Abstract
Abstract This invention is a golf player's cap fitted with an electrical circuit; the circuit including a microphone, an audible alarm, a momentum switch and an inhibitor switch. If the golfer's head is moved during the club swing and before the ball is struck, the momentum switch closes for an instant and the alarm sounds for two to three seconds. If the golf ball is struck before the golfer's head is moved, the microphone, which is aimed at the golf ball to be struck, picks up the sound of the golf club striking the ball and actuates the inhibitor switch, which prevents the alarm from being sounded.
