What is meant by frequency matched shafts?
Frequency matching is done with an electronic device called a frequency analyzer. A frequency analyzer gives a digital readout of the stiffness of a shaft. The flexibility of the shaft is measured by clamping the butt end of the shaft and then pulling the clubhead towards you and releasing it so the club oscillates freely at its natural frequency. The number of times the shaft oscillates is measured electronically and calibrated as cycles per minute (CPM). A stiff shaft would oscillate faster and produce a higher CPM reading than a more limber shaft. With selective tip trimming, your shafts are perfectly matched in flex guaranteeing all your clubs feel and swing the same be it irons or woods. Because your shafts all have the same predetermined flex, you can groove your swing to that one flex that best matches your swing tempo and swing speed. The net result is more consistent shotmaking. In addition, with a frequency analyzer it is possible to duplicate the shaft flex of your favorite
