The Viper Aim 360 Sisal Dartboard uses compressed sisal fibers that self-heal, returning to their original shape. It lasts years longer than wood or paper dartboards. The staple-free bull's-eye reduces bounce-outs, ensuring more accurate scoring. Razor-thin spider wire further reduces the chance of bounce-outs. Detach and rotate the movable number ring to give fibers time to heal. High-resolution focus diamonds in the doubles and triple rings give you a spot to hone in on. The tournament regulation 18""-dia. face accommodates both steel-tip and soft-tip darts. Includes easy-mount hardware and game manual.Manufacturer model #: 42-6008.
