Abstract: A golf club having a retractor system disposed in the club head. The retractor system may be pneumatic, which allows pressure from an expanding gas to alternatingly operate on opposite sides of a seal ring attached to a piston. The golf club includes a hollow shaft extending from one end and terminating in a club head. The club head includes a piston cylinder extending from a gas injection port terminating proximate to a front face of the club head. A feed chamber is disposed on each side of the piston cylinder, each of which is in fluid communication therewith. A piston is disposed within the cylinder and includes a ring seal at one end. The ring seal forms a fluid tight seal with the walls of the piston cylinder. A receptacle, adapted to provide a rapidly expanding gas, is disposed proximate to the injection port to direct expanding gas therethrough, moving the piston away from the injection port.

Abstract: A ballistic impeller golf club includes a piston and a explosive charge disposed within the head of the golf club. The piston is adapted to travel outwardly from the club head in response to a rapidly expanding gas produced by the explosive charge. A golf-ball, disposed proximate to the club, is struck by the piston, thereby causing the golf-ball to travel a predetermined distance. A range control system is disposed within the club head which allows varying the force that will be imparted on a golf-ball by the piston.
