摘要:
A dart target includes a plurality of electrically conductive scoring beds. An aerial is spaced from the beds by a separation of the order of magnitude of the size of the target. A transmitter and receiver are connected to the aerial and beds. When an electrically conductive dart is imbedded in one of the beds it receives a signal from the aerial which enables determination of which bed the dart is imbedded in. The spacing of the aerial results in more or less uniform signal strength at the dart regardless of its location in the target.
