  • Patent number: 4577868
    Abstract: A golf swing practice device comprises a pair of sensors for detecting the golfer's weight placed on address plates, a first circuit having a memory element for recording the proper weight shift during the course of a golf swing, and a second circuit having two sound generating elements providing output signals to generate three successive advising sounds from a chime. The interval of time between the generation of the first and second sounds may be adjusted by a regulator whereby the golfer may take the proper timing when initiating the downswing at the completion of the backswing. Further, the three successive sounds may be generated from a chime connected to the second circuit.
