WHEN IT COMES TO BIG FISH, SEAGUAR SHOULD BE YOUR CHOICE!!! SEAGUAR invented Fluorocarbon Leaders and Line in 1971 and has been progressing and improving upon the process ever since. Our most advanced leader brand, Fluoro Premier Big Game has 42% more knot strength than leading fluorocarbon competitors. Fluoro Premier has smaller diameters and increased strength vs. our FC and Red Label brand leaders. Fluoro Premier offers incredible knot and tensile strength and is an extremely soft line with low memory. Ideal for larger species in fresh or salt water. As with all 100% Fluorocarbon products, Fluoro Premier Leader is much less visible underwater than monofilament line and virtually invisible to fish. Fluoro Premier is also UV resistant, chemical resistant, non-absorbant, high-density and impervious to cold conditions. Made from 100% Seaguar resins and produced using our proprietary extrusion process.
