Patent ID: 7083533

Claim:
A golf ball comprising an elastic solid core, a resin cover which encloses the core and has a plurality of surface dimples, and a mantle layer situated between the core and the cover; wherein the cover and the mantle layer have a difference in Shore D hardness therebetween of at most 10, and the dimples have a total volume of 280 to 350 mm 3 , wherein the ball, when hit, has a coefficient of lift CL and a coefficient of drag CD such that the ratio CL/CD is 0.676 to 0.796 at a Reynolds number of 200,000 and a spin rate of 2,700 rpm, 0.813 to 0.933 at a Reynolds number of 120,000 and a spin rate of 2,400 rpm. and 0.856 to 0.976 at a Reynolds number of 80,000 and a spin rate of 2,000 rpm.
