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.
 
Halo Star is a decorative blend of Star plastic featuring a colorful halo design where the rim is a distinctly different color than the center plate of the disc.
