This disc is NOT approved for PDGA sanctioned events.

One of the most controversial discs in disc golf. As the name suggests, this disc is designed for disc golfers who Turbo Putt. Turbo putts are executed by holding the disc like a waiter would hold a tray, with the fingers on the outside of the rim and the thumb under the disc towards the middle. The edge of this disc is like a "saw blade" that allows you to lock your fingers into the rim. The bottom has a swirl pattern that is engineered to adjust to the different spots that different players would place their thumb. It doesn't have a lot of glide, but seems perfect for what it was designed for; short range turbo putting. Beaded Putter.
