Summary:A method of determining the frequencies of a golf club entails suspending the golf club in a substantial free state and thereafter striking or engaging the golf club to cause the same to vibrate or oscillate. Once the golf club has been excited, the method entails measuring the natural frequencies of the golf club. More particularly, in the substantial free state, the club is suspended by a flexible connector which is secured to the grip end of the club.
