Golf ball with dimple patterns having depth progression

A golf ball having a spherical surface, comprising

• (a) a pattern defined on the golf ball surface, said pattern including a plurality of geometries, said geometries comprising triangles each having a perimeter defined by great circles on the golf ball surface, one of said great circles defining an equator which divides the golf ball surface into two hemispheres;
• and
• (b) a plurality of dimples arranged within said triangles, respectively, with said great circles and said triangles being free of dimples, said dimples comprising at least two groups of dimples, a first group of dimples having a first depth and being arranged exclusively in contiguous relation and adjacent to at least a portion of the perimeter of said triangles and a second group of dimples having a second depth different from said first depth and being arranged within said first group of dimples, said first and second depths being independent of a width of dimples of said first and second groups of dimples, respectively, and providing a dimple depth progression within each triangle either from a center portion of each triangle outward or from a perimeter portion of each triangle inward, whereby the golf ball has improved aerodynamic properties.
