RELATING TO TARGET APPARATUS |
摘要 |
A target for projectiles, such as darts, has a base and a multi-section board mounted on the base and rotatable to any of a number of set positions. One or more sensors, concealed behind the board, determine the orientation of the board and produce a signal which is fed into the computerized scoring system, keeping that consistent whatever the orientation of the board.
