Wind or sound to hide your noise? Do you not think a coyote can tell the difference between "near vs far away"? BTW, I've tried what you refer to. Works better on Red Fox, rather than coyote.
A few yrs back, there was a large gray nomad coyote. That kept laying on a pr's territory. This coyote, never laid his head down, that I ever witnessed. Always on alert, head up panning 360. I seen him 4x over a wks span. Coyote kept laying in almost the same exact spot on a hillside. Coyote panned around often, looking behind[upwind] of where he laid.
I tried 3 or 4x? stalking in on him. I quartered into a stout 20 mph wind on those days. Coyote busted me every time about a 1/4 mile away. Coyote never seen me, but knew something cometh his way. He was sitting up ready to bolt. As I slowly crawled to the top of the last hill to get a long shot on him.
Last stalk, I was already prone & ready to made a quick shot. I grazed his shoulder as he turned to bolt. Never seen him again. Yeah, noise... The farm I parked at & walked/crawled from, to this coyote was in a straight line. from this coyote. Farm was loud with machinery & a corn dryer making background noise.
Coyote heard my footsteps crack a few frozen bean stubbles. A 1/4 mile from him, while I was nearing the top of the hill that separated us. Coyote was eyeing me, as I crawled to the hilltop for a shot. I was on my belly.
A hunter might be able to use loud background noise on a yearling. An old dog, he'll play heck getting close.
Red Fox, don't hold a candle to hearing a hunters noise compared to a coyote. A Red will often go back to sleep. Even though he heard the hunter. A coyote on the other hand will be on alert, or gone. He knows your coming.
