The Rules of Golf allow a club or committee in charge of a competition to implement a local rule permitting the use of distance measuring devices (range finders and the like). If no such local rule is implemented, use of distance-measuring devices remains a breach of the Rules for which the penalty is disqualification.
In the event that a club or Committee in charge of a competition chooses to permit the use of distance-measuring devices, Golf Canada recommends the following wording for the local rule:
[Specify as appropriate, e.g., In this competition, or For all play at this course, etc.], 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.”
Golf Canada will not adopt the Local Rule allowing the use of distance-measuring devices at its championships or qualifying rounds.
