Manticore In Iron (nail Beds)

...I simply asked the question why is not iron falsing in your test then when the nails out of the ground?

Can't it really only be 2 things, or likely a combination of both? Depth (all VLF discrim loses accuracy with depth doesn't it?), and ground mineralization?

Depth is easy enough for him to test. Just do the same test he already did except raise the coil up in 1-2" increments at a time to see if it eventually causes falsing alone.

If it doesn't, then it's probably ground mineralization either alone, or in combination with depth. Iron, unlike gold - makes a pretty clear and visible halo (this just iron leaching) since iron readily oxidizes. If it's just ground+depth, a rebury test would tell that. If it's something to do with the halo, then ground+depth tests won't necessarily show it and it'd be harder to test, but you can accelerate oxidation/leeching via chemicals and maybe electricity, and make a buried nail have an in situ halo for testing purposes, like in an acrylic box so you can see it and prove it's there.

The in-ground falsing does sound like a problem but I can't test the various solutions without a Manticore.  I'm don't think there are iron loaded sites I've visited around here that would be a problem anyway.  I've read that NASA-Tom is already testing an advanced version of the Manticore software so there could already be fix to mitigate much of it anyway.

Sounds like a normal Christmas to me.  We did the same in the morning after breakfast.  The dog made out like a bandit!!  Then watched all our planned Christmas movies and now I'm on to Alien (ET) documentaries.

I recall Tom saying his version was '59' at one point. I believe the shipped version is '50'. I don't believe he has easy access to the proper sites for 'bed of nail' testing, maybe other 'testers' are running newer versions of the software also... I have a site with a lot of small gauge rusty wire bits everywhere that I'll try out in March/April when we thaw out here....

I'll hit heavy irons with mine shortly after it arrives.  I just wish the M8 coil was arriving at the same time.  And wish I knew how long it will be for the other coils to surface.  I'll get them both, but I really, really want that smaller 5.5x8.

Given I'll be stuck with the 11" for likely a good while on the MC, my 800 with the 6" is coming along too...

In a video that was recently posted about comparing in the ground signals between the D2 and Manti, Jimmy was given the suggestion to lower the sensitivity to stop the iron falsing. He reduced it 50% but the Manti still showed silver on 4 iron targets that the D2 correctly showed as iron. According to the D2 guy (Carson?), the site doesn't even have much ferrous trash.

I don't think it's a big deal though. All detectors have bugs that need to be worked out. I'm sure Minelab will soon release an update to address this issue.

Forget CD video on nails, have a look at Brass Medic's latest video. I think it is very good and targets are investigated as most of us like to investigate them. Being a long term nox user the Iron seems pretty clear to me as being iron.

Yes totally, I think its being played out to get more views. Brass Medic's video I found very professional and he certainly knows what he is doing.
