Really put the MD through its paces I want to try and get it to mess up . I know that's not the normal thing to do but I was seeing if it would lose communication, the only thing that happened was once the pinpointer lost it . So in changing to different programs as many times as I did it turned out to be a good day found a silver ring which was a total surprise for where I was hunting and then the 1905 barber dime which I almost missed if wasnt for dropping my pinpointer also found 7 wheats from the 50''s I think I haven't cleaned them . But I'm going to try and get out again this afternoon . I'll play with posting pics when I get minute not very technology savvy
