Hi I have a 8x scope. I need a clarifier lens and peep housing. What would you recommend?It is really hard to know on both accounts. If you can make it into a shop you can test it. The size of the aperture depends on a lot of things - length of bow, sight length, scope width. Years ago smallest was the way now the holes are getting a lot bigger.
The #3 clarifier is recommended for 7 and 8X. I would start with a medium size hole.
