New Detector; "Nokta" DPR!!!!

[michael]

Hi all.
Today I saw a new detector which even Kellyco is selling it. the name is "Nokta" and they've called it's mechanism DPR( Deep Processor Radar) it seems have both audible signal and visual type and made in Turkey.
somewhere pointed it's an electromagnetic detector. what do you guess about?
Can be a good visual metal detector or no, it’s almost certainly similar to OKM products a field detector nothing else?
Has anybody ever used this device?

Looks like gradiometer (or magnetometer) and PI detector in one unit - integrated. It is not new idea. I think i already saw something simillar in the past. It is not just simple field detector. I made EPE gradiometer. Experimenting with it in direct mode (bar meter on LCD screen) i noticed excellent sensitivity directly on ferromagnetic metals - so it could be used as conventional metal detector. But with huge drawback - it detects only ferromagnetics. In gradiometer mode it is measuring gradients in earth magnetic field. So...this Nokta is more likelly simillar, hybrid device. In that case it is workable and useable, not bogus. I see, there is pretty nice software, much better designed than on most of simillar devices i seen so far. And yes; it reminds on OKM software...
But..very important question is; how burried precious metalls (or deposits) do affects earth magnetic field? Are there any noticeable variations in gradients on soil surface? Could it be used in accurate locating of precious (coloured) metalls in soil, at all?
With my EPE i alredy had excellent results in locating small ferromagnetic items in soil at very high depths. But no results at all on coloured metals like Au,Ag,Cu,Al.....
So main question remains the same; does...and how burried non magnetic metals affect earth magnetic field and are there any significant changes in emf gradients on soil surface?

Hi,
the magnetic field variation you can get with large deposits for sure... but then you have to survey a large area... take hundreds or thousands of readings and elaborate data off-line... creating like a map of field gradient vs position... then you can guess if anomaly is due to the deposit or not.

I think it works for large deposits and same for oil big reservoirs too... cause magnetic properties are different from soil near e.g. gold ore/native etc

But you need large amount for obtain small reading on such devices...

I think also that common, fluxgate, magnetometers/gradiometers are not good for that stuff... you need very fast reading... like in this stuff...

The P3-Orion has one in the tail (look at picture... the yellow tip in the rear is the sensor housing)... as I remember... anyone could confirm that ?

The Orion uses that fast reading mag to scan sea for submarines (made by titanium alloy mostly) due anomaly... but... as someone said... can detect other stuff...

I think some retired USAF/U.S.NAVY could confirm that.

You need something similar... but maybe a plane is required to take sample readings.

Sure all that stuff do not apply to small non-ferrous target stuff... I think it's impossible for a mag detecting e.g. a gold coin buried, deviation of gradient is too small.

Kind regards,
Max

Hi,
thank you Peroon for your attention and useful comments.
If it's as you describe, can be a workable device.

...very important question is; how burried precious metalls (or deposits) do affects earth magnetic field? Are there any noticeable variations in gradients on soil surface? Could it be used in accurate locating of precious (coloured) metalls in soil, at all?

This is obvious, for fresh buried nothing, but for very old or ancient buried, is very noticeable.
this 's been demonstrated to me with various type of tests I made personally with expense of dedicating a lot of time and money.
of course the time of these treasures goes back to thousands years ago. If you were here would definitely feel the formed field/halo with detectors and would become astonished. also my PD reacts clearly near and over the locations.

As I've put before we have one unique PI (MDL) that's very powerful and we found 3 treasure locations, it was incredible but we got first signal of the biggest one from about 90-100 meters.
all targets are at great depths; 12 to 16-17 meters. others' signals appeared from 30 to 50 meters.
now we're busy to dig up the smallest one, by this moment we're at 890 Cm depth, should continue up to 12m and afterward burrow 2-3m, cos we made a mistake and didn't calculate and correct the slope of ground.
when we succeed, will put here some pictures of treasure.
MDL is an ideal PI, but has few disadvantages: can't find out exact depth and metal kind anyway visual information among with audible like what Nokta claims is much more better and easier; if this detector can penetrate deeply is an appropriate complementary for our MDL.

With my EPE i alredy had excellent results in locating small ferromagnetic items in soil at very high depths. But no results at all on coloured metals like Au,Ag,Cu,Al.....

Is it possible to put it's picture and a report of found objects and depths?

Hi Max, thank you, in our world everything is possible it can be highly possible that US army has such technologies be able to even detect buried treasures.
In Nokta video demo you see it detects a big gold coin from 60cm in air, of course not sure it's really a high alloy gold not an iron yellow colored or other tricks......

I don't know this detector, but the lack of technical details and the high price sends out a message of "buyer beware".

There are also other warning signs. For example, just look at the features list, where the first item is "7 inch TFT screen" and the second item states that the search coil is made of strong impact ABS plastic. The list goes on like this without providing any useful information. The whole advertisement looks suspicious to me. I suppose you're meant to be so wowed by the interface, and how much RAM the system contains, that you'll part with your hard-earned money. The claim of 10m detection depth is a sure giveaway.

My advice would be "try before you buy".

Does anyone notice anything fishy about the demonstrations?

new subject?

I never seen any night hunter using Nokta products in Turkey. Consider their claims like LRLs. Also I see now why kt315 kicked from Russian MD forums.

"...Is it possible to put it's picture and a report of found objects and depths?.."


No need for that actually. I reffered that on my testing field with items burried in soil from 50cm up to 3m depths. For example; iron piece 12x6cm at 90cm in soil (4 years), EPE in bar mode detects with 80% bars on LCD, which is excellent sensitivity comparing to conventional metal detectors.
And so is with other ferromagnetic objects. I could perform more tests and form table of depths, but that will not mean much for subject here.
I still can not upload files and photos?

What? Tell us on what should we pay attention.
Of course; not knowing details, everything can be suspected. Video doesnt prove a thing, of course. I dont know any details on this. Demonstration as well as all other information on this are very sketchy. I agree with Qiaozhi, customer must pay attention and check this before buy.
But lack of details doesn't mean it is bogus by rule. I am not saying it is true, either. Just am interested to see what is all about.

Well...this is very true. I experienced that exactly with EPE. Very good and sensitive on ferromagnetics but also doesnt react at all on coloured metals...(items and medium masses, but dont have conditions to check on large deposits burried long time ago).

I keep your money. in Turkey. it is why I was kicked in Russia. there are many forums and BELIEVE me I give ONLY one answer on Nokta dream box. you know WHAT.

You're a bad one... KT, good for Remote Sensing forum skeptic team
(btw why don't you post there too ???)

With all that kinetic energy it will be really PENETRATING radar for anyone!
