I got a new detector a few weeks ago and have been learning it. I've not really got to hunt my better sites due to it being summer still. But this machine is a Pulse Induction machine...which I don't want to get into that here, but they do better in heavy iron dirt...which is what we have here in TN. And it has been showing. These finds have came from a few of my most "hunted out" sites. I am starting to really enjoy the machine now.
