Abstract

The critical features of the improved putting stroke training device of the present invention includes a Y-axis sensor means using a convertor for converting mechanical energy to electric energy for detecting and signalling whether the face of a putter strikes a golf ball perpendicular to the path of the putter head and X-axis sensor means for detecting and signalling any abnormal acceleration or deceleration of the putter head. The Y-axis sensor means is disposed in a Y plane that is perpendicular to the golf ball striking face. The X-axis sensor means is disposed in an X plane that is perpendicular to the Y plane and is in the same plane as the shaft. This putting stroke trainer will assist the golfer in striking the ball with the club face perpendicular to the path of the putter head, and in developing a smooth pendulum swing and avoiding the "yips".
