In a historical context, the game has seen progressive developments in the clubs and balls available to golfers who, through almost six centuries, have sought to improve their playing performance and enjoyment. 

While generally welcoming this progress, the USGA remains vigilant when considering equipment Rules. The purpose of the Rules is to protect golf's best traditions, to prevent an over-reliance on technological advances rather than skill and to ensure that skill is the dominant element of success throughout the game.

The Equipment Standards staff is located in the Research and Test Center at Golf House. This high-level technology facility houses both the specialized golf club and ball testing equipment and the highly educated and skilled individuals whose work is focused on understanding the game's technology and the potential effect of new equipment upon the game. During 2007, there were several noteworthy actions regarding equipment Rules:

. The spin research project was completed during the year.  This research was undertaken to better understand the factors involved in the creation of spin when a shot is made. This work has been focused on iron spin - particularly on shots from the rough.  During 2007, additional research reports were published by the USGA and the project was completed, resulting in proposed changes to the Rules of Golf governing groove dimensions.  Per the USGA Notice and Comment process, manufacturers and other interested parties provided the USGA with their comments about the proposed Rule change.  These comments are in the process of being evaluated.  

. The ball research project continues at the USGA Research and Test Center. This study, which was begun in 2002, is a wide-ranging investigation into golf ball design, construction, materials and performance. During 2007, the USGA conducted player testing with reduced-distance prototype balls.  This testing was conducted with both amateur golfers and Tour professionals and was focused on how reduced distance balls could affect the playing of the game.  Testing is ongoing.  While there are no current plans to make any changes to the Rules regulating golf balls, it is important that the USGA be prepared in case that becomes necessary.

. A revision to the Rules governing club adjustability was approved for implementation in 2008.  Under the new Rules, additional forms of club adjustability will be permitted.  This change should help many golfers obtain clubs that are better suited to their needs.
