I used the No-peep for a couple years and it helped me finalize a very consistent anchor. But during my last hunting season with blowing rain and snow the no-peep was rendered useless because the front lense got all iced up or obscured by rain so I got rid of it and went back to a peep. I' m still reaping the benefits of a consistent anchor because of it and for that I' m gratefull, it was worth the money. The new no-peep has a recessed (sp?) lense to help keep out rain and snow but I' m not buying it. Anyone know of any pro' s using it?
