Abstract: A golf calculator 10 provides a microcontroller-based circuit comprising a ROM 30 (read-only memory), a RAM 40 (random assess memory), a keypad 50, an LCD (liquid crystal display) or similar display 60 within an enclosure 70. The microcontroller 20 executes software permanently stored in the ROM which allows the determination of a number of statistics, including the handicap index, the handicap, a data element related to the golfer's consistency, the highest score, the lowest score, the average game and puts per game. Software routines also maintain a database of records, each record containing the game number, rank of the score of the game, date, score of the slope of the course, the course rating and the number of putts in a record associated with each game.
