RE: Clarrifier
Depending on how old you are there is another option. If you're in the group that needs bifocals then you can use a "Verifier". It screws right into the Specialty Super Peep. I got one and now I don't see three blurry pins anymore (the sight only has one pin). There are about 5 different diopters and sizes. You could try several to see what works. I got the
#7 lens with 1/8" hole, marked #750-13. I should have gotten the one marked #750-12. Too strong and it blurs the target a little more than I like, but I do see that it'll work. The down side is that they cut out some light and are a bit slaty. I got mine at Lancaster Archery for $25+ tax. It does sound like a lot, but I spend a lot of money on this sport and can't shoot any better than I can see. At 57 years old I need all the help that I can buy.
Hope this helps
