Took my Ace 250 out behind my house where there are a lot of woods. Hunters have been going through there for years. I set the sensitivity at 4 bars, put it on all metal. Every now and then I would get it registering iron/foil, sometimes with one ding, sometimes a double. I pinpointed with the Ace, found the best spot and started to dig. Well, I dug and dug, cut away little roots that were growing everywhere underground, kept checking and rechecking the spot. Didn't find a thing. When I was done I had dug 5 holes that before I filled them back in just kept getting bigger and bigger thinking that somewhere in that hole was something waiting for me to find it. But nothing!
Then I decided to walk around the new addition and see if we had missed any screws or nails. Now those I found with no problem. At least a dozen of them Including a bit for the electric screwdriver and a penny. But what was it trying to tell me out in the woods? Should I use discrimination and cancel out the iron/foil? But then I read that sometimes silver and some gold rings show up at foil. When I put it in the relics mode, or ANY other mode I got no signal there. Should I not hunt in the all metals mode?

Some of us have a Pro-pointer or some other hand-held locator. So we are spoiled big time. Like they said, you probably just missed it. Keep at it..you'll be plucking coins before you know it. It may help to try it out at a park or beach or playground first. I found a 1927 Peace Dollar less than two weeks after I got my Ace 250. Best of luck.
