ABSTRACT:
A fitting golf club for determining the flexibility of a golf club shaft, the club including an elongated shaft having one shaft end portion adapted to be grasped in a person's hands and an opposite shaft end portion with a golf club head attached. An indicia bearing screw head is adjustable between a plurality of different positions. Mechanisms associated with the adjustable head are operative responsive to the centrifugal force applied upon swinging of the fitting golf club. The mechanisms include a weight pivotally mounted within the head on an axis perpendicular to the shaft and parallel with the swing direction, the weight being movable between an armed position adjacent the upper side of said head to a released position adjacent the lower side of said head. The optimum shaft flexibility for the person being tested is determined by the position of adjustment of the adjustable head when compared with the time of release of the weight.
