i dont like hunting solo at night. to many things can happen. you could step in a groundhog hole and break a leg, trip or fall down a hillside, other things can go wrong besides being injured.
we shared a cut cornfield with a bear one night. it never paid any attention to our prey distress call, sometimes, the things that go "BUMP" in the dark show up.
i have had deer run up behind me and at night they sound like a freight train headed towards you from behind, when that happens and you dont have a light handy, you make some moves that would make Michael Jackson jealous.
you'll be fine as long as you keep the call away from you. Predators will focus on the call and come in with the wind in their face.
