Abstract
The present invention provides a golf ball having an aerodynamic subsurface for packing dimples. More particularly, the invention relates to a golf ball having an exterior surface and at least a first subsurface containing at least two dimples located solely on the subsurface and lying below the exterior surface of the golf ball. A transition zone between the exterior surface and the subsurface is disclosed having an angle of transition and a top radius and a bottom radius. According to the present invention, the exterior surface and at least the first subsurface have at least a first and second surface colors that are different.
Claims14
A golf ball comprising:
- a core;
- a cover surrounding the core;
- an exterior surface provided on the cover having an exterior radius R0;
- at least a first subsurface having a first perimeter and a subsurface radius R1 and at least two subsurface dimples located solely within the first subsurface;
- and
- wherein the first subsurface is offset from the exterior surface by a value δ1 such that R1=R0−δ1 and δ1 is between about 0.003 and about 0.020
- wherein the exterior surface has a first surface color and the first subsurface has a second surface color different than the first surface color.
