ABSTRACT:
A method for measuring the swing time of a golfer's swing and selecting a golf club having the inverse of four times its natural frequency which is approximately equal to the swing time. The golfer's swing time is defined as the time elapsed between maximum acceleration of a club head during downswing until ball impact. In the preferred embodiment, an accelerometer is mounted within the club head and is connected to an electronic data processor. A graph of club head acceleration versus time is plotted and the swing time is measured from the graph, between peak acceleration and ball impact.
