My opinion is that binos are for spotting and spotters are for evaluating. I’ve spotted deer at 2mi with 8x42’s. This was my first season with 10x42’s. 10’s have an edge over 8’s for wide open country. In canyon or brush country sometimes I feel like 8’s are too much. There are things I need to pick apart that are too far away to pick apart with my eyes, but the field of view is so narrow, even with 8’s that it’s hard to look at things that are close than some distance. With 10’s it’s even worse.
How far can you spot deer with 10x42’s? Over 2mi. How far can you really break down antler quality at 10X? Maybe 400-500yds. Maybe. back to just spotting game, I felt like from 500-600yds+ the 10’s were a big advantage over 8’s. A tripod will help at any power, but 10X is not enough power that a tripod becomes necessary.
.98 mi with the 10x42’s that I bought used for $75. Zoomed in on the video I took through them with my phone and took a screenshot. The visual was better than the phone video.
