Question on manicore

[woodbutcher]

I don’t have one any longer but for those of you that do I have a question. I watched a video of the manticore swinging over only iron, and it was grunting iron but the numbers stayed in the 70s, never left the 70s.. Which makes me think the audio and visual ID aren’t tied together..Can somone try a test if you have a minute and see..
My reasons for asking this question and watching a video is because I dug so much sweet sounding iron with high visual ID numbers..
Although the test video I watched had the manticore giving iron grunts when going over it, the iron was out of the ground in a test video, and iron always sounds like iron in test videos. When it's buried for 50+ years it will false a high tone..
I was rethinking the manticore and where I coulda went wrong with my settings,or understanding,, but after I saw the high visual ID numbers on the manticore in the test videos and the iron grunts at the same time, it just got me wondering about the visual ID and audio not being tied together

I don’t know about idea that the audio and visual ID are not tied together.
Etrac does not have iron bias settings like these newer SMF detectors. It’s discrimination settings are very granular however and like TNSS showed, those disc settings can be manipulated to make the scenarios shown in his video work well on surface and near surface targets.

Manticore can also have iron bias, disc and tone break settings adjusted to make those scenarios work as far as actual non ferrous targets responding as non-ferrous with “down the barrel” positioned nails barely falsing nearby. Again, I have only been able to get this to work on surface to shallow depth targets.

I truly believe that the audio is the foremost deciding factor, visual is just additional information and NOT a deciding factor. Out of the ground testing while useful can't emulate real condition detecting. Minelabs "fix" for iron falsing lies within their updates, which people are a reluctant to use for some unknown reason. Pre Industrial age home sites and newer are littered with iron of shapes and sizes not to mention the nails. Detector responses in this matrix regardless the machine are endless. Payline screen watchers are doomed for this reason. Use of the update settings will improve your results, don't afraid to use them aggressively if conditions warrant.

There's a few machines on the market, fisher etc where the audio and Visual ID are not tied together. I'm gonna say from what I saw in the video the manticore has separate audio and Visual that are not tied together either..Cant have a solid 70s reading over iron and a iron tone if they're tied together. What's more alarming is that the manticore in that video shows it reading solid 70s over iron . I'm not a engineer but it can't be a good thing

The CTX they were separate but worked together Randy Horton told me this he tested the CTX for minelab . sube

I was watching videos on the 3030 today on YouTube, I have a 3030...Anyhow,one video came up from Calabash, 3030 vs manticore,something about a Mike drop ? If you watch that video and go to 8.25 minutes into the video he showed the manticore over iron alone , I noticed the ID stayed at a solid 70s but the audio was iron grunts like it should be. I don't think he noticed it, but who knows

Iron Halo effect.
I don't know of any machine that won't false on it.

As iron leaches out into the ground it creates a like Crystal made of iron ions/iron oxides around the object which because it's larger than the object and a cross of minerals in the ground mixed with iron oxides.
It will most always give a high vdi.
Most often like copper or silver.

Breaking up the crystal matrix it will go back to iron grunt and vdi.

A hard stomp over the target can break it up.
Not always.
Though in iron infested areas I carry a 1/4" 12" long screwdriver I push into the ground near the target and give a firm wide wiggle.
This will most often break it up.

An example.
When you get those nice sweet signals that just completely disappear.
It's usually something like a bobby pin, small finishing nail, or thin piece of iron wire that has Completely dissolved/corroded into the surrounding ground.
And has created the iron halo.
When you dig you break that crystal matrix destroying the signal completely.
People to often call it a ghost signal.
It is not.

Digging in blonde sands notice the orangy brown coloring around iron targets.
That is the iron halo crystal matrix.

In the video I’m talking about the iron was on a board, not in the ground and the manticore was reading 70s on the ID .. I agree with the halo in ground though, but this wasn’t in ground

Still feel like I am in infancy with the manticore but I have to say the last few hunts before freeze up produced no ferrous fooling entering my pouch. Yes numbers in the 70’s over iron sometimes but not consistent. Turning slightly and working short arcs the 70’s turned to ferrous numbers. This along with higher tone breaking up and turning to all iron grunt. Everything in my pouch was copper, brass or mixed with iron(brass buttons with iron studs). A few times I thought I got fooled but once digging through the spoil pile and removing all the iron I would find the copper or brass object I swear had to be there.
Another thing I found is in heavy, heavy iron don’t be afraid to lower the sensitivity. Start by just lowering one number and trying it until the high tones/blips break up more and machine is just perceivably quieter and more stable. At one site I was getting overwhelmed with low grunts mixed with high tones and rechecking signals. I lowered sensitivity from 22 to 18 over the period of about 30 minutes and it made a big difference. I think the manticore runs so hot that just minor sensitivity adjustments can produce good results without given up anything in the depth department. After all….if you can’t hear a good target in the “shotgun” mix of signals what good is an extra 1/2” of depth?

The videos I saw that showed the Manticore screen it was mostly giving negative 70s (red line under the numbers) over the nickel and gold ring and negative 50s to low 60s swinging over the nails and silver coins. That is what I have experienced too on shallower ferrous close to these coins. Deeper iron can false more.
