ABSTRACT:
A golf practice device with a platform for the golfer to stand on rotatably mounted on a base with interengaging stops on the platform and base for allowing only a small angle of movement therebetween. An adjustable tension spring extends below the base and platform to provide a preselected force against rotation. By the golfer standing on the platform and swinging a club, the proper torque is created at the start of the downswing if the platform rotates overcoming the spring tension. In one form an electrical circuit provides an audible or visual indication of that rotation.
