ABSTRACT:
A swing-force indicator for a playing piece of sports equipment, such as a golf club, racket, baseball bat or the like, comprising an elongate housing adapted to be attached to a portion of the piece. A weight is movable on the housing between retracted and extended positions against spring action, becoming extended due to centrifugal force when the piece is swung, and being held in any extended position by a releasable catch. Normally the weight is held retracted by a yieldable biasing means which acts counter to the centrifugal force. An indicator shows the degree of extension of the weight, and gives a reading that is proportional to the force of the swing.
