The new Pro Series Peep is a sculpted, hooded peep that is 25% lighter than the original Hooded Super Peep housing. This results in increased arrow speed. The Peep accepts all Specialty Archery 1/8" apertures, clarifiers, and verifiers. We recommend use of the 210078 Dual Hex Aperture Wrench for insertion and removal of optional apertures, clarifiers, and verifiers.
