Abstract
The spinning target assembly comprises a pair of posts and a bridge therebetween. Three spinning target units hang downwardly from the bridge. The units move back and forth between the posts. Each unit includes a pair of supports and a target therebetween rotatably carried thereby. Two Hall-effect devices are mounted in each support and a magnet is mounted in the spinning target, whereby the Hall-effect devices can sense the direction and number of revolutions of the target.
