I detected an old ball field that is now a soccer field. I have been hunting this spot for ten years and anything other than clad is non existant. I set my disc to just below nickel and was digging everything while trying to tell if the signal was coin or junk. I was over 50% going by just how the tones sounded. I did not move the disc knob one time in this field. I dug 25 coins from the surface to 8 inches deep. The two deepest coins were wheaties and were nice tight, but faint signals. I doubt that I could have heard them without phones. This old Tesoro is as good as any beep and dig detector I have ever used.
