ABSTRACT:
A device for use with a golf club which includes a mercury switch controlled which is adjustable with respect to the shaft of the club which will emit an audible sound when the club is swung rearwardly on the backswing when the preadjusted positioning of the mercury switch is obtained. In this manner the user preadjusts the position of the mercury switch controlled circuit such that the sound will be emitted when the proper backswing height is obtained. The backswing height obviously will control the distance that the ball is driven as the player advances his club forwardly into the ball. The sensitivity of the unit allows for presetting the audible emission location to accommodate putting as well as short iron golf shots. The unit includes an electrical circuit powered through a battery source and a sound emitting element all of which are controlled through a mercury switch.
