Same way as when you use a rifle just don't shoot them when you first see them. I do not use a E caller too much trouble. And my decoy if I use one is not in sight till they are close in. Its there to make them stop not to attract them. Seen way too many just sit down at hundred or more yards out just look at the decoy. But also had a couple take my decoy. Any distress sound will work from chicken ,mouse, deer, cat, squirrel and the best is rabbit or dog. (Don't spend too much time in one stand maybe ten to twenty minutes maybe thirty some times. then move on and make sure your stands are 1/2-3/4 of a mile apart or farther. Just go do it and keep trying. Sneeky, sneaky,sneaky. You want to make them think that your dinner so they come to you .
