  • Patent number: 4997189
    Abstract: A method of teaching and learning putting, via accurate visual feedback, and employing a putter head having a light reflective surface, a golf ball zone, a light beam generator, a beam target surface, and a local (cup) zone toward which a putter struck ball travels on a putting surface, the steps that include: locating the putter head directly behind the ball zone on the putting surface; operating the generator to direct a light beam at the putter for reflection by the putter, or by a face carried by the putter, toward the target surface to impinge thereon at an impingement locus; and swinging the putter in a manner to strike a ball at the ball zone and stroke it toward the local (cup) zone, thereby causing the impingement locus of the reflected beam to trace a detectable travel pattern providing indication as to whether or not correct putter alignment forces would be applied to a struck ball to cause it to travel to the local (cup) zone.
