The most advanced peep system in the archery industry, completely designed for ultimate accuracy. CST – Center String Technology – PXS Capture Aperture located on center of bowstring – no L and R misses. OCT – Optical Centered Technology – Improved centration of lenses for ultimate accuracy. PLT – Protected Lens Technology – Lenses protected by plastic on 2 sides prevents cracking. DSAT – Dual String Angle Technology – has both 37 and 45-degree string angles on the same peep housing. On the smaller diameter, narrow section of the peep housing, there is a small machined dot. Install peep with the dot in the downward position for 37-degree string angle grooves. Install peep with the dot to the left side for 45-degree string angle grooves. The peep should be inserted in the string so the side with the verifier, clarifier, or aperture is on the side you look through. TAP – Tool-less Aperture Technology – Knurled Tool-less PXS Capture Aperture – eliminates the need for an aperture wrench. PXS Clarifier or Verifier lenses can be removed from the PXS Capture Aperture for easy cleaning. The optional Verifier lenses sharpen the pins. The optional Clarifiers when used with a scope and lens sharpen the target face. Available in Black, Blue, Green, Red, Purple and Silver. Optional PXS Target Peep Shade Cap screws into front of peep to prevent glare. NOTE: PXS Target Peep Apertures, PXS Target Peep Clarifiers, and PXS Target Peep Verifiers fit into Specialty Archery PXS Target Peeps ONLY. NOT compatible with other Specialty Archery peeps.
