Well I have been doing some research. I found some old county maps from the 1820's 1864' and 1871 of the county I live in and some from the surrounding counties. Saturday we took a trip to a old church site from the 1730's era. I only found one coin but it was a 1841 large cent. This afternoon I went back to the place I found the 1781 Spanish reale, looked about a hour. Had the sensitivity on 26 and auto, gain up a couple of numbers, got a small signal, high pitch, right hand top corner, meter was at the very bottom of depth, the pinpoint I could just barely hear, but it was there. I dug and checked, still in the hole, dug some more, still in the hole, down about 9 inches in the Virginia red dirt popped out a 1797 Spanish reale, two found since I got this Explorer 2, about 3 weeks ago, only been out with this thing 5 or 6 times. I like to have fell dead. Never found anything like this when I had my XLT. Back to the maps for me.
