The following local rule is applicable to all EDGA sponsored events:

Distance-Measuring Devices

A player may obtain distance information by using a device that measures distance only. However, if, during a stipulated round, a player uses a distance-measuring device that is designed to gauge or measure other conditions that might affect his play (e.g., gradient, wind-speed, temperature, etc.), the player is in breach of Rule 14-3, for which the penalty is disqualification, regardless of whether any such additional functions are actually used.”
