ABSTRACT:
A golf ball with improved flight distance is disclosed. The golf ball has at least three pluralities of dimples in its spherical surface. The dimples of each plurality share the same diameter and depth characteristics, such characteristics varying from the corresponding diameter and depth characteristics of the dimples of the other pluralities of dimples. However, the ratio of the diameter to depth of the dimples of a particular plurality of dimples approximates the ratio of the dimples in every other plurality of dimples such that the difference between the ratio of the dimple of one plurality of dimples and any other plurality of dimples is less than 0.3.
