Abstract: A laser aiming system and method is provided for determining the aiming tendencies of an individual golfer during putting. The system consists of two main parts. One of these parts is a housing with a laser in it for directing a beam of light parallel to the putting surface and at right angles to an imaginary line between a ball to be putted and a target hole. A mirror attached to the toe of the putter head is oriented perpendicular to the ball-striking surface of the putter head. The location of the laser beam is such that when the putter is in position to strike the ball, the projected beam of light is reflected from the mirror on the putter head back to the housing from which the laser beam is projected. The reflected beam strikes a 45° inclined mirror in the housing and reflects upwardly to an opaque indicating window, where the reflected laser beam spot is visible to the golfer. When the putter is correctly aimed, the spot is in the center of the window.
