ABSTRACT:
A golf training device is provided that includes an attitude sensor, audible alarm, a power source, and associated electrical circuitry, all contained in a relatively small rotatable cylindrical enclosure. The device senses the orientation of the head of the golfer such that when the vertical axis of the golfer's head is coincident with a vertical orientation, a sensing device assumes a first state while otherwise the sensing device assumes a second state;
A timing device is connected with the sensing device such that as long as the sensing device assumes the first state, the timing device is inactive, while when the sensing device assumes the second state, a timing period is initiated, continuing until the timing period is completed, unless the sensing device again assumes the first state before the completion of the timing period whereupon the timing device again is inactive until the next incident when the sensing device assumes the second state;
An audible alarm is connected to the timing device, the alarm producing an alarm signal in response to the completion of the timing period; and the sensing device is mounted to move with the head of the golfer during the golf swing; whereby the timing period may be set such that minor movement of the head of the golfer which causes the vertical axis of the golfer's head to move out of the vertical orientation does not produce an alarm signal while a premature tilt of the head of the golfer greater than said minor movement during the golf swing will produce an alarm signal.
