The Ringer GT disc by Discraft was PDGA Approved on 4-21-2017.
"It's a beefier Ringer! Your short game will get an instant boost when you deploy Ringer GT. Discraft has taken all the best attributes of Ringer and added a subtle Groove Top that increases grip confidence while shifting the stability of Ringer from 1.5 to Ringer GT's 1.7 rating. Players use it more often for driving and approaching when a soft landing is mandatory and wind needs managing." - by Discraft
