ABSTRACT:
A device is disclosed for testing the resilience of a game ball. The device comprises a tubular member having an opening at one end for receiving a game gall to be tested. A striking surface on the other end of the tubular member and calibrated markings along the length of the tubular member indicate the degree of resiliency of the game ball by virtue of the distance the game ball rebounds from the striking surface when the ball is dropped from the opening.
