I was in factory coin with deep mode on . I hear that the etrac is better in bad ground with iron than my dfx is that true. The ground is half frozen and half mud mabe thats the problem.
Spike...The E-Trac doesn't have any ground balance control. It's all done magically (digitally) The ground alone, if mineralized can cause the threshold to go away.
Don't bother with that, just go slow and find the goodies.
