First Claim
1. A golf ball having a spherical surface with a plurality of sets of dimples formed therein, the dimples of each set having a circular periphery of a different diameter and having a different depth than the dimples of other sets, the depth of the dimples increasing as the diameter of the dimples decreases, the side surface of each dimple being formed by a truncated cone.

Abstract
A golf ball is provided with five sets of dimples, the dimples of each set having a different diameter and a different depth. As the diameter of the dimples decreases, the depth of the dimples increases, and the aspect ratio of the depth to diameter for each set is within the range of 0.025 to 0.055 inch. The side surface of each dimple is formed by a frustum of a cone.
