A regulation golf ball, comprising: (a) a low density center having a maximum diameter of 1.25 inches; (b) a molded encapsulating mass surrounding said center, wherein the material in contact with said center is further characterized as a highly resilient synthetic elastomer composition having a minimum Shore A Durometer hardness of 70, and a minimum specific gravity of 1.00: (c) and a patterned surface contouring of predetermined structure contained within the outer surface of said golf ball; (d) said center having a compressibility of less than 10 percent of the compressibility of the material in contact therewith, and a density less than the maximum prevailing density of said encapsulating mass, for the purpose of effectuating an increase in ball moment of inertial. |
