Abstract: A golf putter head incorporating a resonating cavity which provides acoustic indicia of optimum contact between the putter head and a golf ball. A putter head in accordance with the present invention comprises a main weighted body and a striking member secured thereto. The main weighted body has a striking face which is intended to be substantially perpendicular to the putting surface. A cavity of predetermined geometry is centrally disposed into a recessed portion of the striking face of the weighted body. A striking plate is adapted to be frictionally engaged within the face recess. A cavity which is a mirror image of that disposed in the main weighted body is disposed in the striking plate. When the striking plate is frictionally inserted within the recess in the face of the weighted body, the cavities disposed in the respective members are placed in abutment to one another thereby creating a unitary, resonating cavity fully bounded by the surfaces of the adjacent main weighted body and the striking plate.
