In accordance with the present invention, a golf ball (10, 110, 200, 300) includes an outer surface (12, 112) and a plurality of dimples (14, 16a-d, 214, 314, 315) formed thereon. At least one of the dimples is a concentric ring dimple (14, 114, 214, 314, 315). Each concentric ring dimple (14, 114, 214, 314, 315) includes a central depression (18, 118), and at least one annular depression (20, 120, 124) that concentrically surrounds the central depression (18, 118). A land ring (22, 122, 126) extends between the central depression (18, 118) and the annular depression (22, 122, 126). When the concentric ring dimple (14, 214, 315) includes additional annular depressions (120, 124), land rings (122, 126) extend between the adjacent annular depresssions. |
