There are 5 different PXS Target Peep Clarifier magnifications available. The Clarifier works with a bow scope and lens to help clear up the target, allowing you to pick out target details at a distance. We recommend Lens Brite Anti Fog Lens Cleaner (#641) and Soft Tek Cloth (#642) for cleaning the lenses. The stronger the scope lens, the more powerful the Clarifier needed (See chart below for suggestions). NOTE: PXS Target Peep Lenses require the use of a PXS Target Peep Aperture to secure the lens into the PXS Target Peep housing. NOTE: PXS Target Peep Apertures, PXS Target Peep Clarifiers, and PXS Target Peep Verifiers fit into Specialty Archery PXS Target Peep ONLY. NOT compatible with other Specialty Archery peeps. See Dealer Locator on our home page for a dealer with a Clarifier Tool near you, to help you select the Clarifier best suited to your needs. Additional information can be found in the Questions tab on our home page.
