Abstract
A combination dimple pattern on the surface of a golf ball is characterized by both non-circular and non-circular compound dimples. The compound dimples include a first non-circular dimple portion and a second non-circular dimple portion arranged in a bottom surface of the first portion, with the second dimple portion having a depth greater than the depth of the first circular portion. The combination of compound and circular dimples on the surface of the ball improves the aerodynamic efficiency of the ball for more control of lift and drag of a spinning golf ball during flight.
