I found this at an old house foundation. We had done it many times before and we had never found it. It was about 6 inches deep. I think the reason we had never found it before was that after I dug this, I rechecked the hole and at about 12 inches was an old purolator oil filter that for some reason looked brand new. I figured that maybe by using the small coil I was able to pinpoint them independently.
