I'm sure some of you have probably experienced this, but it happened to me a few times recently for the 1st time that I noticed it. I was getting an Iron reading -10, however it didn't sound like iron was a higher tone, so I dug it and to my surprise I found a nice Indian Head Penny in with the Iron. So if you get that Iron reading but it doesn't sound like Iron DIG IT.
