List of Conforming Driving Clubs
The R&A periodically issues a List of Conforming Driver Heads that lists driving clubheads that have been evaluated and found to conform to the Rules of Golf. The Note to Rule 4-1 states:
“The Committee may require, in the conditions of a competition (Rule 33-1), that any driver the player carries must have a clubhead, identified by model and loft, that is named on the current List of Conforming Driver Heads issued by the R&A”.
If the Committee wishes to limit players to drivers that have a clubhead, identified by model and loft that is on the List, the List should be made available. This List can be found on The R&A’s website.
This condition of competition is normally introduced for competitions involving expert players at elite level and it is not recommended that such a condition be introduced in Club level golf. Where the List is not operational, the player’s clubs must conform with Rule 4-1 and the provisions, specifications and interpretations set forth in Appendix II of the Rules of Golf.
The suggested wording for such a condition of competition is contained in Appendix I, Part C, of the Rules of Golf.
