Can’t believe that no one has asked how you’ll be using it. What kind of distances, helmet mounted or just handheld, etc.
If you are going to helmet mount it id say Nox 18 is about your best bet. Especially because of its versatility if you later decide to rifle mount it too.
If you just want a handheld I wouldn’t get the Nox. The 1x isn’t great for looking across fields, etc if you aren’t trying to walk around or drive with it.
I had a cheaper pulsar handheld before the Nox and there are a lot of times I miss the 2.5 native mag if I’m just scanning with it.
Plus, the Nox says it’s 1x but unless you are up pretty close to objects it is more like .7-.8 when you get about 25+ yards away from you. I can open both eyes and the actual object is larger than what I see through the viewfinder. I was pretty disappointed about that.
