Abstract

A golf ball of improved playing characteristics weighing no more than 1.62 ounces and having a mean outside diameter of 1.70 to 1.80 inches. A dimple pattern on the surface of the ball may include a plurality of dimples which have different diameters. The spin rate of the ball can be increased by providing a cover having a Shore D hardness of 50 to 63 with the ball having a coefficient of restitution of 0.77 to 0.85.

Claims

a ball having a core and cover, a mean outside diameter from 1.70 to 1.80 inches, and a weight no greater than 1.62 ounces;

said cover having a Shore D hardness of 63 or lower; and

said ball having a coefficient of restitution of at least 0.77.

2. The golf ball of claim 1 wherein said Shore D hardness is from 50 to 63.

3. The golf ball of claim 1 wherein said coefficient of restitution is from 0.77 to 0.85.

4. The golf ball of claim 1 wherein the mean outside diameter of said ball is substantially 1.72 inches.

5. A golf ball of improved playing characteristics comprising

a ball having a core and a cover, a mean outside diameter from 1.70 to 1.80 inches and a weight no greater than 1.62 ounces;
