Claim:
1. A double action golf putter head comprising: (a) a putter head having a front impact surface and a rear surface; (b) a centrally located bore within said putter head having a threaded orifice within said putter head rear surface; (c) one or more springs, and a spring loaded central weight comprising a moveable cylinder weight located within said central bore; (d) one or more set screws to secure said one or more springs, and said cylinder weight located within said central bore, further wherein the position of said spring loaded central weight is adjustable by adjustment of said set screws thereby modifying the forces on said spring loaded central weight, and resulting in the ability to adjust the forces on the golf ball at the time of impact with the putter; and (e) further wherein said putter head includes two club head side extensions located laterally to the left and right of said centrally located bore, for the purpose of housing balance adjustment weights; wherein upon impact of said putter head front impact surface with a golf ball, said cylinder weight moves toward said front impact surface compressing said one or more springs, thereby creating a double action momentum swing and a secondary striking action to accelerate and increase the forces against the golf ball.
