Try a cell phone but theres usually no signal. If I'm with some one ,we've decided to fire a volley of 3 shots. If I'm by myself,which I mostly am, I remind myself to stay calm. You could follow a creek bed, walk toward the sun, or try to find a trail and stay on it. My grunt deer call made by Primos has a built in compass which I've used before. I love those guys.
