I was making out the depth on my etrac today.. I basically found an old coin spill including a few silvers.. Most VERY deep..
I noticed that my FE was going to 0 even on a deep nickel and CO was still high.. So this is a very good tip!
(That may have been the silver war nickel I found)
What do you think about threshold nulls on targets that are even deeper yet?
In the same place I dug all these very deep coins, basically a coin spill including a silver quarter, couple silver dimes, silver nickel, bunch of wheats etc..
I dug everything I could get a decent lock on with the etrac, even went through setting testing everything I could think of to try to eek out a touch more depth..
I got it to give me a few more unrepeatable 01:27-50 ish signals that I’m sure are more coins I just can’t get a lock on, and even more threshold nulls in this same spot..
I’m going back with a real shovel and am going to do some real digging..
What do you think about these threshold nulls? They seem repeatable..
Also.. I got a couple of barely repeatable signals, dug them, and then once the hole was 8-10” deep the signal would disappear..
Do you think the etrac can possibly detect slightly better through dirt than air?
Therefore I can barely get a tone with depth meter pegged deep, but then once I dig the hole the tone goes away? (Hole still too small for coil)
I think that’s what happened to me a couple times too..
Pretty sure it still gives a threshold null over the holes though..
I’m talking threshold nulling with no mask/discrimination on at all/all metal mode..
Nulls similar to if it was discriminating something with a mask on, but nulls with no mask on at all..
I think it means a very deep target..
I’m going to find out…
I’m gonna go dig like 4-6” of overburden off this entire area and see what happens..
This thread has some commentary on what I’m talking about..

I also may take a big 18” coil with me there and see what that does first..
This was with a s.e.f coil by detech.. 12x10 I think..
I have a big 15” or 18” excellerator E coil by detech too..
And I think another in between..
This is NOT the place for a big coil, this is basically in the woods..
But this one spot is very clean except for these coins..
I might be spazzing a bit much about a couple silvers, but they are rare in my area because things aren’t very old, and these are my first silvers found..
