Yo-Zuri HD Fluorocarbon is a fluorocarbon leader that maximizes the advantages of fluorocarbon with a clear tint. Fluorocarbon is virtually invisible in the water until it gets nicked or scraped up. If this happens, that section of the leader actually lights up from the sunlight. The clear line helps reduce this problem keeping an angler?s presentation as natural as possible. Yo-Zuri HD Carbon has incredible abrasion resistance, ultimate invisibility, higher sensitivity, superior knot strength, and is a softer, suppler leader material than other fluorocarbons on the market.
