The golf ball has a core and a cover. The cover has dimples ranging in number from 100 to 1,000 and having a total volume of less than 1.5% of the ball volume on its exterior surface. The dimples have diameters between 0.04 and 0.3 inch and depths between 2/1,000 and 20/1,000 of an inch. The golf ball weight ranges from 1.35 ounces (38.3 grams) 1.55 ounces (43.97 grams).
