Abstract: A putting training device for improving consistency of body position, putter path, putter face angle, and timing during a putting stroke. A body alignment target within a putter data module helps position the golfer's head directly over the ball for shoulder joint consistently relative to the ball. A magnet is securable to the C.G. of the putter head which is tracked by sensors within the module to help insure that the putter travels in a straight line on approach to ball strike. Optical sensors determine the putter face angle at ball impact. A metronome is also provided to practice swing timing. An end-of-swing delay indicator helps to hold the golfer's body in the correct position until the follow-through is complete. A series of lights and tones provides feedback indicating putter path to the ball and the putter face angle at ball impact.
