ABSTRACT:
A golf club, such as a conventional metal/wood driver, including a hollow club head, an elongated shaft, and a hollow hosel joined at one end thereof to the club head and connected at the opposite end to the shaft. A normally closed air valve is located inside the hollow hosel. Prior to connecting the shaft to the hosel, the normally closed air valve in the hosel is momentarily opened so that a supply of fluid (e.g. air) under pressure can be delivered to the interior of the club head through the hosel. By virtue of the foregoing, the hollow club head will be filled with air so as to become less susceptible to compression during its impact with a golf ball, whereby a harder striking force will be imparted to the golf ball to enable the golfer to drive the ball a longer distance. A pressure gauge and a pressure relief valve are carried by the hollow club head to provide the golfer with a visual indication of the fluid pressure at the interior of the head and avoid over-pressurized conditions therewithin.
