Abstract: A sports ball resiliency testing device is disclosed. The device includes a housing that defines a receiving area into which a ball is placed. The receiving area is configured and dimensioned to act upon the contours of the ball. A movable member extends into the receiving area and makes contact with the surface of the ball. The movable member is urged by a spring so as to exert a compressing force on the ball. The urging force of the spring is adjustable so as to provide for various testing ranges. The ball thus exerts a resisting force against the movable member. A value of the resisting force is determined when an equilibrium is reached between the compressing force and the resisting force. This value indicates the playability of the ball.
