The United States Golf Association has compiled a list of driving clubs that do not conform and golf balls that do conform. These clubs are prohibited from use in any round of golf conducted under the USGA Rules. This includes competitions conducted by the American Junior Golf Association. They have also added a Conforming Driver Head list.
The AJGA will have an updated list on non-conforming drivers, conforming golf balls and conforming driver heads at the starting tee at all tournament rounds and at the registration table at all qualifiers and shotgun rounds. The AJGA also administers an equipment survey during the first round where each player must acknowledge what type of driver and golf ball they use to an AJGA official. It is recommended that all players check the status of their driver, golf ball and driver head prior to their round. The penalty for playing a shot with equipment not allowed by the USGA is disqualification.
