GOLF CLUB SWING INDICATOR

摘要

A golf club swing-force indicator comprising an elongate housing adapted to be attached to the shaft of a golf club. A weight is movable on the housing between retracted and extended positions against spring action, becoming extended due to centrifugal force when the club 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.
