One side of the old 1880 era stone school yard is solid coal cinders/slag and is about impossible to hunt but I found a few targets.None were over 4" deep and most were about 2"-3".
I was running in auto at 5 to 7
and the signals were iffy at times and pinpoint was tough but I now know it will work in those terrible cinders and it is the first non-PI machine I have found that will.
The E-Trac became a silent machine as a constant null most of the time.The site is close to home and it sure beat not going at all,Ray.
