  • Publication number: 20170203182
    Abstract: Disclosed is a golf putter incorporating a training device that is configured to provide an intuitive coaching system to aid a golfer in the development of proper visualization of their putt, and that provides a configuration that ensures that the golfer maintain proper form (including through ensuring proper alignment, proper backswing, and proper topspin application) throughout their practice putting strokes. The golf putter includes a motion sensor that determines and preferably displays to the golfer the speed of their putting stroke and the distance of that stroke through both rearward (backstroke) and forward (throughstroke) movements, and provides a light beam projection device configured to project a tracking pathway onto the ground in front of the putter, indicating the ball path that the putter should strive to putt the ball through with their stroke while insuring proper alignment of the putter face with the intended target line.
