## Abstract

A score tracking system may include a tracking module, companion device, and location system. The tracking module may be configured to be carried by a player competing in a golf tournament. The companion device may be configured to receive an input corresponding to a stroke event and that includes a time stamp corresponding to an occurrence of the stoke event. The location system may collect or receive location data, which comprises or is used by the location system to generate a plurality of sets of location coordinates. Each set of location coordinates may correspond to a location of the tracking module at a specified time. The location system may pair the time stamp with a set of the location coordinates corresponding to the location of the tracking module at the occurrence of the stroke event.
