PROBLEM TO BE SOLVED: To easily inform every player of the display content of a display at a cart by a method wherein information on a master device which can process information from a GPS is displayed after it is transmitted to a slave device capable of being carried by every player. SOLUTION: A GPS device 20, at a cart, which receives a GPS signal 45 from a satellite corrects a position by a correction signal 46 from a control center and the precise position of the cart is positioned. The GPS device 20 at the cart sends an own-vehicle-position signal 47 to the control center, and it sends a signal 48 about the distance up to a putting green of every player to a slave device 28 which is carried by every player. Since the slave device 28 displays the distance, every player can know the distance up to the putting green easily when he sees the display at the slave device 28 which is carried, without going to see the display at the GPS device 20 at the cart. In addition, the own-vehicle-position signal 47 of the cart is sent to the control center, and it is possible to know a distance up to a cart used by a preceding group. |
