Abstract: A method for determining the directional aiming tendencies of an individual golfer using a laser sighting device which includes a body portion having a flat end surface on one end and a pointer on its opposite end. Underneath the body portion is a laser light assembly. The golfer positions his/her putter to direct a golf ball toward a hole. Once the ball strike face of the putter is aligned to the golfer's satisfaction, the golf ball is replaced with the laser sighting device. The flat surface of the device is placed flush against the ball-striking face of the putter. The device is turned on, projecting a laser light from the pointer to the golf hole. The laser light provides an indication of whether a golfer is aiming to the left or to the right of a target line between the position of the golf ball and a hole or simulated hole.
