ABSTRACT:
A golf practice device comprising a golf club handle, and a shaft cut shorter than normal, with a unique head weighted to equal the swing of a regular club. The head contains a battery for a light, which is centrally mounted with lens and iris to produce a focused, rectangular spot of light, parallel to the shaft center line. The device also has a combination level-and-centrifugal switch that turns on the light spot when the shaft is level at the start of the down swing, and also as the head travels through the bottom of the swing. The rectangular light beam shows the path of the swing through a target ball, allowing the user to check the accuracy of the swing as well as the squareness of the club head to a target line. The target comprises a golf ball with two electronic receivers on either side in a straight line. The visual light path shows the direction of the swing, and the sound from the electronic receiver indicates to the golfer when a precise swing has been achieved. As repeat accuracy improves with practice, the light beam can be narrowed by adjusting the iris for still greater accuracy.
