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. More specifically, the present invention utilizes specific data gathered from the golfer'"'"'s golf swing itself to determine the best performing golf club shaft for this particular golf swing. 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.

Claims
