Committees may permit the use of distance – measuring devices in tournament play. A Committee may establish a Local Rule allowing players to use devices that measure or gauge distance only. However, the use of a distance – measuring device that is designed to gauge or measure other conditions that might affect a player’s play (e.g., gradient, wind speed, temperature, etc) is not permitted regardless of whether such an additional function is used.
Rule 14 – 3 Artificial Devices, Unusual Equipment and the Unusual Use of Equipment is very specific in what is considered use of any equipment in an unusual manner. It states: “Except as provided in the Rules, during a stipulated round the player must not use any artificial device or unusual equipment in an unusual manner:
a.) That might assist him in making a stroke or in his play; or
b.) For the purpose of gauging or measuring distance or condition that might affect his play; or
c.) That might assist him in gripping the club, except that: (i) gloves may be worn provided they are plain gloves (ii) resin, powder and drying or moisturizing agents may be used and (iii) a towel or handkerchief may be wrapped around the grip.”
In the absence of a Local Rule, the use of distance – measuring device would be contrary to Rule 14 – 3.
