  • Patent number: 5640777
    Abstract: An alignment system and method of use provide significant improvement in the accuracy of a golf stroke or putt. The alignment system may be incorporated into or attached to the head or shaft of a golf club such as a putter or a chipper. One component of the alignment system is a sighting alignment system which includes a turning mirror that is attached to the club head or shaft or may be integral to the top or rear portion of the golf club head. While viewing the reflection of the ball and target through the mirror, the golfer obtains visual feed-back that is very sensitive to club positioning and aiming. The other component is another optical alignment system in which parallax is removed to put the golfer's eye in the proper plane to assure alignment over the golf club head. When both alignments are maintained in the reflected image during the golfer's stroke, the accuracy of the stroke is dramatically improved.
