There are 5 different Podium Peep Clarifier magnifications available. The Clarifierworks with a bow scope and lens to help clear up the target, allowing you to pick out target details at a distance. The stronger the scope lens, the more powerful the Clarifier needed (See chart below for suggestions). 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.
