I was metal detecting in the old park yesterday and came across an area that was absolutely full of iron, or so I thought. I got a decent signal and dug up a bunch of coal. The coal was very close to the surface and there was a ton of it. There was also a clad penny in there.
Does coal cause a detector to go crazy? The area was about 50 by 50 feet.
