When you get to the SLC series, the jump between grades gets way smaller. I have looked at the same deer in South Texas through my SLC's and the rancher's EL's, and he got maybe a minute more visibility in the treeline than I had. If I had not already known where the deer was, I might not have been able to find him.
He did have an older pair of Zeiss 15 x 56mm that were unreal, but not very handy. Weighed more than double my Swarovski's.
My buddy grabbed the EL's and looked thru my SLCs side by side. The only difference is in the edge of the glass
