  • Patent number: 5269528
    Abstract: A golf training device having a shaft with a lighting means located in each end of the shaft, with a light beam emitted from each lighting means away from the shaft, with each beam of light on a line with the other beam of light. A method of using the golf training device through a typical golf swing by locating a beam of light emitted from a lower end of the shaft on a line defined by an imaginary object ball and an imaginary target, with the light beam traveling along the line at appropriate points in the swing, and with the beam of light emitted from the opposite end of the shaft striking and traveling along the line at appropriate points in the swing. The device may also be used to achieve proper rotation of the hips and torso during the golf swing by using one's arms to hold the shaft against one's chest or lower torso while rotating one's body rearward and forward as in a typical golf club swing and observing the locations of the light beams emitted from the opposite ends of the shaft.
