What I am seeing on the etrac is more of an iron issue then depth, at least I think.. Havent gotten anything real deep yet but the couple of coins that I did get and both were about 6 inches where they numbers stayed low were in iron.. At 20 and a 23 ferrous.. they would bounce up, but werent bouncing down.. thats why I dug them.. I am finding the falses from iron that bounce up into the coin range are the off edge falses from iron, and switching to quick mask wide open you will see the target is off center and drops back down where it should be when you center it.. and I gotta tell you a nail sure sounds good when accepted

No more will you have the highest tones coming from coins like silver.. nails sound more like coins did on teh explorer.. the expanded conductivity took care of that and I guess that can end up being a good thing.. that iron is giving you the highest tone so maybe can be ignored easier.. however it s the off edge falsing that will be confusing in patterns, they seem to come in at 42-46 cond area.. they dont read solid, but make you investigate closely and do sound similar to one of those deep coins at the edge of detection.. even the depth meter has them buried.. anyway to answer I think your safe opening that coin area of maybe 40-46 down to 20 as long as you keep it slow in high iron.. I realize this machine is supposed to be faster but if you go fast you seem to get alot of those quick high tone falses and have to stop anyway to check them out.. the easier targets will hit more soild. a faster sweeps speed. so I guess moving along faster you can pick off those easy enough.. that was true with the explorer as well though..
As for comparing to an explorer, yes I have had coins in iron(maybe not a quarter that I can remember though) mostly indian head and that sized coins read far left.. probably as far as they are going with the etrac, not often but I have had a few that read top of the screen or in area they should be but left of center, and were even giving solid low tones in ferrous.. audio quality was still there though.. and they should be dug no matter where they read if they sound round.. at least on the explorer..
And one thing to remember is they altered the ferrousity on some targets, on the etrac so a head to head comparison to what each one will do, is not really true.. if you know what I mean... coins that were in a total other ferrous range on the explorer like quarters and dimes may not get affected as much as one being told to report something different than it is, or as least was..
quarters at ferrous of 0 or 1 , may not move into ferrous range as far as they would when they report a higher ferrous value than they did..
Who knows maybe they were reporting false values on the explorer and they just let stuff fall where it will on the etrac.. Ferrous value is probably just lingo anyway.,. there is no iron in a copper or silver coin, at least I donnt think there is

and there is iron in crown caps, but yet they read way over to the 0-1 ferrous range.. I never did understand them.. if anything you would have thought they would fall bottom left and not right
They rounded out the sounds so well on the etrac, the trash sounds a bit better than it did on the explorer, at least maybe till I get can get an ear tuned to it.. tough with the switch to conductive mode.. If I end up keeping the Etrac its going to make the switching a relearning experience each time I take the other one out.. as I know I prefer ferrous on the explorer..
And even with the change to the 12 readings which I think would be easy enough to live with, I just don't understand why they took away the multi sounds in ferrous,, at least the iron would mostly low tone, and I guess it would be real easy to tune into the sound of 12 ferrous where most good stuff falls. while being able to run in an open screen with just most iron knocked out.. oh except those pesky crown caps they let run wild on the screen
I f people dont like multi tone ferrous, then the other options would still be there.. please give me back my ferrous audio
