The present invention provides a golf ball having a plurality of dimples arranged on its outer surface, selected from two sets of dimples, the first set having a single radius cross section and the second set having a dual radius cross section. The dimples are arranged on the surface of the ball according to the rhombicosadodecahedron.

Golf ball with three dimple types

A two piece golf ball has a core compression in the range of 75 PGA to 89 PGA, a core diameter in the range of about 1.535 inches to 1.545 inches, a cover hardness in the range of 42 to 60 Shore D, and a dimple pattern based on the geometry of a icosahedron. An uninterrupted equatorial great circle path, corresponding to a mold parting line, is provided in the design for forming a cover of the golf ball in two parts. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

High performance two piece golf ball

A urethane-covered three-piece golf ball with a liquid-filled center, having a combination of center weight, thread windings, dimple configuration and compression that allows it to travel great distances, and to match the classic feel of 'Balata' balls, said combination at the same time complying with USGA regulations.

Polyurethane covered three-piece golf ball

A two piece golf ball has a core compression in the range of 77 PGA to 87 PGA, a core diameter in the range of about 1.532 inches to 1.548 inches, a cover hardness in the range of 66 to 72 Shore D, and a dimple pattern based on the geometry of a truncated octahedron. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

Two piece distance golf ball

The golf ball comprises all known cores provided with a cover produced by a polymer blend that combines the durability of a conventional cover with the feel of a traditional balata cover having a plurality of dimples in a modified dodecahedron pattern. The dodecahedron consists of twelve pentagons, which are subdivided into a total of sixty triangles. The triangles are then further subdivided into rows into which various diameter dimples are placed. The dimple pattern can be arranged to produce a pattern of ten great circles, which are free of dimples. The cover formulation is a blend of various ethylene/methacrylic acid copolymers wherein at least one copolymer has a high modulus and at least one copolymer has a moderate modulus forming a miscible blend having a PDI index that maximizes durability while still maintaining feel and playability.

Distance golf ball-DDH steel distance

A two piece golf ball has a core compression in the range of 67 PGA to 77 PGA, a core diameter in the range of about 1.535 inches to 1.545 inches, a cover hardness in the range of 65 to 71 Shore D, and a dimple pattern based on the geometry of a rhombicosadodecahedron. An uninterrupted equatorial great circle path, corresponding to a mold parting line, is provided in the design for forming a cover of the golf ball in two parts. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

Large core golf ball

A two piece golf ball has a core compression in the range of 77 PGA to 87 PGA, a core diameter in the range of about 1.535 inches to 1.545 inches, a cover hardness in the range of 53 to 59 Shore D, and a dimple pattern based on the geometry of a rhombicosadodecahedron. An uninterrupted equatorial great circle path, corresponding to a mold parting line, is provided in the design for forming a cover of the golf ball in two parts. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

Elastic core golf ball

A golf ball having between 1,000 and 2,500 dimples and a plurality of secondary depressions between said dimples on the exterior surface thereof. The secondary depressions are of spherical cross section and may be uniformly or randomly placed on the surface of the ball. The secondary depressions are of a depth from 0.001' to 0.005' and a diameter from 0.01' to 0.05'. The invention allows for decreased in-flight drag forces compared to a golf ball without the claimed secondary depressions.
