Apparatus for indicating the position of the point of impact of an object in a selected area comprises a pad (1) defining the selected area and capable of being placed in a required position, a plurality of impact sensitive devices (2) distributed within the pad, and means associated with each impact sensitive device for generating an output signal when the device is impacted by an object (7). Preferably the pad (1) is portable. Applications include sports such as cricket, where the device could be used to test bowling accuracy. |
