Well-balanced and extremely strong 100% fluorocarbon line

It is slightly weaker than nylon in terms of strength, but it is particularly durable, with excellent resistance to scratches, scuffs, and abrasion, and has no water absorption (0%), so it does not deteriorate in water. It sinks quickly with a specific gravity of 1.78 (nylon 1.14 / ester 1.38). Its refractive index is 1.42, close to water’s 1.33 (nylon 1.53 / ester 1.60), making the line difficult to see underwater, and it can be connected together and stored compactly thanks to the use of ultra-thin connecting spools.
