Abstract

A method relating to an improved swing characteristic capturing system that can be used for a golf club shaft fitting system is disclosed herein.

Even more specifically, the present invention relates to the utilization of cameras to record the location data of a plurality of markers located on a golf club shaft throughout a swing. The current inventive fitting methodology is preferred to the archaic fitting method of using data gathered from the result orientated ball flight data together with a tedious process of having to try numerous different shafts.
