"DADDY"
@sndmn11 Are we using tunneling the same way? I had understood tunneling was when the field of view stops changing before you reach the end of magnification adjustment. Ive seen it most often on the low power where fov stops getting wider at (for example) 4x, but the scope magnification still goes down to 3x. You said “picky”, so Im wondering if you are referring to something different?
This was a boating forum and it was a random question—no one there is talking about the scope, it was something he had heard elsewhere (unspecified).
I think of it as a significant black ring around the FOV that changes size as magnification changes and that looks like seeing the interior of the rifle scope.
I perceive it in the same manner as the eye box because I haven't used any scopes that exhibit it terribly. So, my "tunneling" seems to be different than yours and most likely most people's definition. Regardless, I don't see my definition or yours, Cindy, and the kid didn't have any difficulty behind it either.
