Abstract
A measurement apparatus primarily for use during the purchase of golf clubs for indicating angle modifications between head and shaft needed to assure zero angle between the sole and the underlying surface for a particular golfer. The apparatus comprises a club simulation member having a shaft and grip of a conventional golf club but terminating at its non-grip end in a yoke member. The yoke member is attached to a hinge bracket which is, in turn, attached to a pointer positioned at a predetermined angle relative to the axis of the shaft. The pointer is positioned within a housing preferably covered by a face of which at least a portion is transparent to permit observation of the angular position of the pointer when the golfer grasps the club simulation member in a ball addressing configuration. The face may also advantageously provide indicia to permit convenient observation of the angle of the pointer which may easily be calibrated to correspond to the angle between the shaft and the underlying surface.
