As Enjoykin inform me the inventor of IGA-1 Yuriy Pavlovitch Kravcenko has passed away 2016 year in Russian town UFA.

Mr. Geo, can you share IGA-1 circuit?

[Geo]

Read all the thread and will find the schematic...

[Geo]

The project finished
I solved the stability problem but found a new one. Sensitivity is not so good.
Maybe i burned the Mos K140UD13.
I am looking to order some new but the shop that i ordered existings ICs there isn't at ebay now, don't know why.
Any way one more photo

Dear Geo. You always modified and invented a lot of long range locator. But you never sell any of them. at least Do you use them in field? had any good results? Do you tell us what kind of lrl's do you have and which one is your favorite. Do you have any lrl suggestions to us? I am standing very near to you and go to Greece often. If you suggest any lrl which you can modify i can buy it and go there for meet with you face to face. If you do this as a job i can pay your hand work. I hope you dont missunderstand me. I am just asking you a favour and want to know your situation. I just want to have real working lrl and i tought you are good at this. Greetings...

Hi.
Sorry but i don't sell lrls. Lrls are cheap to construct them, but need very long time to finish. I use them at fields because i am treasure hunter. More of them need very good conditions to work but other needs less. My favorites are two lrls with ferrite. They can catch an big old buried object from 300+ meters but problem is that they locate all non ferrous metalls.
If i have any photo at my pc then will attach here.

Btw... where are you from??

[ozanmelih]

Dear Geo. It will be good to send your best devices photo to forum. Did you construct (invent) or modify it? How big should target be for detect by lrl? Do you pinpoit the target well? If you modified that lrl i can buy it and come to you for modify it. Of course if you accept to modify it. I dont need very long distance lrl but can find metal (all non ferrous is ok for me) I am from Thrace/Turkey. I live in Istanbul but i go to Greece very often. My sisters husban trades in Thessaloniki. And very closed friend of us called Stavro lives in Orestia. We visit him often. Greetings

[Geo]

Hi.
Sorry but i can't make a lrl for you. No free time for this job.
Look two photos from one type of lrl.
I can't find photos from other type.
With this type i can go near to object about 1x1m.

[ozanmelih]

Dear Mr. Geo its ok. Thank you for your kindness. I hope we can meet face to face someday. Wish
you luck...

... and here my best lrl
It is not so beautiful but makes very good job.

Hi.
Now my IGA-1 works fine.
I want to use it for caves detection
Iga inventor was using dedicated frequency to detect caves, different that the frequency for aura etc.
Is there anybody here at this forum that knows who is this frequency so to adjust it????

Особенностью прибора является то, что частота, на которой
работает измерение сдвига фаз - около 6-10 кГц (настраивается в зависимости
от применения прибора), а размер антенны - порядка 10 см.

[Geo]

From what i translated you wrote "A feature of the device is that the frequency at which
running phase shift measurement - about 6-10 kHz (adjustable depending
Application of the device), and the antenna size - about 10 cm".

My Iga works from 6 to 11Khz but i need to learn if i must adjust the frequency at one that is special for caves, or anyone between 6 to 11 Khz will make the same "job".

[Mike(Mont)]

I'm no expert on this, not even a novice, but a closed chamber has a resonant frequency that is a function of it's length. So to me that means different sized cave means different frequency. Now i saw one website for frequency discriminators said void is 700Hz. Maybe you can just bump that up to 7kHz. Worth a try I guess. Or maybe an odd multiple harmonic. Or also heard silver frequency works for void, so you might try 8.6kHz

[Geo]

Mike course the best solution is to do tests, but it is not so easy.
I have read (I do not remember exactly where) that the inventor Yuri Pavlovitch Kravcenko before selling each unit sets the frequency in accordance with the use which the owner wanted . So I asked here if anyone knows .....
Dragomir might remembers (owns a unit IGA-1), but I do not see him in the forum.

Hello Geo

Happy new year 2017 for you and all forum members,sorry for the delay, I just decide to come here to say hello.

hoppe all golden dreams come true .

Hello Paulo.
Happy 2017 with health.
How are you??
Are you still at Portugal or at Germany??

Regards

[Morgan]

I still in my country, at the same place we met many years ago, of course somertimes I travel to other countries and make a lot of experiments with PDKs and other LRLs, already found some treasures,but not a big one...

Is there any plan to visit Greece??
There are places good for PDK and other very bad for it.
So will be a good experience.
