Abstract: A device for developing and testing eye-hand coordination of the kind wherein a signal is generated when a conductive loop contacts a conductive track as the loop is passed therealong. The loop has stacked lobes of varying size and is mounted at one end of an elongated handle having markings at intervals of increased distance from the loop. The track is malleable. A control circuit includes a timer which activates a signal for a predetermined time when the loop touches the track.
