ABSTRACT:
A balance-revealing apparatus for testing the balance of golf putters according to the present invention includes a base which is adapted to rest on a generally horizontal surface and an upwardly extending support column rigidly affixed to the base. Disposed in the upper end of the support column is a flanged bearing block and received by the bearing block is a pivot arm. The pivot arm is adjustably attached to a tubular holder which in turn receives the golf putter. The tubular holder is designed such that the putter retained by the holder is able to rotate about the longitudinal axis of the putter shaft such that upon free pendulum swinging of the pivot arm, the squareness of the putter face upon impact with the golf ball can be determined and represents a measure of the true balance or imbalance of the putter.
