Clarifier with 1/4" Aperture with #1 Lens (yellow) For the target shooter there is now a 1/4" hole size. The clarifier will make the target crystal clear allowing you to pick out the details at a distance. The larger opening allows more light transmission than our standard 1/8” clarifiers for better low light shooting. This clarifier is also designed for hunters using a lens in their pin sight. The clarifier will work in the Super Peep 1/4" Housings (749-37LH, 753-1, ans 749-42LH). See FAQs for suggestions in picking the clarifier best suited to your needs. We recommend use of the 210078 dual hex wrench for inserting clarifiers into your peep. We also recommend Lens Brite Anti Fog Lens Cleaner (Part 641) and Foam Applicator Lens Cleaners (Part 501) for cleaning the lenses.
