Real Metal Detectors

Possibly....
look this link;
http://www.enkaymachine.com/proceq4.htm

a friend came to me with so good impressions about this one. It is not what we want here, but he tested it and was pretty amazed with performances.
He claims detection of small iron box 20x10cm at 1.3 meters in soil with this device....!? Is it possible?


"Intel inside" sticker on that device is nothing but local joke, i presume. Some joker put it there...

Hi,
maybe is possible using a large coil with it... seems made for concrete stuff... if it works in concrete I think will work also on soil.

Detection range is not so much using a large coil... so, yes, I think it's possible.

Kind regards,
Max

Looks like there are a bunch of tiny letters we can not clearly see!! Look at what I circled below. Everything is needed when you investigate, like CSI on TV never uses fuzzy evidence photos . They would be out of a job.Do not be afraid to take it apart.........take care .......Happy 4th...............Eugene

Hi,
the first one series is easy... it's just "metal detector"... so not much of help...

Maybe the lower is some serial number...


Kind regards,

Hi,
unfortunately there isn't any other info outside or inside the box.
Max, clever man, yes you're right. the below circled by Amtech is serial number the exact written is: S/N: 81 MD6209 I had never noticed that carefully.
another thing that you see on pics is two attention label about not using any other MD near this device.

Oh, our MDL can detect easily a sheet 20 Cm x 10 Cm entirely buried at 2 meters depth. of course nearly impossible for other MDs;
it can hit precious metals(not-magnetizable) similar to iron!!!!. gold, silver, iron are somehow same for it.
I think I said somewhere here that we hit a quarter of horse-shoe at about 120Cm depth. the more old buried target, the more sensitive to it. it's killer of old buried targets can detect those from long distances.
about Intel inside, I don't know, but one thing is absolutely right that all of its’ working is microprocessor controlled, an amazing thing is that doesn't differ if you set the coil(2m x 2m frame) directly on the ground or hold it at waist level or 2 meters above ground, it entirely automatically tunes itself with ground surface and you never have signal falling or depth decrease. all the time you have ground balance and for this reason you can run with that, when you cross the line of target signal immediately nails it. unbelievable? it's not fiction all is right I swear god is right.
then look for maker please.

Hi Michael,
It looks dificult to find any info about it.
Instead of brand, i thought MDL could mean "model" , but this didn´t help to find info about it.
Maybe if you could take more and better pictures of inside, some special component could be identified .
In any case it would be interesting to see it better, and what is there below the white plate.
Is there any cooling fan or holes? If there is a Celeron CPU cooling will be needed.
Could you tell what voltage rating is the big electrolytic capacitor?
As Qiaozhi says, it looks like a high voltage PI.
Regards,
Fred.

Hi Fred, yes, you're right MDL 8500 is the model. Of course when turn it on at first it introduces the version I think something like "ver.1.1.8" or "ver. 1.2.8" . it takes 5 minutes (operator should wait this time to be passed) and after that device will be loaded and ready for work. it's highly possible they have made advanced models with best discrimination.
one serious question that brought in mind from first is; why makers worked such anonymously?!!!! Don't they want money?
what a reversed world, When a device is the best you can never find it easily.
unfortunately the white part is hardly sealed as I'm afraid of defecting can't dare do anything on that.
about fan, it doesn't seem exist as there is no air way orifice anywhere on outer box.
I've seen all other parts, no name.
the big capacitor is 10000 uf-105V.
one other thing: for turning device on is necessary in addition to power cable, the search coil be connected.

Hi Michael,
Thanks for answer, yes it is strange that that this device is no more advertised.
We could try to understand on what principles it works,but it seems dificult to find the maker...
It really looks like a high power PI with advanced signal recognition system,any parts value could help determine its principles.The big transistor or 8pins IC values could help,if you have a chance please tell us any semiconductor value you can find, it´s not much but all we can have .

Good luck with it,
Regards,
Fred.

SSP 3000

What about these devices? Are their claims true?

http://www.accuratelocators.com/ssp3000.html

Anyone have heard about it or use it?

Michael as we think MDL 8500 has no information and we can't find it what do you think which is in the second position?

[michael]

Hi, I don't know much about SSp series, but have heard some good things about. can I express any opinion about what have not used or seen?
I know "Lorenz Deepmax" is very good. of course with bigger frames.

[Berti]

Says:The Original & Still The Best!

Michael about Lorenz deepmax you thought that will be better to buy this or to search for another one?


For this they say: The Original & Still The Best!

Guys from America should know more for this above.

