The Verifier has a lens in it similar to the ones in your reading glasses that will allow you to see your sight pins better on your hunting sight. Don't let changes in your vision compromise your ability to make the shot. The verifier lens sharpens the picture so pins and quarry are easy to see.
The 1/8" aperture is available in #5 (purple mark) verifier lens. The 1/8" verifier is for use in the 749-37, 749-37H, 749-45, 749-45H, 749-37PS, 749-45PS, and 750-1 peeps. It will also fit in the 749-37L, 749-37LH, 749-42LH and 753-1 peep with aid of a screw in reducer (753-3).
We recommend use of the 210078 dual hex wrench for inserting verifiers into your peep. We also recommend Lens Brite Anti Fog Lens Cleaner and Foam Applicator Lens Cleaners for cleaning the lenses.
CAUTION: High powered bows create a great amount of vibration. This may loosen verifiers, clarifiers and apertures over time. Tighten your apertures before each use. If you hear a buzzing sound, this indicates a loose aperture. You may use a drop of the blue Loctite or Vibra-Tite VC 3 to help hold the apertures in place.
