Specialty Archery has five sizes of Apertures which will screw directly into Specialty Archery Pro Series and Ultra Lite Peeps with use of the Dual Aperture Wrench sold separately.
NOTE: The peep should be inserted in the string so the side with the verifier, clarifier, or aperture is on the side you look through.
You will need the Dual Aperture Wrench sold separately to insert into peep.
Not compatible with Podium Peep, PXS Peep, or PXLH Hunter Peep.
To select Aperture size: Increase your apparent magnification by reducing your hole size.
