The golf ball has small depressions on it called dimples. Typically, a Golf ball has between 300 and 500 dimples to its surface, which varies by manufacturer and design. Dimples help the ball to fly further with less air resistance and more accurately, making it more aerodynamic. Some variation in the flight, spin and control properties may occur with varying dimple patterns. Designs are thoroughly tested by manufacturers to ensure a balance of distance, stability and performance in varying playing conditions and throughout different golfer preferences.
