Abstract
Abstract The top surface of a golf club head includes a first lens adjacent the striking face and a second lens adjacent the rear of the club head. A small battery-energized light bulb is positioned below the first lens. The second lens is located in the remote end of a light transmitting cylinder which has its other end positioned adjacent the light bulb. The light transmitting cylinder is mounted so that it may be moved to various positions along an arcuate path generally parallel to the rear surface of the club head. The light beam transmitted upwardly by each lens may be used by a golfer to provide information relating to the position of the club striking face during practice swings. The sole plate of the club head is removably mounted to permit the weight of the club head to be varied. To permit access into the interior of the club head, the head is made in two parts, the upper one of which is bolted to the lower part.
