I bought a well taken care of xs on ebay and was playing with it in my yard using the stock coil. I have a Safari, but I can tell that I am going to like this machine just as well. Using ferrous sounds I found three wheaties in less than 30 minutes. I was operating with no discrimination to hear all the sounds. She played a lovely tune. LOL! My only problem so far is pinpointing. I've got it down with the Safari and I am sure I will get it with the XS with a bit of practice.
