I buried a Merc at 10''s in my yard today as an experiment. I set my at pro on my usual hunting mode. Pro Zero, max sensitivity, 00 iron discrimination, and auto ground balance which landed on a 73. I swung over the target and got nothing. No sounds no displays nada. I then began to manually bring the ground balance down a little at a time. when I got down to 60 I started getting a faint high tone and an 82 vdi and a max 10 inch depth reading. I continued down to 59 and then 58 with the same results. But when I got to 57 and below everything stopped. No sound no numbers nada again. I have dug silver dimes at seven and eight inches but never this deep. I have dug silvers halves at this depth though. Anyway. I got this idea from members and you tubers so thanks to you all for the tips.
