From Seaguar, the inventor and world leader in fluorocarbon fishing line, comes InvizX 100% Fluorocarbon fishing line. InvizX is even stronger and has a smaller diameter than standard Seaguar Fluorocarbon line. Soft, castable and invisible to fish, Seaguar InvizX has improved tensile and knot strength, exceptional abrasion resistance, and is highly sensative. Because it sinks, Seaguar InvizX Fluorocarbon is the line to use when fishing Senko's, crankbaits or jerkbaits. Spool it up on your spinning or baitcasting reels!
