Developed with Seaguar's exclusive, proprietary Double Structure Technology, Grand Max Tippets are sensitive and soft. Double Structure Technology provides two different flusrocarbon resins, precisely extruded as one solid piece, for a fluorocarbon leader that offers both strength and sensitivity. As with all 100% Fluorocarbon products, Grand Max Tippets are much less visible underwater than monofilament line and virtually invisible to fish. Grand Max is also UV resistant, chemical resistant, non-absorbant, high density and imperious to cold conditions.
