Alchemy, yep I've read it, and read it on the treasurenet forums...but it wasn't real to me until it happened. I do well with coins and silver; however, to get the gold you have to be willing to pull up the trash. Yesterday it was totally worth it. In the future, I will probably determine the hunt by how much time I have on my hands. For an hour or under, coin and silver mode. For anything over an hour, I will invest in gold hunting with little discrimination, and higher sensitivity.
