Abstract: An apparatus and method for teaching golfers proper putting fundementals. The apparatus comprises a device which removably mounts over a putter head, projecting a laser beam on the plane perpendicular to the striking face of a putter just over the sweet spot. The apparatus also includes a means for the golfer to properly align the eyes vertically above the striking face. The laser beam is directed towards and on a linearly calibrated target strip. By directing a shot at various positions on the target strip while viewing the putter from a proper vertically aligned position, a golfer is able to learn to judge putting situations.
