Consider there are many folks who purchased the NL without ever lying hands on them. Lead times have been extremely long with low inventories ever since they were announced. I was fortunate enough to get my hands on a pair of 8x (couldn’t find a 10x) and take them to the field with a few others (Zeiss Victory SF, Swaro EL, Leica Noctivids, etc). My personal pair was a Swaro EL 10x50, which I believed to be the best available glass to my eyes… and after a few times evaluating them all, I decided the NL Pure was my personal favorite. I had to place an order on 10x and wait a few months to get them, but overall I find them to be the best pair of Binos I’ve ever laid hands on.
All of these binos are what I’d consider top tier, but each has subtle differences. The fact that I prefer the NL doesn’t mean others will, but to me they’re simply the best of the best.
So all of that said, I think you could look on the used market and find all of the above products for sale… which doesn’t mean anything about their performance or lack thereof. I put my ELs up for sale immediately, and went through a lot of effort to previously decide they were the best fit for me. I hope their new owner appreciates them as much as I had.
