I'm not sure if I understand how the Manticore 2D display is supposed to be interpreted - what exactly does the vertical scale represent, for instance?  Could someone point me out to a clear explanation?

steveg has posted a bunch in another thread.  Here's what I think was his first on the subject where he explains how the Minelab FBS detectors give target information with two 'coordinates'.  You may want to browse on down and see what else he and others have to say.  IMO ML's explanation so far has been a bit vague, and as I might have said in that thread, seems like they may be afraid of making things sound too complicated so the use simple explanations.  But the manual hopefully will go into detail.

It looks to be simular to the ctx...vertical (y axis) is ferrous and non ferrous...high and low stuff is in the ferrous ranges..if your in the mid zones your looking like non ferrous. The horizontal (x axis) is going to be the conductivity line....stuff on the left side less conductive...stuff on the right side more conductive. Small piece of aluminum on the left side  half dollar on the right side...  At least that’s how I’m seeing it in the videos. 

When I hunt with the ctx I’m always looking at the screen. When using combined mode in ferrous coin bottle caps will be at the top of the screen while most nails and larger iron will be at the bottom of the screen...good stuff in the middle...I usually toggle back and forth from the disk screen to wide open as you loose some power when in the disk screen. Findmall was a great resource for learning the CTX. You could down load others programs that were already proven.

What's the difference between high and low then, I wonder?

I would think the type and amount of  ferrous...in the target but this is speculation on my part...

Yep, spot on...

Yep, basically...

As I understand it, stuff like rusted nails, etc. will be up top (I think), and big iron, like horseshoes, axe heads, etc., will be down low (I think).

I looked at CTX3030 manual trying to figure out what the 2D detecting screen shows, and I'm still not sure what the vertical scale 'ferrous characteristics' actually show.  It seems that its values increase from top to bottom (with the horizontal conductivity scale going traditionally from left to right).  So the way I understand it non-ferrous targets should show on top of the screen with the horizonal courser position showing the increasing conductivity (size in a way) from left to right.  Is that correct?

Is this convention the same in Manticore?  i.e. does the vertical scale have the same meaning, with the increasing ferrous component from top to bottom?  Somehow I was under the impression that in the Manticore screen the non-ferrous targets would display along the middle line, with those showing ferrous characteristics departing from it up and down, but I'm not sure if this is true.

He's blanking the iron out pretty good in this teasuretalk,

https://www.minelab.com/anzea/community/treasure-talk/ctx-3030-threshold-blanking

For me most iron is in that bottom right corner that is blocked out, and the very top right corner is the wrap around iron.  The CTX discrimination is awesome, it does loose some depth the more discrimination you use but with it's deadly accurate ID's you an eliminate targets you don't want easily, and with the high resolution target information you can block out each of those tiny little squares individually to remove targets.

Your going to have to ask the engineers how they can make ferrous top and bottom and non ferrous in the middle. I’m thinking the principal is the same between the ctx and the manticore as that is the way I have been seeing in in the glances I've had at the videos. Your thinking that something in the middle would have a medium ferrous content right? One thing to remember is that there are many forms of iron alloys and the engineers have had to get very creative so as to help us not dig crap all the time. 

On a side note it seemed lots of people loved their etrac and never went on to the ctx presumably due to the price? This manticore is going to be a fine machine as long as it don’t leak...and it makes you wonder what they have going on to replace the ctx? The fun never ends.

I have only been reading about the new Manticore & don't have any Minelab background.  I was understanding that the 2 different sections for Ferrous on the 2D screen was to classify small iron from large iron.  Nails vs axe heads or rotten tin for example. Tom D mentioned 99 points of Ferrous range & 99 points for Non Ferrous.  The Ferrous range may be split at some point,  < to one line, > to the other line. The entire Ferrous range would not have to give a TID, just the smaller stuff close to Zero. He made the point that Archeologists/Relic hunters would really benefit from the new tech in the Manticore.
