Yep. Yesterday I pulled a Washington quarter at about 9" usinf the 17" coil. No sound but the 12-48 flashed for a second. The ground was very dark, muck like. My friends GTI 2500 could not pull it. Ditto with the DFX.
Go as slow as your patience will allow and you will find more.
I really surprised that you didnt get a sound. I have pulled steady tones from 12" deep quarters. I realize that soil matrix makes a lot of difference, that's a lot of difference.
