Abstract
A system measures and records deflection of an elongated shaft such as the shaft of a golf club and provides a trace or diagram of the swing of the club. The system includes an elongated rod, mounted to the golf club shaft, and a separate recording system. Preferably the recording system is a writing platform mounted to the golf club shaft. The recording member is biased into contact with the writing platform. During swing of the golf club, deflection of the golf club shaft causes relative movement between the writing implement and the writing platform and a trace or diagram of the golf club swing is created.
