OKM Inside

[tomec123]

Amen...simply the truth.

[AK48]

ok , send it to me , thank you

[Krzysztof]

I have this pdf, I can send on priv. There is an entire application.
Noise level, resolution and sensitivity of 10 to 20 nT.

[AK48]

I had no thought to look at the integrated circuit, you are clever and it is the good sensors
thank you

[Krzysztof]

The configuration of the coil and the first integrated circuit indicates the PNI 11096 ASIC in a 28pin MLF enclosure.
3-axis magneto-inductive sensor driver and controller with SPI serial interface.
Information to look for in PNI: 11096book.pdf
I built it 15 years ago, so I remember the setup.
Inside the black component there is a coil with a METGLAS core.

" There are fluxgate sensors inside the pipe "
are you sure Mr ivconic , i've got one and open it , the sensor look like hall effect but not a fluxgate sensor , let me found the pics and i'll show you what"s inside my OKM probe , so you can told me , well , i found the pic , into my probe it is twos identical pcb far 1.5 meters from each over and as you can see , the sensor is the littlle one at the edge and it's not a fluxgate sensor .[ATTACH]53254[/ATTACH]

Could be, i am not sure about that one. What's inside black component?
They probably changed technology in later models.

You are right - the problem is:
People like the glorious shine because it feels much more fascinating!

Its not for nothing called the "GOLD-RUSH" - treasure-hunters love that feeling!
Just one little step away from the huge treasure - of course ALWAYS, with a bottle of Whisky and "great" equipment. *laugh*

White-vests-scoundrels as OKM take advantage of it - perhaps some of the DEVs there are dreamers full of wishful-thinking, too.

They offer something "at least working" but the main part of the deal or "promises" and "lucrative" perspectives are based on lies!
Because digital LCD-gradiometers are not LRL, thats simply a fact but they still promote it as LRL to rip others off of 1000s of Euros.


Sames as women which are wearing Make-up, otherwise nobody would wants to have Sex with them,
especially not at 8 o'clock in the morning when they are looking really really "beautiful" ! *laugh*

The best thing is not wasting any time with OKM at all !!
Ignore them, hate them, don't buy any of their products
and warn your friends about not to buy any of their crap.

Because they are like scandalous Showbiz-Stars!
Motto: "Bad reputation is good reputation!"

Many of their products are magnetometers, gradiometers.
Decently made and usable. If operated and handled properly.
So is not alright to completely discredit all what they did and do.
I don't have problem with such of their devices, i saw couple of models and those were manufactured well.
There are fluxgate sensors inside the pipe. Operational principles are known.
So nothing indeed to complain about.
What i really can not support are bold claims in their advertisements.
And also i can not accept some of their devices as sane and proper technology.
So they are mixing, little bit of this and little bit of that.
That's bad business. Not lasting long.
Hot prices, bold claims and few fraudulent devices with even more insane claims.
If they stayed only with magnetometers and put normal prices; they would be well respected company for long time.

This is LRL nonsense from OKM. If you want to discuss these devices, then please register at www.longrangelocators.com.

Also, I have removed the other two almost identical threads that you started on the same subject.

hi ok im sory

The user interface could have been a sham, I mean when you try different modes or adjust different parameters, it does absolutely nothing different. For example, you turn up sensitivity or power setting on the screen, but it is ONLY changing on the screen, nothing going on elswhere in the detector circuit. It was possibly a contrivance to fool people for the big price.
I can recall a video on EEVBLOG where Dave tested a device which plugged into usb in car for better fuel efficiency.
LED started to blink furiously as if to show the device was kicking into action, then another LED came on to show the device is now saving fuel. When he checked out the circuit in a teardown video, he observed that the USB data pins were not even connected, only the B+ and Ground. Turns out that it was just a fancy LED flashing circuit.

Thanks!

