PXS Apertures available in 5 sizes (1/32, 3/64, 1/16, 3/32, and 1/8). 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 PXS Capture Aperture located on center of bowstring no L and R misses. 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 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. If you use a 1 3/8, or Versa scope, try the 1/32, 3/64, or 1/16 Aperture. If you use a 1 5/8 or the Versa scope, try the 3/64, 1/16, or 3/32 Aperture. If you use the Super D or Versa try the 3/32, 1/8, 5/32 or 1/4 Apertures. NOTE: for larger scopes you may also want to consider one of the PXL Hunter or Large Peep Housings.
