Anyone that know about this detector?

Turkish, not bad. But...heavy weight! You must be very strong man to hold it for more than 5 minutes on the field....so as i heard!

I think the value of 1.25 amps is a bit generous, as we cannot consider a 100% depletion of the battery.
Something between 60 to 80% of this value , depending of circuit ,or between .75 to 1A. That is a lot anyway.
regards,
Fred.

In reality draining 1.25A from a 5Ah battery for 4 hours will not completely deplete it. I think there will still be about 1V per cell. i.e. for a 12V battery, it should still measure as 8V.

Hi Qiaozhi,
I assumed this is lead-acid sealed battery, with 6 cells.I think they´ll drop quickly when you drain what i think is around 60 to 80% of its capacity.

Dear Mickael,

Can't you contact previous owner of this MDL8500 and ask him where he have purchased it?
I'm realy interesting in this device!

Best regards from France

Hi, this is what we tried frequently, unfortunately they told nothing about it, it seems they want this be exclusive to them.
but as I know one of them has a brother in USA who is a top engineer,he made arrangement and sent this device for them some years ago and their brother was fraternized with one US military or army officer. the officer prepared this device for him. it is without any manual although doesn't need, operating is so much easy, more easy than hobbies like "Whites' XLT".
but I think after our success in THing and with a good offer (about 50000$ for every unit) can arouse them to make connection with their agent in USA. I pray god save their agent remain alive by that time.

Michael,

Can you extract scheme from your MDL?

Hi, unfortunately no Berti, at first I had such decision and even get other help for this, all disappointed me.
Regardless of ICs cleaned surface, the white chamber part which is very important is sealed and inaccessible and very risky try to open it up. if dare to open it, what can do with programmed microchip?
like what are inside Minelab devices, even though being manufactured and replaceable, who have made a working one?
After that what about ICs???!!!!! no way man. at first I tried do this and took it to my friend, he bewared and disappointed me entirely. the solution is only find maker.
We don’t know how many of this device have been produced and in users hands, I’m so much glad god esteemed me put it in my hands. I want all find a way to access it and me to a spare. other kind of detectors (of course in remote areas) are nothing in comparison with MDL.
Otherwise in indoor places is unworkable cos acts very unstably for existing metals and various fields around.

Did you see this posted in the Coils Forum?

Looks spookily similar.

Hi, so what Qiaozhi? what do you exact mean? are you meaning that can make something like MDL with these stuffs?
or want to tell other thing? as I know there are many of these exaggerator sites to sell some circuits,... for making aaaa let us say a good MD.
Qiaozhi have you ever made one device based on their services?
or any body else has done? how about results??
if I remember right one was PD3200 that was in internet for a while, i don't knoe can find now or not.
If all things be right, the result is eventually like my first PI(which put a concern link in previous page) nothing more although not even like that.
or supposedly result be best and becomes like Lorenze products, not better, hum? all suffer of drifting,... stop... retune.... stop..
retune... oh, god, boring devices.
I'm telling Lorenze has no word for telling in comparison with MDL.
What I wrote here all are based on 100% field tests in wild ground-terrain conditions not in vitro; a 100% genuine report.
of course I didn't get your main purpose of introducing this site, anyway thank you man for link

If I'm right you live in USA, yes? if so, please do your best and mobilize your potentialities, friends,... to find its' maker. I assure you, won't be remorseful.

Oh, one question that always comes in my mind: Why famous MD produsers like " tb elect, Fisher, Whites', Garrett,.." with those dozens of engineer teams don't make such feat detector? after passing years they are at the same spot, without noticeable progress( be marking time).
or no they have capability but have been banned to produce such feat detector? they only got permission to produce some things
just to entertain some interesting people nothing more. and people are unaware of the fact that the technology is highly ahead of
what they imagine and have in their hands.
I have heard that UNESCO is one of the predominant preventives.

The problem is not at UNESCO... they have to protect heritage etc... so it's their work, their main purpose... but have nothing to do with THing or MDs... it's something they made everywhere and everytime... with anyone who wanna hear that stuff and give political answers to particular, regional issues.

Do you really belive UN have time to play with MDs at now ???

No, no... I tell you who are those smart people that let THs belive what they have in hands is today's technology... where actually is 30years old and more stuff... just with renewed components and look about housings... coils etc etc

They are the BIG manifacturers: they don't need to push technology ahead or promote new class of MDs cause they get already what they want: MONEY

I think there's unwritten agreement that nobody of these will push too far new technology in the MD industry for TH. That's all. Business.

Sure they are ready to make such improvements in military and other equipments but not THs... but not as heritage preservation feelings they already filled the world with millions of MDs ... it's just MONEY the word they like.

So... forget about UNESCO stuff... and blame the well known toy-makers...if needed.

Kind regards,
Max

Hi, about UN, maybe you're right although I'm still suspicious, cos have heard this about UNESCO from some different men even one was a member of my country cultural heritage organization who told this and even more he told me that UNESCO have made arrangement some unique detectors be only available for governments and not be produced everywhere.
about businessmen who only think about money you are absolutely right.

[Berti]

re

You must be right Michael.
All governments have secret professional team.

Nothing mysterious. It was just that these two devices seem to have some similarities. They both have cases that look slightly similar, and are (supposedly) both microprocessor controlled. I was wondering whether your detector was based on one of these. Remember that these detectors are sold as kits, so it could be possible. Just because it says "made in the U.S.A" on the white box, does not mean that the design didn't come from somewhere else. The label only means that it was constructed in America. It was probably a wild stab in the dark ... but who knows?

Hi, no Qiaozhi, they never looks like similar neither in appearance nor inside components.
I have seen and know many of these kinds. an unfair comparison.
in the link you referred, see 2 control pot(like many other PIs including my first PI) but in MDL device is being controlled all by push-buttons, and we never use it to increase signal power or correcting drift, reversely, occasionally use it only to omit some interfering noise or signals coming from somewhere to equilibrate signal.
with pushing one key(that suffices for searching hectares) it becomes silent(of course with single pulse ding at every 3 or 4 second be heard in headphone). no need to stop for balancing, through walking can do it without any problem.
I know those assembled one, non of them can do such.
Assume be so and MDL is made of such places, it's really a feat. if so, possibly more easy to find maker.

as another side inside MDL you don't see plenty of such ICs and Caps, outside the white chamber we see only one horizontal IC and 3 perpendicular 3 pin IC similar to LM317(surely one is a kind of regulator) and the arrow with "High Voltage" inside points to biggest of these 3 pins(possibly is a convertor or amp). and maybe is an IC or microchip inside the white chamber.
I know some PI detectors which in appearance are similar to MDL such as: "SSP..." series made by accuratelocators or "DTI- Genesis", but in efficiency are so much far behind MDL. they have some jingle-jangle options in program and a beautiful LCD without satisfying result. all are boring. in MDL never see such things, very simple all metal detector without any discrimination, a small simple LCD, but very powerful and highly stable.

Just because it says "made in the U.S.A" on the white box, does not mean that the design didn't come from somewhere else. The label only means that it was constructed in America. It was probably a wild stab in the dark ... but who knows?

and also on back of board you see "CALIBRATED AT 2002-USA" as you see in previous page. no matter made in where, matter is really worth.
