Took a drive tonight to an older school in Portland where I have had a little success in the past and decided to swing the Explorer SE Pro over a small patch that I covered pretty thoroughly with the CTX in the past. Got a faint signal at about 5"... 40's Wheat. Then a more solid signal at 6"... 2 wheats in the same home (one 40's, one 50's). About 10 feet from the mini pocket spill, I get a really scratchy signal.. 6-8", I can barely hear a high tone peeking through. At about 7"... a beautiful green 1902 Indian Head pops out of my hole. My first IH and my oldest coin so far. I am really enjoying this Explorer!
