Callaway Driver Fails USGA Test

Callaway Golf's latest product, the ERC driver, has reportedly failed the United States Golf Association's 'coefficient of restitution' test for spring-like effect.

Callaway spokesman Larry Dorman dismissed the USGA's findings as of "no concern to us" as the company does not plan to retail the new club in the United States.

Dorman added: "The USGA kept asking for it, they called on numerous occasions as a result of the publicity it received and they told us they were going to test it anyway."

The ERC is already on sale in Japan and is expected to be available in Europe shortly.
