I echo the good glass advice. Bring a spotting scope or some 12x Bino’s with a tripod/shooting stick that you can stabilize them on. Get to some places you can glass morning and evening (the heatwave distortion during the day can make it tough to glass the distances you may be looking, if you happen to get a very cool or cloudy day, use that whole day to glass for sure!) it may take a bit to find deer pockets and then a little more time to find some bucks but once you locate them it will be much more enjoyable and less frustrating than blindly stomping around through the whole unit.
You’ll want to look near water, tall sage, buck brush, pockets of juniper, bedding areas off of alfalfa fields, bedding areas around rim rocks (especially north facing and east facing) it really depends on where you are hunting in the unit what you should look for ( some areas in the unit have almost no sage or juniper; if you are near the river, water will be less in demand, etc)
Desert bucks are very cagey they will often find a pocket that they like and will stay there as long as they can and will just move no more than 500 yards from that central location until big rains, cold weather or the rut. Good luck!
