We recently discovered a country school (1893 - 1967) that has been untouched by any metal detectors. I have two machines, a mine lab XS and a T2. We were there for only 1/2 hour and I pulled out 6 silver coins and 8 pennies, the oldest going back to the 30"s and the newest being 1962. Every coin I found was at the bottom of the plug which was between six and eight inches. I was using the mine lab XS and soil is quite sandy and moist with the melting snows. I was just wondering if the T2 would go deeper using Thomas Dankowski's program for the T2 ( disc setting 0, sensitivity Max, two or three tone ) There has to be older coins there but I think they are deeper. Any suggestions for either machine for the deepest detecting would be appreciated.
