ABSTRACT:
A golf ball sphericity gauge comprising complemental shells defining an interior ball cage having interiorly directed measuring seats lying within the surface defined by a sphere of predetermined sphericity. The shells are separable to permit insertion of a golf ball into the ball cage, and the ball cage includes an aperture enabling manual rotation of a golf ball within the ball cage thereby to detect differences between the sphericity of the golf ball and the predetermined sphericity.
