Went to some old house that I have hunted before, got 2.43 clad and 2 wheats. Deepest coin was 6". Had run sen. at 50 because ot the city has a lot of ele. lines. The little coil looks like it is going to work good. The mane thing is you have to walk very slow and that is good too. I'll gove a few more hunts and let every one know what happens.
