Seaguar Tatsu is an amazingly supple, fluorocarbon line that offers extraordinary knot strength, exceptional castability, and Seaguar's state-of-the-art Double Structure construction process. Created from two custom, 100% fluorocarbon resins, Tatsu has a softer exterior resin which enhances knot strength and a high-density interior resin that improves tensile strength. The innovative Double Structure process results in a high-performance fluorocarbon line that offers anglers tremendous application flexibility. Tatsu can be spooled on spinning and baitcast reels as a mainline, tied to braid as an inshore top shot and as a premium leader material. Plus, Tatsu also features Seaguar's Level Wind Technology which spools the line by laying it down side-by-side with no crossover to ensure maximum line strength without line stress or twist.
