Abstract
A golf putting stroke trainer includes an inertial sensor responsive to axial rotation disposed in electrical communication with an alarm circuit. The trainer is positioned within a standard 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.
