The List of Conforming Driver Heads identifies the models and lofts of all driver heads that have been submitted for evaluation to The United States Golf Association and/or R&A and have been determined to conform to the Rules of Golf. It is updated by 08:00 (EST) every Monday for USGA jurisdictions and 00:01 (GMT) for R&A jurisdictions.
Driver heads are listed in alphabetical order by manufacturer or by product name, depending on which PDF list you have printed. Each model is listed as a separate entry with corresponding lofts and identification markings that are essential to determining whether the driver listed is the same as the driver in question. There are sometimes only subtle differences in the markings differentiating two different models of a driver head. For example, one model may have a degree symbol (conforming) and a similar model could be without a degree symbol (USGA non-conforming or R&A non-conforming in 2008), and those differences vary from manufacturer to manufacturer. As a result, if all markings of the clubhead do not match exactly to a club that is in question, it may be a different model and you should check the Non-Conforming Driver List (R&A Non-Conforming 2008) to determine whether it appears on that List. If you have any question regarding the conformance status of any club, please contact the USGA or R&A for further assistance.
A link to an image of each driver included on this list is available through the searchable online database by clicking the 'View Photo' link. Please note that only the image of the driver head's sole is provided. Therefore, it should only be used for reference purposes. There are often models that have identical sole markings but have different face, crown, toe and/or heel markings. The sole markings alone are not enough to conclude that the clubhead in question is the model listed.
