Alright.
I am in no hurry.
Definitely some unorthodox use/ops using Manticore.

Video, comparing ATLC and Goldfield using M8 coil - sweeping nickel on edge the hard way.

Throughout the past 24-hours....... I have managed to watch Video's 1, 2, 3 & 4.

Probably the best approach that I can communicate........ is to clarify to the viewers ...what David/TNSS is demonstrating:

Iron ID's as: IRON

Iron + coin (whether a Zinc Cent, Nickel, Dime or Quarter)....... STILL ID's as: IRON.
BUT.......... even though any combination still ID's as IRON. , . , . , . , . , herein lies the difference:
Even though a coin next to iron: ID's as 'IRON'....... the Manticore ID's the combination (coin + nail) in a DIFFERENT region on the iron scale.
David (via a custom program) is highlighting the IRON + COIN combination.....and allowing it to audibly report...........,,,,,,,,,,,,,,,.................. and audibly nulling JUST (iron only) the simple/stand-alone IRON.

There are SOME drawbacks; (((yet, still plausible))):
1. 3D depth differences BETWEEN coin & nail(s)
2. Coil approach angle
3. Deep depths..... causing some falsing
4. Two BENT nails (in a variety of orientations) next to a non-ferrous target
5. Mineralization ID skew
6. Two (or more) entirely different types of nails (eg = modern round-nails + heavily oxidized, older square-nails)
....... and a list of other variables.
BUT....... all is NOT lost! A experienced user.....with some skillset......can overcome these variables.

And this is EXACTLY "WHY" these engineering controls have been installed/given on Manticore. When you feel you have 'mastered' Manticore...... and are getting bored. , . , . , . , . , you can delve into a whole new World of advanced/custom settings & configurations.

Some good data Tom.
I’ll just throw this in here. I wonder if screen was bigger so the detector behavior trace wise could stretched out more in the vertical - would this indeed give user more accurate info?

I will close this out with the following.
Users of Manticore running it more traditionally.
I’ll use this example.
Let’s say you are in a sports field using ATLC and signals are sparse. Even iron tone signals are sparse as user is running detector with horseshoe on. It might behoove a user to when they do get wholesome iron tone signal to glance at screen. Iron IDing say 50-62 approx and trace it seems to run against the wall on top of ferrous limits —- user may decide to turn on such situations and resweep.

Knowing what I know now about Manticore. Would I ever hunt a sports field using detector with traditional setup and be running horseshoe off? NEVER!!

Could iron or nail be your best friend depending. Hmm

Have a few questions for Tom and other seasoned users of the M-core. I'm still learning about this detector and have not been out much with it. I noticed today while playing with the settings inside my house the following; In goldfield mode I'm not sure if I can change the ferrous volume and the tone of ferrous, to an iron grunt. I'm sure I saw an adjustment for ferrous volume when I was in prospect audio, goldfield mode.
Another thing I don't get is in ATHC or LC, in enhanced and or in normal audio if I run my upper ferrous limits at 0 and I run a rusty 6 penny size nail over coil I'm getting what ever my tone is set at for where this nail comes in at. Low 50s in LC and mid 70s in HC mode. I thought the numbers would at least turn red on the screen. Horseshoe on or off, doesn't matter. I can not change the ferrous tone in volume or tone to get an iron grunt. I have the tone set on 1 and tone volume on 1. Its almost like when you shut off upper ferrous limits to 0 you are killing your volume and tonal ability for ferrous tones. Once I reset the upper ferrous limits to the default position, then I can vary my ferrous tone volume and the tonal ability of it. Why is this? Thanks guys for any replies /help. Steve

I’ve been running the manticore for about 6 months now, and it pulls the good stuff out of iron and trash very well. My question is, has anyone ever noticed that the display screen has a bright flash of light on the edges or border that kinda looks like a camera flash or lightning. It seems to have no effect on how the machine runs. Also no consistency on when it is going to happen. When it starts flashing it seems to last as long as I keep hunting. Thanks for your help.

Steve....... I'm short on time........BUT....... let me say (start with) this:

Let's say you have Ferrous Limits - Upper on: 4. You will see a grayed out portion .... on the Upper part of the 2D graph. Any target that falls within the Upper (within the grayed out area) part of the 2D screen...... will ID with a low/iron tone (((as long as it is not Notched out....... and ..... as long as you have sufficient Volume for the iron tone))). Any target that falls onto the 2D ID X-Y screen.....that is NOT in a grayed out region.......(((in other words: falls anywhere on the clear/white part of the X-Y 2D graph))) will give a non-ferrous tone....congruent with it's non-ferrous conductivity.

IF you place your Ferrous Limits - Upper on: 0.............. there is NO grayed out area on the 2D screen. ALL targets...... including iron....... will now fall on a clear/white part of the X-Y 2D screen............. and the Manticore will report it as a non-ferrous tone!!! If it is a highly conductive ferrous implement/target...... you'll receive a high tone. If it is a medium conductive ferrous target........ it'll produce a medium tone!

For starters...... does this help any? ((( I may not be speaking clear enough!!! ))).

[[[ Lightning flashes on ANY part of your 2D screen........ is NOT good!!! ]]]

Thank you Tom, Yes that makes sense now how you put it . Either a grayed in area or clear area. Depends how much iron descrim I dial in and where the target falls. I assume the bigger the iron or nails the higher up the scale the ID will read and would think the higher the pitch of the tone. I will practice more this week so as to feel more comfortable with what the detector is saying and doing.
Why I was experimenting with turning off the iron limits is I'm trying to determine if I really need this filter on when hunting. I'm trying to squeeze every bit of depth out of the M-core. I mostly hunt the woods here and do not come upon iron very often. Not much junk either. And occasionally a shot shell hull, bullet, or cartridge casing that I might dig up. Looking for mostly high conductive copper with occasional fur trade items, brass. My thought would be to run the detector in goldfield mode with prospecting audio at a 3 recovery speed in multi -frequency. Or Tom, do you think that ATHC w/ prospecting audio or possibly another audio mode would give me the edge in the woods for deep detecting. If I understand right, when in goldfield mode, I can not alter the tone whether be the non- ferrous or the iron tone? Thank you, Steve

PS. Can the goldfield mode be deeper than ATHC in sterile, medium to moderate mineralization ground?
