Callaway Golf Club Drivers - What is Characteristic Time?

Characteristic Time (CT) is a measure of impact efficiency, or the �spring-like effect� in a driver. CT is therefore a measure of the responses of a golf club driver face to an object impacting it. The higher the CT impact efficiency, the more efficient the energy transfer is from the clubface to the ball which means potentially the ball will go a longer distance.

Callaway Golf Club Drivers - How Does CT Testing Work?

CT golf club driver testing is conducted by the Royal and Ancient Golf Club of St. Andrews in the UK and by the United States Golf Association. The testing consists of a steel weight suspended from a pendulum, which is then released from varying heights to strike the clubface. The amount of time that the weight and clubface are in contact determines a driver's CT. The limit has been set at 239 microseconds, plus a test tolerance of 18 microseconds, for a maximum of 257 microseconds. This testing was jointly developed and approved by the R&A and the USGA.
