Kajunoutlaw, if you look at the "banners" above, the Confederate plate on the far left was found with an AT Pro recently. I was standing 10' away when it was found. Soooo...that question is answered. I also did well but we were really working a small part of a field and it was on "his" side.
One thing of note, I don't waste my time in overly hunted parks. You do need an "edge" there, if you can ever get one, but, again, until technology changes again, that "edge" will disappear in a few hours as other people with "your" machine have already hit it. I noticed about 5 new Equinox's in my MD club in the same park(s). The "edge" is now history.
It's location, location, location. I was looking at three new properties just today. Guys, just get away from the computer and go dig. My next dig is in about 36 hours. Then another flight to dig, then a beach, then another flight, then the ground will be warm here. It tried to thaw today. Didn't quite make it past 2" deep though. There are days I wish I could find a machine that would really show me something, but for now that day has come and gone.
