The GCWGA will allow the use of approved Electronic Measuring Devices (EMDs) in all GCWGA tournaments and team play beginning in 2008. 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 her 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.
Additionally, the distance between any objects is considered to be a matter of public information and therefore not advice. Such information may be shared without restriction. Players may also share EMDs and may share any measured yardage with another player. (see USGA Rules Decisions 5-1/5 and 8-1/2).
Players who have an EMD are not required to share information with their opponents but, in the name of friendly competition and sportsmanship, the GCWGA would always encourage you to do so. After all, one of the stated purposes of the GCWGA in our by-laws is to “maintain high standards of sportsmanship”.
