The Scientific Anglers Freshwater Tippet 100 Meter Guide Spool's redesigned tippet spool makes your freshwater fly fishing life a whole lot easier. This 100 meter tippet spool features an independent, free wheeling hub to allow the tippet spool to spin freely when joined together. In addition, the hub can be retracted to become flush with the spool body when used alone or with other tippet spools on the market. TheFreshwater Tippet 100 consists of a clear copolymer freshwater line that provides excellent knot strength, high abrasion resistance, and low memory. To avoid confusion, Scientific Anglers gave each size tippet a color coded tippet retainer band that has the size of the material printed on it so you know what you're reaching for. A water resistant label prevents cracking and peeling, and all spools are molded with UV inhibitors to help protect the tippet from UV rays. In addition, each spool features a built in razor to cut the material right where you want it.
