The most advanced peep system in the archery industry, completely designed for ultimate accuracy. Capture Aperture technology uses LRT Lens Retention Technology to prevent dropping of Verifier or Clarifier lenses! Increase your apparent magnification by reducing your hole size. Select an aperture size that will fit tightly around the scope housing when looking through the peep at the scope while at full draw. If you are using too large of an aperture, accuracy may suffer due to improper alignment of the scope and peep. If you are using too small an aperture, you may lose some field of view of the scope lens and restrict the amount of light, making for a dim sight picture. CST Center String Technology PXL Hunter Peep Capture Aperture located on center of bowstring no L and R misses. TAP Tool-less Aperture Technology Knurled Tool-less PXL Hunter Peep Capture Aperture eliminates the need for an aperture wrench. PXL Hunter Peep Capture Apertures allow for easy removal of Clarifiers and Verifiers for cleaning. If you use the Super D or Versa try the 1/8, 5/32 or 1/4 Apertures. NOTE: for larger scopes you may want to consider one of the PXL Hunter or Large Peep Housings.
