The use of electronic Distance Measuring Devices (DMDs) remains contrary to the Rules of Golf although clubs and organising committees may permit their use by Local Rule and in the conditions of competition (see the Note to Rule 14-3 and Appendix 1, Part B, Paragraph 9 in the Rules of Golf). Devices which measure functions in addition to distance (eg. altitude, temperature) are not permitted in any circumstances even if these functions are switched off. The penalty for using such a device on the golf course in a competition is disqualification.

The R&A and USGA have recently confirmed that DMDs will not be allowed in any of their events in 2010.

The SLGA, in common with the Ladies’ Golf Union and the other National Governing Bodies except the English Golf Union, will not be permitting DMDs in any of its Championships and other competitions in 2010. This includes the SLGA Medal Regional Finals, the semi-finals and final of the Scottish Match Play Foursomes, the County Finals, County Open Meeting, the Champion of Champions and the Commonwealth Spoons.  

Players should note that electronic DMD’s may be used at club level in SLGA Medals and in the rounds up to and including the quarter finals of the SLGA Scottish Match Play Foursomes only if the relevant Local Rule has been adopted for the course in question by the club committee.
