Well you should be able to hit your anchor with your eyes closed because it should be the same
position everytime. If you have a good anchor you can feel the right spot. But I understand what
you are saying. You can't see thru your peep. It sounds like it may be turned wrong or something.
Many hunting shots are taken in low light so you definitley need to fix it. I just cant picture
what may be causing this. Maybe someone else will chime in.
