The present invention automatically calculates a score so that a golf player can concentrate on his or her play. When the golf player plays a game, while wearing the golf navigation terminal of the present invention on the waist, the golf navigation terminal automatically detects how the player is doing and sends this to the golf navigation device, and the golf navigation device then calculates the player's score. Afterwards, the score is wirelessly communicated to the golf navigation terminal. The score is fixed after the player's confirmation or correction. According to the present invention, the player may view his or her score from time to time, either through a display on the golf navigation terminal or on the golf navigation device.
