Yo-Zuri HD Fluorocarbon is a brand new fluorocarbon leader that maximizes the advantages of fluorocarbon and a Disappearing Pink tint. Fluorocarbon is virtually invisible in the water and red is the first color to disappear in the water column. Pink is the lightest shade of red and as a result disappears the quickest. Fluorocarbon is also only invisible until it gets nicked or scraped up. If this happens, that section of the leader actually lights up from the sunlight. The color pink added to the line helps reduce this problem keeping an anglers invisibility intact. Ultimately the combination of fluorocarbon and the color pink will double your invisibility advantage and increase your chance for hookups! Yo-Zuri HD Carbon has incredible abrasion resistance, ultimate invisibility, higher sensitivity, superior knot strength, and is a softer, more supple material than other brands.
