It think it did Went out detecting to the button hole I have been talking about lately, to see if the GPX could find some of the deeper buttons there. At best I've found buttons at the 6" mark, 7" if they were larger ones. So off I went today early in the morning. Detected about 7 or 8 hours. The GPX was able to get 39 brass buttons and 2 iron ones along with the 3 round ball and the large crotal bell. Plus I am getting better at saying NO to some signals that I think are iron. Cellar holes are tough with the GPX, but after a while you get semi comfortable calling the signals before you dig. Every button today was a plain (no design) button except for 1 small one and the large cloak button. What I was hoping to see at this site is what actually happened. The GPX found the smaller buttons at the 5-7" range and the larger buttons at the 7-9" range. Did pretty good with a couple of deep targets that were close to iron too. That was a bit of a surprise. So the button hole lives on
