Yo-Zuri H.D. Carbon Fluorocarbon Leader is constructed of HD Carbon, a revolutionary new fluorocarbon leader that enhances the advantages of fluorocarbon by matching it with a Clear and "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, chafed, or scraped up. If this happens, that section of the leader actually lights up from the sunlight. However, since Yo-Zuri's new HD Fluorocarbon is tinted pink, this problem is eliminated and your leader remains invisible! Ultimately this combination will double your invisibility advantage and increase your chance for hookups! Yo-Zuri HD Carbon has incredible abrasion resistance, ultimately invisibility, higher sensitivity, superior knot strength, and is softer, more supple material than other brands of fluorocarbon. Available in 30YD spools, 100YD spools and 100YD coils.