I could write large book with real life true examples.
Yet i am not able to give the answers.
Does anybody remember Sirius pulse induction metal detector?
I have probably the most amusing story on it.
With risk that i will slowly slip into writing small novel, probably annoy, i will tell it here.
Initially Sirius was offered as semi kit for a price of 1850e.
Person D, from near neighbor country bought it like that. Put it together.
Than sold it to person E across the border for price of 4000 e.
Person E put it on local advertisement with price of 5000e.
There is a small village next to the city, commonly poor working class.
Persons A,B and C living there.
Person A, neighbor with persons B and C.
Person A bought Sirius for a price of 5000 euros !!!
He was too cocky and wanted to show up, so he spread the news.
B and C are daydreamers. Totally sure there is a buried fortune waiting them.
They only don't have a tool to precisely locate it.
As the usual story goes; such fortunes are too deep to be located with ordinary and cheap detectors.
So they expected person A to join them in such venture and with a help of mighty Sirius to locate the fortune.
However... after just few days; person A realized that Sirius is overpriced crap and that he wasted money.
Instead telling the truth; he started to tell fairy tales to persons B and C, on how splendid Sirius performing.
He showed few gold coins to them, claiming that he detected them with Sirius at 1 meter depths.
Whenever they asks him to join them and go search for the fortune; he got some excuse. And delayed.
His idea was to slowly persuade them to buy the Sirius from him. That's how he would retrieve the wasted money.
Time was passing. Nothing happening. He avoids them making various excuses.
One day he said to them "Finally i got my fortune, i don't need Sirius anymore. I am putting it on sale."
Person B and C are poor people. Working class. 5000e is unbelievable sum for them.
But the desire, itch and strong belief in existing buried fortune was too blinding for them.
So they went to a local loan shark, kind a mobster, to loan that sum. They loaned money.
Than local mentality, so typical for the small town people, started to bug them.
Why the heck would we buy it from him? He avoid us and he don't want to do us a favor, to go with us and dig so obvious fortune.
We will not buy it from him, we will buy brand new from the "seller".
So they did buy it. From person E. Making him and person D very happy.
Finally that day came. Another Sirius is there. So they went to a site. Spent a day, two, many... no fortune!
Something is misty about this Sirius? Must be something that we are doing wrong? Probably is something in settings that we don't do right?
After all; it is ultimate high tech device, right? It got a shiny large TFT display! Nice large box! Looking so expensive and advance.
Too many hard to understand options on screen. Too many parameters to adjust. Probably we don't do something right.
We will need a help from somebody skilled in this. There is a certain "ivconic" in neighbor city, people are claiming that he is skilled enough to help us.
Let's find his phone and call him. So they did. I accepted. Mostly because i was too curious to see that detector and what is all about.
One day they visited me. I was also impressed with a look of the detector. Looking sharp and expensive. Of course.
Previously i had field experiences with Lorenz Deepmax for shorter period and Pulse Star II Pro for quite longer period.
Also i made approx 70 copies of Delta Pulse, with various setups. Various coil sizes, various pps etc.
So.. more or less; you could say that i have some so so experience with such detectors. I could tell if detector is good for certain task or not.
So we tested the Sirius for 4-5 hours. I tested all the options at it. All the combinations of setups.
I was more than disappointed in what i saw. It was too slow, many lags in behavior, inert, terrible low sensitive, "shallow" at any type of targets.
I couldn't believe what i saw. Such poor performances for such high price? Or i am also not capable to adjust it right? Ok, that's the possibility too.
I told them my opinion. Roughly. Without picking up the right words to make their "pain" bearable. They left me with totally green faces.
Time is passing. Weeks. Months.
There are few local md forums here. I don't visit them so often. Nothing to read there. Most of the topics just taken from Geotech and translated, diluted...
One day a friend urgently called me, suggesting me to visit one of those local forums and read new topic. So i did.
I was shocked!
There is a story going on for weeks on that topic. I was blamed as total ignorant, "enemy", liar, sneaky b*stard... you name it.
When they left me, they phoned the person E, complaining. Than also involved person D too in the argue.
Person D is running also local forum in neighbor country.
With the help of that forum he is advertising and selling the various crap that he smuggles across the customs, for years.
So... you can only imagine what kind of mess i provoked by telling the truth to those poor people!
Like i poked my finger directly to eyes of persons E and D. And that was not small thing to do.
Huge and terrible public forum anti campaign started against me. I was the "public enemy No1" at the time.
Reading further posts at that pathetic little forum; i realized even more horrible thing!
Persons B and C were later totally turned to believe that i was the only fraud in whole story!
As well as the rest of local public. All the blame on me and my ignorance and bad intentions.
...
Than i finally realized that it is very dangerous to tell the truth. Especially when it is opposed to peoples dreams.
You can do anything... but you don't spoil the daydreamers dreams! No way!
By telling my honest opinion on what i experienced with damn Sirius; i gained so many enemies.
All the mentioned "persons". As well as Sirius producer. As well as most of the local forums public.
I was the only one to blame.

I take off my hat!

Very interesting and the whole truth Ivconic!
