The most advanced peep system in the archery industry, completely designed for ultimate accuracy. CST – Center String Technology – Podium Peep™ Aperture located on center of bowstring – no L and R misses. OCT – Optical Centered Technology – Improved centration of Podium Peep™ Clarifiers and Verifiers for ultimate accuracy. PLT – Protected Lens Technology – Lenses protected in the peep by plastic lens seats on 2 sides to prevent 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 Podium Peep™ Aperture – eliminates the need for an aperture wrench. Podium Peep™ allows for easy removal of Clarifiers and Verifiers for 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, Pink, Red, Purple and Silver. Optional Podium Peep™ Shade Cap screws into front of peep to prevent glare.
