That's what I do to. Works great.
The deerget interested in the source of the sound, but sinceit sounds like an animal, they aren't spooked. I try to start the sound with an 'm' or 'n' to take the edge off of it.

If you're going to stop a deer. be ready to shoot almost instantly. They can be pretty good at locating you, and you don't want to shoot after they know what you are.
