Got out with the Cibola for about 5 1/2 hrs yesterday at a local park there is so much trash there that I didn't even try to look for nickles or jewelry, disc was maxed out, sens was at 10, and the threshold was all the way over, ended the day with $4.84, I thought I had done real well on dimes (17) until I counted all the pennies (39) all but 3 of them are copper the three zincs were surface finds.
