20 centavos silver coin this morning with the F70. Looks like it was once part of a necklas. The coin was within an inch of a bottle cap and still was able to see both signals. Praying for rain so the ground can get a drink, it's so hard to dig. Running the same modified coin settings as yesterday disc 22 sens 60 thres -3 machine is very quite and stable even in the can slaw.
