ABSTRACT:
A golf club survey instrument includes a weight scale and a variably positionable fulcrum, enabling the instrument to be used determine the total weight of a golf club or the weight of each of its separate components, the swing weight of the club, and the center of gravity of the club. A linear scale also provides for the determination of the length of the club, or club components such as the shaft, grip, etc. The instrument comprises a base having a weight scale affixed at one end thereof, with the scale including a golf club grip retainer thereon positioned to place the end of the grip at the origin of the linear scale. The retainer also limits oscillations of the club, thereby providing for the rapid and accurate determination of the center of gravity of the club when balanced upon the fulcrum of the instrument. The base also includes a linear track therein and parallel to the linear scale, with the track providing for the adjustable positioning of the fulcrum therein. The device may include weight scales using either electronic load cells or strain gauges or mechanical operation, as desired. Thus, the present survey instrument provides for the rapid and accurate determination of a number of different golf club characteristics, thereby enabling a technician to make adjustments to the total weight and distributed weight of each club of a set as required to match a set of golf clubs accurately for weight, swing weight, and center of gravity.
