The Prodigy M4 is one of the most widely used and loved midrange discs in our line up. The new M4 Mini is based off the same design at approximately 70 percent of the size, weighing in at 67 grams, with a diameter of 15 ¼ cm (6 in). The M4 Mini is tons of fun to throw and flies great. Its smaller diameter and lighter weight make it a great option for young children, but it also brings a different dynamic to the course for adult throwers, as well. It can also be used as a legal marker during competitive play.
