Got my coil over this nice Barber quarter while using my Legend with the stock 11 inch coil. It was only about 4 inches deep but there were 3 rusty nails in the hole with it, rang up on the vdi at 32-33 loud and clear in both directions and I think it was still there because of the lower numbers, I thought it was going to be just another pull tab but I got a big surprise as you can see. : ) It might have been on edge or the nails might have dropped the numbers. I kept thinking how many guys walked over this shallow Barber with their detectors thinking it was just a pull tab because this park has been heavily hunted. My settings were Park mode, M2, ferrous disced, recovery 8, IF 3, ST 3, 60 tone, my gain was at 25, firmware version 1.09. I also dug a couple deep Indian heads in the same hunt that were length of the probe using the same settings.
