In particular, Appomattox. My wife's father bought a house out there a few months ago. He's on 10 acres near the town itself. I took my Detector pro PI this weekend thinking I would be good. It went nuts on the normal settings. I played around with the frequency and tune quite a bit, but there was still heavy interference. Supposedly, PI's are supposed to handle it all. I might not know the machine well enough yet. This is the first land trip I've tried with it, normally it's all beach and water, no problems there. My backup is a BH IV, it didn't do much better. I dug down about 4 inches and hit a bunch of small broken up rocks. Are these hot rocks? Or is the combo of the soil and the rocks messing with the detector. I'm up for buying a decent land machine this summer because I think their property has some potential.
