IF you've never hunted them I might have a tip for you, if you have hunted them before you already know this. I've only had one tag, I killed a nice buck but I know so very little about them that I almost don't want to write this because I'm sure you know it, but if you don't then maybe this can help.
Some buddies and I drew tags years ago (mid-90s) by San Manuel. We went down there found a spot threw up a couple tents and spent the next 3-4 days walking our tails off without seeing one Coues. We were seeing mulies, desert sheep, mt lion, and pigs but no Coues. Each morning and evening I would see off in the distance, a guy sitting on a hill by his 4-wheeler. He never left the 4-wheeler just sat on the ground looking through his spotting scope. All this time I'm thinking how lazy this guy must be and he'll never kill a buck sitting there. Then one of the evenings I ran into him coming off the hill and dang lucky for me and my buddies, he stopped and visited. He kindly asked if I'd ever hunted them before which I told him nope. He then said that everyday he would watch me hiking around missing unseen Coues bucks within 100 yards of me. He asked if I wanted to meet him on the hill the next morning and he'd show me some bucks. Short story.. the next morning 30 minutes into spotting he had me a nice buck spotted a mile away in which I killed an hour later. Plus with the info this guy gave me my buddies both also ended up killing bucks. All three were nice mature coues bucks.
I'd dare say that which out this guy helping us we probably would have come home empty.
So find a nice spotting location in the shade, lay out your snaks and water, make yourself comfortable and glass, glass, glass.
