Power Carbon is a brand new fluorocarbon that has improved attributes in every area. Power Carbon has higher knot strength, better over all strength, and improved clarity even when nicked or chaffed. Power Carbon does not turn cloudy, even in saltwater, or transfer light thru nicked areas like most other fluorocarbons. A lower refractive index makes Power Carbon closer to the refractive index of water, which in turn makes more invisible under water. This next generation leader material is more supple and handles better then other fluorocarbons, which makes knot tying easier. With its higher density it is more sensitive and has a faster sink rate. All of these features make Yo-Zuri Power Carbon the new Super Fluorocarbon. Power Carbon is available in clear and the put ups are 30 yard spools in line test from 4# - 200#.
