, when shopping for a fluorocarbon line, look for one that is clear.

    A clear, thin line made of either 100% fluorocarbon or a fluorocarbon coating is virtually invisible to fish when immersed in water.

    4. Diameter

    The diameter of your line is critical to its performance. Diameter affects your line’s tensile strength, flexibility, and visibility.

    Very thin lines tend to have small diameters in the range of 0.12 mm to 0.018 mm. Such diameters are ideal when you want a line that is virtually invisible in water so that fish will not detect it easily.

    It is worth noting, however, that very fine line is prone to stretching. Hence, if you want a sturdy line, with low flexibility and high castability, then you can get one with a higher diameter of between 0.4 mm – 1.5 mm.

    5. Cost

    Different fluorocarbon line brands and their specifications have varying prices. Some lines are highly affordable and their base configurations will cost less than $10.

    Such low-cost lines tend to have a short length of 25 yards – 200 yards. As the line length increases to 300 yards and over, it gets pricier, according to our review.

    We discovered that fluorocarbon lines get pricier with length. Thus, you are likely to pay a lot more for a 1000 – 2000-yard line, than you would for a 100-yard one.

    Conclusion

    By ezolyzm/shutterstock

    There’s a great deal of insight about fluorocarbon lines including their different specifications and configurations, which we have covered extensively.

    When choosing the right fluorocarbon line model, remember to check its abrasion resistance, tensile strength, visibility, and diameters, to help you pick the most optimal for your fishing needs.

    The cost of your line will depend on many factors, but you can get a good quality line for about every price.
