Please note that several driving club models appearing on the non-conforming list are also made in a USGA conforming version. Those versions that are non-conforming to USGA Rules are typically distributed and sold in locations outside of USGA jurisdiction. To help identify those models with conforming and non-conforming versions, there is a notation under the "Lofts" column indicating if there is a conforming version available. Additionally, the image will display both the conforming and non-conforming versions and indicate their differences.
