A golf club providing the golfer control over internal pressure therewithin to thereby most advantageously fine-tune the performance of the golfer\s golf club. The selectively pressurized golf club is composed of either a hollow head, a hollow shaft, or both hollow head and hollow shaft, either or both of which being selectively pressurized, separately or as one, either above or below atmospheric pressure. In the preferred embodiment, the gas pressure within the golf club is selectively accessed by the golfer via a valve mounted thereto, such as for example a pneumatic valve or an elastomeric valve. The head may have its own valve and its separate pressurizable internal chamber; the shaft may have its own valve and separate pressurizable internal chamber; or one valve may be present for selectively changing pressurization within fluidically communicating shaft and head internal chambers.

A golf club having selectively adjustable internal pressure, comprising: a head having a face and a neck, said head having a head chamber that provides an air tight hollow space within said head; a shaft connected with said neck, said shaft having a distal end opposite said neck, said shaft having a shaft chamber that provides an air tight hollow space within said shaft, said shaft chamber extending substantially between said neck and said distal end; plug means for providing an air tight seal between said head chamber and said shaft chamber so that said head chamber is fluidically isolated from said shaft chamber; first valve means for providing connection of a source of selectively pressurized gas to said shaft chamber to thereby provide a first gas having a first selected internal pressure in said shaft chamber; and second valve means for providing connection of a source of selectively pressurized gas to said head chamber to thereby provide a second gas having a second selected internal pressure in said head chamber.
