I think it's spelled Tarsacci.
With an 'a'.

You are correct. Thanks

Bearing in mind how many detectorists can't spell 'Deus' correctly, it may have been unwise for the inventor to choose the name he did .... I can forsee Tarzachi, Tawasaki, etc appearing in the coming weeks.
But he could've called it the Gargovatronic GGT8000, if he wanted a retro 1970's feel to it. !

I did notice that a Google search ( months ago) for the name produced almost no hits, which may be intentional. Having a unique name will avoid 'false hits' about "Carlo Tarsacci Pizza restaurant" , "Tarsacci speedboats" "Giovanni Tarsacci fine leather jackets" etc etc.

Update: We've just had a Tarasacci mentioned

I am curious as to why they chose that particular name. It does seem like it is going to trip up a lot of detectorists...myself included. Lord knows I have heard enough people pronounce Deus as Deuce and even Equinox as the same as the beginning of Ecuador...the Eck-u-nox.

Even MDT 8000 will be hard for me to remember too...have too many names and numbers in my head from work. I've already been incorrectly calling it the MS-800 for some reason.

Just sounds like one of those Chinese detectors as they all start out as MD-####

DeepTech Vista X with 3 search coils.
Works for me

I di wonder about that MDT prefix myself. Is it Metal Detector Tarsacci, or something more complex, eg. the D is for Dimitar. You're right, though, if it was the MD-8000, I would expect the name to be already in use for a Chinese machine that finds objects 7 metres deep, yet only costs 45 Dollars.

Here in the U.K, Equinox IS pronounced "eck-wee-noks". Dunno why. Equal is pronounced "ee-kwull", , Equator is "ick-way-ter", Equatorial is "eck-wer-tor-ee-ull"

So, how about a nickname for this detector? Maybe one will materialize. May have to let purchasers use some, one might come to mind that fits.

Zak 8 will suffice.

Yeah, something like that -short
Will save time typing about it.

MDT = Multi Domain Technology

Domain:

Specified sphere of activity,knowledge,or territory.

Physics: A discrete region of magnetism in ferromagnetic material.

WOW and this is a Multi Domain detector---would one expect any less from NASA Tom?

Thanks for that, Tom. Maybe those Chinese MD-xxxx machines are multi-domain, too, hence why they have such great depth...

For the non-engineers out there, the "domains" in question will ( in my opinion ) be the "frequency domain" and the "time domain" , together. FD is regular VLF operation, TD is pulse-like. It's been suggested elsewhere it was likely to be a 'half-sine' based transmission. Whites and ML both have some patents on this method/variations thereof.

[ I'm still puzzled as to why the coil isn't exchangeable, though.]

Pimento,
Go back and read first entry by NASA Tom in original thread here.
He talks about coil.

Yes, that's what I'm talking about.
Hence all my speculation about the use of Hall Effect magnetic sensors in the coil, which would increase the likelyhood of no two coils being identical, and the machine needing to be calibrated to the individual coil's 'quirks'.

And notice NASA Tom says change electronics.
Does this “Change” mean - (adjusting) or more significant electronics changes/variations?

Pimento you may get another A grade here with your speculation.

One thing I wasn't sure about, re: coil swapping - are all the 11 x 9 coils exchangable/identical, or is it the change to a smaller or larger coil that's the technical hitch? If it's a case of every coil being unique and needing some 'calibration' , then there probably is some greater-than-normal complexity to the coil. If it's troublesome changing to a smaller/larger coil, then it's a bit more understandable. Some coil characteristics don't 'scale' nicely as you change size. So for example, you can make a smaller coil have exactly the same inductance as the stock size coil [ as is normal with VLF machines ] but it may end up with more inter-winding capacitance, changing it's self-resonant frequency and damping requirements when considered as a PI machine's coil.

There are ways round these problems. If the coil has a non-volatile memory built into it [sort of like a camera SD card etc] then it can be programmed with its unique calibration peculiarities. Then when connected to the detector, this info is read out, and the detector adjusts its operation accordingly.
Such techniques are used with computer hard disks, which have defects unique to each one, the electronics pcb has this defect info burnt into it's memory.
