Abstract

A golf ball weighing no more than 1.62 ounces and having a mean outside diameter of at least 1.70 inches. The core compression of the ball and the cover hardness are selected so as to provide a finished ball having a P.G.A. compression of 70 or less and a coefficient of restitution from 0.780 to 0.825.

Claims

1. A golf ball of improved playing characteristics comprising

a ball having a core and a cover and a mean outside diameter of at least 1.70 inches;

said ball weighing no more than substantially 1.62 ounces;

a dimple pattern comprising a plurality of dimples on the surface of said ball, said dimple pattern covering at least 70.0% of the surface of said ball;

said golf ball having a P.G.A. compression of 70 or less.

2. The golf ball of claim 1 wherein said ball has a P.G.A. compression of 69 or less.

3. The golf ball of claim 2 wherein the coefficient of restitution is from 0.780 to 0.825.

4. The golf ball of claim 2 wherein the coefficient of restitution is substantially 0.80.

5. The golf ball of claim 1 wherein said core has a P.G.A. compression of 48 or less, said cover has a Shore D hardness of 60 to 65, and said ball has a P.G.A. compression of 60 to 70.

6. The golf ball of claim 5 wherein the coefficient of restitution is from 0.780 to 0.825.

7. The golf ball of claim 5 wherein the coefficient of restitution is substantially 0.80.

8. The golf ball of claim 1 wherein said core has a P.G.A. compression of substantially 43, said cover has a Shore D hardness of substantially 64, and said ball has a P.G.A. compression of 60 to 70.

9. The golf ball of claim 1 wherein the coefficient of restitution is from 0.780 to 0.825.

10. The golf ball of claim 1 wherein the coefficient of restitution is substantially 0.80.
