Abstract: A plurality of distinctly different 18 hole golf tournament maps are stored in rolled condition on separate rollers in a carrying case. A golf ball driving unit simulates how far a driven golf ball will travel. The golf ball driving unit comprises a housing having an upright shaft rotatably mounted therein. An arm extends perpendicularly from the shaft and is freely rotatable with the shaft in a plane perpendicular to the shaft. A golf ball is affixed to the free end of the arm. A counter in the housing is coupled to the shaft for counting the revolutions of the shaft and indicating the number of revolutions on a distance scale thereby indicating to a user driving the golf ball wtih a golf club how far the driven ball travels to a selected hole on a selected one of the maps. A marking device indicates the distance of a drive on a selected map.
