发明名称 Golf swing trainer
摘要 A golf swing training device comprised of a grip, a foreshortened shaft and a hollow head. The head contains a battery activated by a switch also located within the head, to illuminate a lamp, also within the head. The lamp emits a beam of light downward to the ground and forward of the club head. The light beam permits the golfer to trace the arc of light corresponding to the golfer's swing to impart a mental image to the golfer of the precise club head path. The device also comprises a linear guide strip which is placed on the ground in front of the golfer to establish the desired club head path. The golfer preferably follows the path of the light beam during a swing and compares the light path to the guide strip.
