1. A golf swing evaluation system comprising:
- a golf club including a shaft having a club head with a golf ball striking face attached at one end and a grip portion attached to an opposite end;
a plurality of sensing means embedded within said club head and oriented for sensing an impact of said striking face on a golf ball and for generating associated sensor signals representing characteristics of said impact including at least a force of said impact and a location of said impact on said striking face;
a force circuit electrically connected to said sensing means and being responsive to said sensor signals for generating an indication signal representing said characteristics of said impact; and
means responsive to said indication signal for generating a visual indication of said characteristics of said impact, said visual indication including a peak magnitude force indication and a graphic indication of the location of said impact on said striking face.

Abstract
A golf swing evaluation system includes a golf club containing a sensor and an associated display for indicating the force and location of the impact of the club head against a golf ball. The sensor generates a sensor signal to a force circuit which generates an indication signal having characteristics of the impact. The indication signal is sent to a graphic display and/or a computer for evaluation. The sensor can also be an accelerometer for generating the acceleration characteristics of the club head throughout the swing. Several sensors can be utilized to provide information as to the location of the impact. The display can be located in the club grip or worn by the golfer.
