I have been experiencing my eyes becoming blurrier when looking threw my peep. This has been going on for a few years now. I went to a single pin so I only had one to pick-up with no confusion. It helped, but I could not pick a spot on my target to focuss on. (Aim small miss small). I really noticed it in league. I could not see the X. On a deer I would just shot above/back of the forleg centered on the animal. I would of liked to of pick-ed a spot instead.
To make a long story short my pro shop (Brians Archery) fitted by bow with a bigger peep and a clarifier. It does not magnify it just clear things up at a distance, not a the pin. That would be a verifier. So far at 20 yrs in the shop and 16 yrs in my basement thing are looking good. I have not used it outside on a target yet. The verifier did nothing but make things blurrier. Does anyone else use one or can add to this subject?
