Abstract

Abstract First and second arrays of photoelectric units respectively delineate the vertically inclined plane and the arcuate paths traveled by the clubhead during a full golf swing, and through associated electrical circuitry cause actuation of signaling devices upon the performance of an improper swing by the golfer. The signaling devices give immediate audible notification of an error in a golf swing, and also indicate the approximate location of the error or errors. The photoelectric units are physically spaced from the golfer so as to not impede his natural swing, and are adjustably movable and selectively energizible so as to readily permit use of the apparatus by golfers who differ in size and/or in other physical characteristics, and so as to permit, if desired, the use of progressive teaching techniques.
