[QUOTE="Hookman, post: 7931789, member: 99642"]"Okay, yeah, I'll admit the APS was over the top." I may be guessing low at the cost of a handheld, but you did get my point about the subject of discussion. I read as much of those links provided, as I could in the time I had, and after reading the cpl's link, I clicked on a continuation link in that one, and if I understand it correctly, it states that it can go completely through some items that are not too thick, and will "report" back along the way what elements it finds. It really depends on the thickness of the item and the intensity of the beam. Remember, most coins are not extremely thick. If I remember correctly, It was the second of his first two links that I followed through another link and it was in that one that I read the info about 'depth of discovery'. Please read it for yourself and see if you understand it the same way I did. Be all, and any, of that as it may, I am very comfortable trusting the results of an XRF gun scan to tell me what my coins are made of.[/QUOTE]
