Most boards just let you throw. This one helps you practice. Movable training targets let you work any spot on the face, so you can drill the segment that keeps costing you games, and printed diamonds on the doubles and trebles give your eye something to lock onto. The razor-thin, staple-free wire leaves as much of the face as possible open for scoring. The number ring lifts off and rotates, so wear spreads evenly instead of hollowing out one busy corner of the board.
