Patent ID: 7938733

Claim:
A golf swing training device for use with a golf club, comprising: a. an illuminator mounted on an upper end of the shaft of the golf club, said illuminator producing a beam of light wave energy directed away from the golf club along a path which is generally coincident with a longitudinal axis of the club shaft; and, b. a detector assembly including a light sensor and a transducer, said light sensor being sensitive to said beam produced by said illuminator and outputting an electrical signal in response thereto, said light sensor being worn by the golfer and strategically located around the stomach region of the golfer to define a target, said transducer being electrically interconnected to said light sensor and producing either a buzzing sound or a vibrating sensation whenever said beam strikes the target presented by said light sensor, whereby the buzz or vibration alerts the golfer that the club is following a correct path and position through the course of a golf swing.
