ABSTRACT:
A golf distance indicator system provides a measurement of the distance between a golfer and the green which he is approaching. The system comprises a base unit mounted at or near the pin on the green and a remote unit carried by the golfer. Upon command, the remote unit transmits a radio pulse to the base unit. The base unit immediately returns an acoustic or sonic signal, preferably an ultrasonic signal, in response to the received radio pulse. The remote unit includes internal logic for determining the distance from the base unit to the remote unit from the time interval between the transmission of the radio pulse and the reception of the ultrasonic signal based upon the speed of sound waves through air. The remote unit also receives input wind conditions and determines range and direction corrections to the actual distance based upon these wind conditions. From the wind corrected distance, the remote unit automatically selects the proper club for the next shot.
