Caveat: I've not hunted the desert / open terrain. But some people who seem to know what they're talking about like "big binos" instead of a small spotting scope, for spotting game. I'm not talking huge, like 70 or 80 or 90mm, but "big" - 50, 55, & 60mm objectives, and *quality* - the usual suspects of Swaro, Leica, Zeiss, Brunton, etc - and go ahead and still use the tripod with the binos (or not - either way) - the binocular vision with a large objective and high quality glass does really enhance ability to spot things, supposedly - and plus you then carry one optic device instead of two, saving weight. Oh, the magnif on these should be in the very high range (12x to 15x), but a 10x would work, too....the glass quality is more important than the magnif. I dunno - I would defer to others on this.
