Like it was stated above, I can't imagine being out in the desert without a binocular. I've gotten to the point where I strap my Snuggle Buddy (Alaska Guide Creations chest rig) on for pretty much every hunt, including predator hunts. I keep my 10x42 bino, rangefinder, GPS, camera, wind checker, hand call, spare batteries, mini tripod, and optics wipes in it for easy access.
I almost never use the bino while actually calling, that seems like a sure-fire way to get caught with your pants down when something fuzzy comes streaking in. But, at the end of each stand, I typically glass around to see what's out in the desert, either way out in the flats or in heavy brush nearby.
I suspect I use the bino more for non-predators though. There is a lot to see out in the wilds we hunt. I love to glass for deer, antelope, oryx, and other wildlife. I like getting closeup looks at feeding raptors. I like to glass distant objects and/or people safely (no rifle scoping).
In short, being able to see farther and clearer enhances the hunting and outdoor experience. Heck, I don't even go fishing without a bino these days.
