This starter set features the “US” series discs by Prodigy Ace Line. The “US” stands for “understable” which are discs that are more resistant to fading at the end of flight, which means they are a good choice for beginning disc golfers. The discs in this set are also lightweight, generally weighing 140 – 156 grams, again making them easy to use for new players or for young players. The set includes a fairway driver, a mid-range, and a putter, plus a mini marker disc to mark where your disc landed on the course before your next throw. NOTE: The disc colors and weights vary, with colors usually bright and weights generally low.
