The Sufix Advance Fluorocarbon Line gives bass, walleye, trout, and other line-shy fish less to see while helping anglers feel subtle bites and maintain control around cover. This 100% fluorocarbon line uses Sufix Proprietary Gel Phase Technology to improve handling, performance, and clarity for techniques such as finesse fishing, jigging, drop shots, and clear-water presentations. Its high-density construction gets baits into the strike zone up to four times faster than traditional nylon, while strong abrasion resistance helps when fishing around rock, wood, and other structure. The line's natural characteristics combine with G2 Precision Winding to keep memory extremely low for smoother casts and more manageable line on the reel. 100% fluorocarbon with virtually invisible underwater performance Gel Phase Technology improves handling, performance, and clarity High sensitivity with strong abrasion resistance High-density line sinks up to 4X faster with virtually memory-free handling Test (lb.)
