Just mounted a new Nikon prostaff 2x7 on my Black Diamond today. This is my first Nikon and at this time I'm very impressed. I've always been a Leupold guy, and maybe scopes have come along ways in a few years, but holding this next to my 10 yr old Leupold 2x7 this thing is night and day difference in brightness and clarity compared to the older scope. If this keeps up I'll be making more purchases next Christmas.
