I went to a house that had burned down and there was so much melted aluminum that I turned my discrimination up to where it would knock out pulltabs, small aluminum pcs, etc.
The hunting was very hard but I was able to find a 1930 British large cent, '64 Merc, '04 Barber dime, melted silver coin, a worn silver coin, 3 wheaties and 2 memorial pennies. I checked the melted coin and it
came in on a Teknetics 8000 at 85 like a mercury dime. The worn silver came in at 97-98 on the same machine. With the discrimination at maximum on the Vista X, it still would not discriminate the worn coin out.
I ran the disc at 38 with the iron volume off... The detector was noisy with all the crap in the ground but when it hit a good target, you knew it. I have been over this ground with other detectors and I missed these.
