Abstract

A golf ball having three or more sets of dimples with each set having substantially the same dimple diameter and each dimple of each set having the same dimple edge angle. Each set of dimples has diameters which differ substantially from each other set. Golf balls having 50% to 80% or more of their surfaces covered with dimples are within the present invention.

Claims

1. A golf ball having three or more sets of dimples on its surface with all dimples within a set having substantially the same diameter and each set diameter differing substantially from each other set diameter and in which each set has substantially the same dimple edge angle.

2. A golf ball of claim 1 having dimples over 50% or more of its surface.

3. A golf ball of claim 2 in which the edge angles of the sets are all within two degrees of each other and all such edge angles are in the range of 14-26 degrees.

4. A golf ball of claim 1 having dimples over about 70% to about 80% of the ball surface.

5. A golf ball of claim 4 in which the edge angles of the dimples are all within two degrees of each other and all such edge angles are in the range of 14 to 22 degrees.
