Abstract

The invention relates to a portable distance tracking system for use by a player on a playing field. The system includes a mobile interface unit that has a memory element, position interface electronics, a data processor, and a player interface. The memory element stores digitized map representations of playing fields. The position interface electronics receivers position indicative signals that are representative of a geographical location of the mobile unit from an external source. The data processor couples to the memory element and to the position interface electronics and correlates the geographical location to a field location of the mobile interface unit on the playing field. The processor also determines the distance from the mobile interface unit to a first landmark. The player interface is coupled to the data processor and communicates the distance between the mobile interface unit and the first landmark to the player. According to a preferred embodiment, the playing field is a golf course and the first landmark is a flag location at a select hole on the golf course.
