Rule 14-3 governs the use of equipment and devices (including electronic devices) that might assist a player in making a specific stroke or generally in his play.
Golf is a challenging game in which success should depend on the judgement, skills and abilities of the player. This principle guides the USGA in determining whether the use of any item is in breach of Rule 14-3.
For detailed specifications and interpretations on the conformity of equipment and devices under Rule 14-3 and the process for consultation and submission regarding equipment and devices, see Appendix IV.
Except as provided in the Rules, during a stipulated round the player must not use any artificial device or unusual equipment, or use any equipment in an abnormal 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 conditions that might affect his play; or
c.
That might assist him in gripping the club, except that:
(i)
gloves may be worn provided that 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.
1. A player is not in breach of this Rule if (a) the equipment or device is designed for or has the effect of alleviating a medical condition, (b) the player has a legitimate medical reason to use the equipment or device, and (c) the Committee is satisfied that its use does not give the player any undue advantage over other players.
2. A player is not in breach of this Rule if he uses equipment in a traditionally accepted manner.
Match play - Loss of hole; Stroke play - Two strokes.
For subsequent offense - Disqualification.
In the event of a breach between the play of two holes, the penalty applies to the next hole.
Note: The Committee may make a Local Rule allowing players to use a distance-measuring device.
If a player's club strikes the ball more than once in the course of a stroke, the player must count the stroke and add a penalty stroke, making two strokes in all.
A player must not make a stroke at his ball while it is moving.
When the ball begins to move only after the player has begun the stroke or the backward movement of his club for the stroke, he incurs no penalty under this Rule for playing a moving ball, but he is not exempt from any penalty under Rule 18-2 (Ball at rest moved by player).
(Ball purposely deflected or stopped by player, partner or caddie - see Rule 1-2)
When a ball is moving in water in a water hazard, the player may, without penalty, make a stroke, but he must not delay making his stroke in order to allow the wind or current to improve the position of the ball. A ball moving in water in a water hazard may be lifted if the player elects to invoke Rule 26.
