A portable device measures the distances between a golfer and features located on a golf course based on global position data and predetermined location of features. The portable device includes a global positioning receiver to receive global position data and a wireless interface to communicate with a base device. The portable device couples to the base device to recharge and to record use. The base device may monitor the location of the portable device as the portable device traverses a golf course.
