if depth meter is over 50% and target is coin sized and sounds good I get excited. I would say average silver around 6"deep although meter is only reference and not exact always. 1/3 of hunts yeild silver for me.But that all depends on sites and time. Also I have found clad suprisingly deep,usually if meter is 50% or less its probably clad but than id is pretty good on shallow targets.Some deepies sound iffy and im sure I have missed alot, I guess Im still workin some good sites and when I think Ive cleaned em up good then Ill start digging the deeper signals that sound iffy.I'm perfectly content with the EX and never found silver before with other machines, probably because ID is pretty good on this thing and I know when not to dig.With other machines i dug lot more junk. Here is what I use other than IM, Clear screen, X nails and/or crowncaps, Ferrous sounds, Audio 1,manual sens up,and a few other adjustments that you will try along the way but I dont want to overload you with those right now, like fast on deep on var. tone gain blah blah blah. I make minor changes according to junk in ground at different sites.These are my opinions and you will find yours.Good luck,sweep speed average moving forward slowly.