PCB

Hi, you're right, but as another side we've seen some entire US-military stuffs with only "Made in U.S.A" and a code number on it, nothing more, even without any name, but an excellent object made of excellent materials with best work on of them was a binocular night vision with indefinable quality that advanced Russian ones was hobby in comparison with.

About MDL : We know definitely the origin is America and had been sent from there. why the owner sold it?
A: cos he used to search with 1m x 1m frame whereas with 2m x 2m is the best attitude and the most stable.
as MDL has no discrimination and the owner and his partners were tired of digging for many of junk metals at great depths so set him thinking to buy a "Lorenz deepmax" only for discrimination and sell his MDL.

All the things we know is what you see here in Pics. it seems the main microchip is sealed in white part is entirely packed and inaccessible. in the arrow has written "high voltage". Datas on all ICs has been erased or abraded.
only on this white part you see "Made in U.S.A"
It's obvious isn't a homemade device it's an awesome neat work of a team work.
again I emphasize; It really worthies, it's a treasure by its own. use all of your communication potentialities, friends or anything else
to find the maker and please do a great favor, inform me. it will be so much appreciated.
oh, one thing now sparkled in my mind: as you see there is a label "Intel Inside celeron".
maybe Intel will tell the firm or guy who orders espesific microchip to Intel? or no, it never divulges?

hi michael,

did you check the both sides of the PCB, you may find the manufacturer name printed?

regards,

[Max]

Hi,
the "intel inside celeron" sticker means nothing from itself... anybody get one from an e.g. old PC and put there...

but also, if it was put there by manifacturer, could also mean there's something intel processor inside for real.

I mean, celeron would stay for low-end processor of any kind...

For example... I don't know if some Xscale Intel processors are branded like "celeron" too when low-end. The Xscale ones are used in devices like Palm PDAs, tungsten serie.

Anyway I have serious dubts that an Intel celeron something is inside it... probably is just a joke with sticker. Sure there's something mcu, but common stuff in PIs... like some AVR or PIC.

Kind regards,
Max

Hi, I looked all parts carefully(except to the white chamber where is inaccessible) no name, no name. only at back of pcb (exact is opposite side of white chamber) has been written " CALLIBRATED AT 2002-USA" as you see in Pic.
Max, maybe you're right about "Intel" label, but I don't see any reason for this joke.
for what? to deceive or cheat? no, no, at all. it works as the best, at first view every professional THers ( not naive beginner or newcomer) who has worked with all kind of detectors will be attracted to it.
then, if you were the maker, would you see any necessary to stick such label?!!
I never know the exact fact.
maybe common stuffs in PIs, but why is not same all other PIs? it's unique.
oh, BTW; I saw the big Cap carefully, I think is not 105V, at the back side of board somewhere I saw 25V all exact writes on it are:
" Rubycon 10000uf(M) 25V +105 C VXP "
Again, please do your best; mobilize all of your potentialities to find makers.

Hi,
as I explained exist possibility the Intel processor is really inside the box...but not sure a common "Celeron" as we can intend at first... like some economic pentium or similar... no. I mean it could be an Xscale processor or similar stuff... but branded as "celeron" cause Intel uses that prefix for anything that's not on top line about processor speed... you know... it's like another smart marketing issue there at Intel.

Could be something Intel made for cell-phones or PDA arena... I mean like an ARM-kind processor like the ones you could find in a Palm Tungsten.

These processors made by Intel are small, low powered and , much important, don't require fans for cooling... so could suit there, assuming the label is there for a good reason.

Now the problem is really hard cause device has no brand , as can I see.

What about the red logo on top right corner, can you enlarge or give a close-up of it ?

PS: about capacitor... there's sure a reason for it... so large... and the probable reason is... (I hope I don't disclose anything sensitive to someone here ) it stores a particular charge. The PulseStar maker wrote about this stuff some years ago... though the idea is old...now I don't remember exactly where but I read it and there's a way to improve S/N by using that method, that require a large storage capacitor.
The stuff works like this... the electronics charge capacitor to a fixed level, so you know how many charges are in... then the mosfet make it discharge over coil. This is a bit different from switching the coil from supply rail...and it's somehow the preferred strategy of top depth PIs cause of improved stability you gain this way... you know... in a common PI the battery discharge... and that slow drop could interfere bad way with S/N... then there are also other issues but too long to explain now.

I will search for informations about it ... but see it hard to get something at now.

Kind regards,
Max

Hi,

I though all PI´s had a big capacitor to supply the very hight impulse current.
I didn´t notice the red logo before.?? interesting.

Michael, did you try to hold one or other or both buttons while powering on the detector?
sometimes software information or setup appears this way.but proceed with caution...

Fred.
