The Tern is an understable high speed driver. Being understable, this is a comfortable disc that provides max distance for intermediate players. While the Tern’s rim is very wide (2.3 cm) it isn’t at max width like the Dominator, Vulcan, or Katana. The Innova Tern was approved by the PDGA on December 3, 2012. Innova states that the flight rating of this disc in Star and Champion plastic slightly differ. The flight rating for Champion Plastic is 12/6/-2/2. The Champion plastic that the Tern is manufactured in is super clear and looks really sharp.
