I just bought a used Pro so am basically learning and love it. Enough that I bought a new one, as they are not making them any longer. I shouldn't have a problem selling the used one as it is an excellent machine.
Well this past Sunday I got out to an old site where there had been a stage stop and Hotel (1857-1869), found this beauty of a ring. Very old!! Since gold wasn't marked w/karats until 1906 it is unmarked but definitely not plated. Appears to be a garnet or ruby. I got a reading right square under the nickle mark. I would like to know if anyone has hit a gold coin with the Pro and what numbers they hit at.
