Designed with the newer player in mind, the Underworld will allow any player to accomplish an anhyzer shot. It is understable and low profile. Great for players to buy as their first disc, the Underworld will be just what a beginner needs. For professional players, it makes a great continuous anhyzer line and is great for rolling right out of the box.
