Abstract
A golf putting stroke trainer including an inertial sensor. The sensor is responsive to axial rotation and push-pull movement of the club face. The sensor is disposed in electrical communication with an alarm circuit. The trainer is positioned within a standard grip on the shaft of a putting club and provides a user-detectable signal if, during a putting stroke, the putter is rotated around the longitudinal axis of the shaft of the putter or moves in a direction parallel to the plane of the club face.
