The official American Dart Organization tournament board, the Nodor SupaMatch III bristle board is ideal for players looking to maximize their scoring. The regulation-size 18-inch-diameter board offers such features as a razor-ribbon wire spider that virtually eliminates bounce-outs, a complete staple-free SupaBull II bulls-eye, an improved scoring area, and a movable number ring that prolongs the life of the board. And thanks to the super-dense sisal--which looks great and holds up to heavy use--you needn't worry about the board breaking down over time. Made to precise tournament specifications, the board measures 1.5 inches thick and is backed by a one-year warranty against defects.
