Abstract: The system uses a microcomputer (81) to provide a practical and useable graphic representation of the fairways (12) and greens (11) for any golf course in order to record shot locations (14) and measure playing performance during an actual round of golf as contrasted to a simulation of a golf game. A player will interact with the diagrams produced by the system's software and illustrated on a display or monitor (80). The design of the system enables the player to accurately determine the locations of all shots and calculates and displays:(a) shot or club distances (FIG. 6 );(b) shot or club accuracy (within 1-2 yards) to the center of the green from ball locations (14) ranging up to 200 yards from the center of the green;(c) shot or club accuracy (within 1-2 feet) to the pin (cup location) from ball locations (14) ranging up to 200 yards from the center of the green even though the pin location may be different each time the course is played;(d) statistical data, i.e.
