ABSTRACT:
An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.
