Abstract

A method relating to an improved fitting system for a golf club shaft 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 infrared motion capturing cameras to record the location data of a golf club shaft throughout a swing. Based on the location data captured, one or more dynamic behavioral characteristics can be calculated to determine one or more preferred shaft characteristics. Using the preferred shaft characteristics, a shaft can be recommended for the golfer having this particular golf 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 (9)

1. An apparatus for testing a golf club shaft comprising:

a base;

a cantilever beam attached to said base via a hinge;

a clamp attached to a terminal end of said cantilever beam, said clamp adapted to secure a butt end of said golf club shaft;

an angle adjustment device capable of adjusting an angle of said cantilever beam relative to said base; and

a hook attached to a tip end of said shaft, wherein said angle adjustment devices alters said angle of said cantilever beam to allow for a weight to be attached to said hook at different angles.

2. The apparatus for testing a golf club shaft of claim 1 , wherein said hook is a balanced weight hook, said balanced weight hook applies an axial load to said shaft via said weight.

3. The apparatus for testing a golf club shaft of claim 1 , wherein said hook is a CG replicating hook, said CG replicating hook applies a load to said golf club shaft via said weight at a location offset from the axial axis of said shaft.

4. The apparatus for testing a golf club shaft of claim 1 , wherein said angle adjustment device is an actuator.
