ABSTRACT:
A scale is provided for establishing a swing inertia value of golf clubs by providing support means arranged to contact the grip portion of the club such that the axis of rotation of a person's grip on the grip portion of the club when in the act of swinging the club is disposed vertically above the pivotal axis of a balance beam of the scale. The scale supports a golf club for determining such swing inertia value and includes calibrations which comprise values determined by multiplying the head weight of the club by the length of the club shaft extending from the pivotal axis of the balance beam to the center of gravity of the club head. The scale can also be used to determine the head weight of a club.
