Thanks Darren and Elton It just shows how naive I am about metal detection ! I never used one... But I am surprised that my post didn't get more response, as well as the ones from Darren that I mentioned in my first post: 1- Possible Ohio crater in Apr. 2005: not one response to it ! Another

depends on machine and operator I suppose. These are quite expensive tools, and I just discovered them a few days ago. They are used in mineral prospecting, and will do elemental composition in ppm I think. Bill Hall
