I was just reviewing all my gps coordinates in onX and measured the distance of 3.8 miles from my glassing spot to where I spotted the elk in Colorado on day 1. That would have never happened without my 15x binos...the snow helped as well! The next day I spotted them at 2.3 miles scattered among junipers. My hunting buddy had 12x50 razors and was getting frustrated how he would miss game that I would find. Grateful for all the encouragement to jump in and get a pair.
