spot and stalk mulies in sage brush country, as well as speed goats, this has come in handy. I even got an elk this way several years back, he came in on the wrong side of a deadfall I was kneeling next to. Though it isn't a true laying down flat.... I lay flat on my belly then pull one knee up against my chest, then draw horizontal. that helps me be more stable then with both legs flat, and its still very low to the ground. IT works good And is surprisingly accurate, though always to the right at first.
