Abstract
A golf ball having a North pole and a South pole, an equator and a primary meridian, the equator and primary meridian divide the ball into North, South, East and West hemispheres, and Northeast, Northwest, Southeast and Southwest quadrants. A grid pattern projected on the ball surface divides the ball laterally and longitudinally into a number of overlapping zones. The dimples within the zones have average depths hex, hsx, hpx, hei, hsi and hpi and selected values of Δe, Δs and Δp which are the difference between the minimum and maximum values of the relative ratios of the dimple depths, hexr/heir, hsxr/hsir and hpxr/hpir determined when the ball is rotated by a value of θ from 0 to 360° about its polar axis.
