The Clarifier works with a bow scope and lens to help clear up the target, allowing you to pick out details at a distance.
The 1/8″ and smaller Clarifier works in all standard size Pro Series and Ultra Lite peep housings.
1/8″ and smaller Clarifiers will also work in the 1/4″ peep housings, but the Peep Reducer (#753-3, included with all 1/4″ peeps) is required for installation.
