High-definition printing creates distinctive shades of blue and green you won't see on other dartboards. The staple-free bull's-eye reduces bounce outs, ensuring more accurate scoring. Galvanized triangular spider wire adds superior durability and strength to extend the life of the board. Since the wires have a triangular shape, they reduce the chance of bounce outs. Detach and rotate the movable number ring to give fibers time to heal. Tournament-regulation 18""-dia. face accommodates steel-tip and soft-tip darts.
