I took the two coils out to the garden to see how they performed on depth and emi. video: https://youtu.be/ckK2S6rUhDw

I'm still in awe of you and anybody else being able to hear targets at 8-10 inches deep.

Why are you not hearing coins at 8-10 inches deep? You should be able to with the Deus.

It would be interesting to have a bit of a mineralized spot in your test garden.

You could probably use some iron grindings etc.

The idea is to replicate how the ID changes on the minelabs in this condition but the Deus will still sound better. (Or does it?)

See with the minelabs, that first number goes from 12 or 14 on a coin sized object right down to 25 or more, depending on where you have that black bar set. You may also find the second number may also move, instead of say 42 on a high conductive coin, you may see it go left into the 30's.

It takes a surprising amount of effort to dig some of the deeper silver with the minelab at mineralized sites. I'm positive people are walking over a lot of deep silver because it sounds like garbage, bounces around.

If a coin says 12-42 in an air test, it won't say 12-42 in a mineralized site, it will bounce around numbers each swing like like 18-35 then 22-34 then 16-40 then 21-37 and so on. Boopidy bop boop.

Older silver like this coin and decomposed iron go hand in hand at my particular sites.

In certain light, you can see some rust tinge on this coin, I have other coins with a lot of rust stuck to them. I think the rust bonds with the silver oxide on some coins if it's thick enough.
Anyhow it's not that all silver comes out rusty, just an indicator of how saturated the ground can be.

Now I'm talking about mineralization caused by man, I can walk 30 feet away and the ground may be much milder.

Anyhow, no pressure, if you get to it one day great, if not, I won't be put out.

Hey CD. I'm really anxious to see how stable the higher frequencies are where theres a lot of iron. I tend to favor the 12 and 18 frequencies on the lo fz coil because they seem to handle emi better and because I'm a nickle freak. But I wont hesitate to go to 8 if small iron flakes too bad. Its hard to believe the elliptical could be even quiteur than the round. Correct me if I'm wrong but it looks like the round offers a bit more coverage while the elliptical may be a tad quiter plus offer a bit more separation. thanks.

I like the nine, but there will be a 5 x 9.5 too. Im just used to the shape of the nine and that might be why I like it better. I ran the nine today in 28 kh and it smacked low conducters.
