ABSTRACT:
In a golf ball having a spherical surface with numerous dimples thereon, the dimples have a diameter of 2 to 6 mm and number in all from 250 to 330, of which at least 60% are large dimples having a diameter of at least 4.5 mm. The volume of space in a dimple below a planar surface circumscribed by an edge of the dimple, summed for all the dimples on the surface of the ball, is from 320 to 360 mm3. The golf ball rises well when hit and is easy even for an inexperienced golfer to hit.
