I found a 9 lb. cylinder of solid brass, looked like it came from a bulldozer or some piece of heavy equipment. It was about the size of a oil filter, but longer & wider. Gave off one heck of a signal!
Someone asked that in another post, like I said there's someone who found a WW2 tank while detecting. The thread is somewhere in the treasure in the news forum.
My biggest find was never dug up. Just too big a signal. Was "L" shaped and measured over 12 feet one way and 14ft the other. Probably a big pipe so not worth digging up. I went down a little over a foot and hit rusty dirt and then quit.
Strangest, yes,yes. I was working the beach of Indian River Inlet in DE after a big storm. I was using my XLT and got a big signal. It was about 1' in dia. I dug down About 2' and found a Navy style anchor and recovered it. I double checked the hole and got another signal. Let me say here that the rope on the anchor went into the hole. I dug down a little more and found the signal. It was the bow eye on the boat. I just cut the rope and filled the hole. Frank
