Check Out the USGA, R&A List of Non-Conforming Drivers. This is for all the hacks out there that are looking for a edge over your normal 4-somes. We all know the one guy that will do anything to get the edge to take 5 bucks off his buddies. On the other hand, keep a close watch over your shoulder as if your playing partners are anything like mine, they will pull this list from their bag and nail you and quite frankly I don’t blame them as in real terms it’s CHEATING.
According to Appendix II, section 5a of the Rules of Golf, “The material and construction of, or any treatment to, the face or the clubhead shall not have the effect at impact of a spring (test on file), or impart significantly more spin to the ball than a standard steel face, or have any other effect which would unduly influence the movement of the ball.”
If your driver is on that list, it means that the driver exceeds the limit of COR put in place by golf’s governing bodies. According to the USGA, the COR of a driver may not exceed a measurement of .830 (above that, they say, and the driver begins to act as a spring) in any competitions or in handicap rounds.
The R&A puts a limit on COR of .860, but will change to .830 on Jan. 1, 2008. In the meantime, the R&A has instituted a “condition of competition” that limits the COR in drivers played by highly skilled players to .830.
As of 2008, the .830 standard will apply across the board.
