Don't let changes in your vision compromise your ability to make the shot. The Verifier has a lens in it similar to those found in reading glasses. Allows you to see your sight pins better on your hunting sight. NOTE: Podium Peep Lenses require the use of a Podium Peep Aperture to secure the lens into the Podium Peep housing. NOTE: Podium Peep Apertures, Podium Peep Clarifiers, and Podium Peep Verifiers fit into Specialty Archery Podium Peep ONLY. NOT compatible with other Specialty Archery peeps.
