Abstract: A forearm mounted wrist position training device for signaling a golfer when his or her wrists bend improperly during a golf swing. A housing is secured to a forearm with a sensor pad engaging the back of the hand. The pad position can be varied to fit the forearm and wrist position when the golfer addresses the ball. The pad is mounted on one end of a sensor lever with an attachment device attached to the other. An actuator lever is fastened to the attachment device, with the other end pivotally mounted in the housing adjacent to a switch. When the golfer bends his or her wrist beyond a selected limit, the actuator lever will close the switch which will then activate a battery powered circuit to produce a signal such as an audible beep. The training device can be placed on either wrist and is useful with putters and other clubs. The golfer will learn to hold his wrists in the proper position by avoiding causing the signal to sound.
