I’ve used the Swaro 12x NL Pures for the past 3ish seasons primarily for mule deer. If I could go back and buy again I’d probably get the 10x version for the wider FOV. The 12’s are sweet, but I don’t think there is much that I can see at 12x that I couldn’t pick up at 10x. IMO high power binos (15x+) are a pretty niche product for very long distance glassing. They can’t give me the detail I get out of my spotter, and can’t be handheld near as effectively as lower power options. Keep in mind that things like dust, smoke, fog, heat, and the angle of the sun can degrade the image in your optics, rendering them almost useless at range in certain conditions. At the distances where high power binos start to make sense (1 mile plus?), you will need almost perfect glassing conditions.
