Just as a side note to all of you AT Pro users, the ground balance can be manually adjusted. I discovered that in most if not all of the soil I have here, manually ground balancing the machine leaves me anywhere from 80 to sometimes 95! If you come upon a real iffy signal I suggest turning the ground balance down to 65 or 70 for cross sweeps. Not only will you get greater depth but a clearer signal as well. You may dig some iron but that's the way it goes.
