Abstract
A putting aid includes a clamp for mounting the putting aid on the shaft of a putter and a dotted line projector mounted on the clamp for adjustment relative to the contact surface of the putter so that the dotted line is projected perpendicular to the contact surface. The dotted line projector includes a bright light source, such as a laser diode, a power source and the necessary optical elements to generate and project a line of dots on the putting surface extending generally perpendicular to the putter clubface. In one embodiment, the dots are equally spaced apart so that the distance of the backswing can be gauged by observing the number of dots that pass over the surface of the ball during the backswing. In one embodiment the putting aid includes a mounting ball secured to the clamp, and the housing further includes a housing clamp adapted to be releasably secured on the mounting ball to allow simultaneous positioning of the projector about two or more axes.
