  • Patent number: 4384719
    Abstract: A putting device for facilitating retrieval of a golf ball during putting practice wherein a filament line is secured at one end to a golf ball and at the other end to a reel means attached to a putter. When the golf ball has been struck, the player is then free to rewind the filament line into the reel means, pulling the golf ball to its original location adjacent to the putter. The retrieval system includes a reel housed within the handle end of the club shaft. The filament line extends from the reel, downward through the club shaft, through an aperture in the striking face of the putter, and then to the golf ball.
