These discs glow in the dark after exposure to light! (UV lights work best)
Tern is a fast slightly understable disc that is designed for long shot shaping throws. In the hands of a powerful player, it just may be one of the farthest flying discs due to the long glide and natural turn. The Champion and Glow Champion Tern flight numbers are slightly more stable. (Star or DX are 12 | 6 | -3 | 2 )
Best Choice for: Shot Shaping Driver, Great Glide, Out of the Box Roller
