Abstract: A system for monitoring play of a golfer (24, 26) comprises Location Information Transmitters (LIT) (52, 54, 56) at predetermined locations within a golf course and a Mobile Electronic Transmitter/Receiver (METAR) (48, 50) carried in association with a golfer (24, 26) on a golf bag (32) or a golf cart (28). Each LIT (52, 54, 56) periodically transmits a LIT code over a restricted transmission range (58, 60, 62) such that when the METAR (48) arrives within an LIT (54) transmission range (60), the METAR (48) receives the LIT code and subsequently initiates a counter to measure time required by the golfer (24) to move within transmission range (62) of a next LIT (56). If the counter exceeds a prescribed time, then a display on the METAR (48) indicates slow play. Additionally, the METAR (48) transmits the received LIT code and a METAR code to a Tracking Center (22) display terminal. Golf course personnel can monitor the display terminal and determine play of golfers (24, 26), golf cart (28, 34) utilization and golf hole (10, 14) utilization. When the golfer (24) causes a slow play indication, the Tracking Center (22) is notified and the slow golfer (24) is asked to increase the rate of play or leave the golf course. <IMAGE>
