I had EL 10x42s as my primary binos and got the 12x NLs mostly out of curiosity (how much better could they possibly be, right?)
Man, the ergonomics and weight coupled with the FOV and image quality…they were worth every penny. And it is a lot of pennies.
Used on an Outdoorsman’s stud/pan head I can leave the 15x SLCs and/or spotter at home much more often. Handholding them with the head rest they’re as stable as the 10X ELs.
I keep the 10x ELs around as loaners, I ain’t going back.
