Abstract
A meter which detects, determines and displays the highest speed obtained in a golf club swing, being coin-operated, highly portable and battery powered. The meter includes a stabilizing base platform supporting a vertical post holding an electronic control box having a LCD, indicator lights and coin receiver. The base sits on a ground surface unattached, and supports a rubber golf tee secured relative to a pair of light sensors and light emitters. The sensors are mounted on the pedestal, and register an interruption in light directed into the sensors from the lights. The lights are mounted on the base and secured in the proper alignment with the sensors so that the entire unit can be easily moved such as for mowing around without misalignment occurring. The light sensors and the lights are on oppositely disposed sides of the tee so that a swinging golf club will interrupt the lights and cause the sensors to signal counters to begin or stop counting. Two sensors are used in spaced relationship to one another, one sensor straight across from each of the two fixed lights. The sensors are contained within collimator tubes which are aimed downward at an angle toward the lower positione…
