Hunting with my new closeout Quattro (and I am a long-time Minelab user) I found that deeper objects will often signal in one direction. Civil War bullets and coins. Bullets read like a nightmare, even during open-air testing. The shallower items read just fine and do so repetitively. I have this feeling that the ground cancellation programming on Minelab tends to read faint signals and then compensate as if the signal were, in fact, ground mineralization. It doesn't hold up that a one way signal is necessarily junk. I agree with an earlier post, if it whistles, dig it --- if you can do so without cratering someone's million dollar yard!
To this day, the Detex unit I used to dig many a bomb and bullet in the 1980's just can't be beat! Happy Hunting!
