Seaguar InvizX Fluorocarbon Line gives freshwater anglers a soft, castable fluorocarbon mainline for skipping docks for largemouth, dragging tubes for smallmouth, or running live bait for walleye, using exclusive 100% Seaguar resins that keep the line supple with extremely low memory on both spinning and casting reels. InvizX stays virtually invisible underwater in clear water situations, sinks fast to stay in the strike zone, and delivers reliable hook-setting power with abrasion resistance around rock and timber. The smooth handling lets anglers fish fluorocarbon all day as a mainline across multi-species tactics without the stiffness common in other fluoro options.
