ИГА-1 Russian Long Range Locator

[Dubulumach]

My friend Geo has right !

Use original Russian IC's and parts and make IGA1 work. Schematic is 100% correct.
Remember NOISE IS YOUR FRIEND. HALO signal is in noise not out of him. But keep in mind without test field with induced phenomenon this lrl couldn't be tuned.

Any quality schematic with wide band noise preamplifier is best thing for detecting the phenomenon.

NOISE IS YOUR FRIEND becuase can help you to find a lot of gold coins.

And one small secret: Halo Phenomenon is season and geo-position dependent. It means if you have tuned your device and have caught pehnomenon in spring, with same adjustment it woudn't work at summer. Need retune. Also different geographical area need tuning which work only at that area. If you study original Yuriy Kravcenko schematic you could see 5-pole switch (one initial and 4 season switch). Good thing is IGA1 auto phase lock target signal once when catch it out of noise. Very probably this is one of the best and hardest LRL schematic at this forum.

I can not find the scheme either

On the third page is a diagram.

I don't agree. Schematic is OK. My Iga works ok near the city.
Far from City don't catch something but as Dragomir said (he own an original IGA) Iga don't work at all places, especially near the sea.

Good Day Geo! Have you tried on your site to discover precious metals with the help of IGA-1? If experiments were carried out, in which direction does the indicator arrow move after resetting. Thank you!

Hi.
I tried only to locate caves.
Most times indicator arrow goes right and the next time left.

[Pahom]

[/QUOTE]Clear ... and in the cave chest !!!!!! And what current consumes the device? I also began to collect IGA-1. Slowly for now, but little by little the board is picking up the details.

[Geo]

Don't remember exactly the current but it is not big. I use 10 batteries 18650 for +-15V.

Understood thanks!

I made all tests on summer but i have read that IGA works better on winter, so it is time to give it some tests more...

Yes, IGA all time works ,because not works with Elektromagnetic waves and İons potential.

My new lrl project IGA-1M.
Work only with original Russian components.This one is cave and hollow locator. Meassure phase shift at the border between two layers. Work at LF. Use capacitive antenna. Very complex schematic with multiple nested feedbacks. Work mandatory with highly polished antenna surfaces. Here is layout.

[Geo]

Hi Dragan.
Congratulation for the new project.
From my experience it works with similar american ICs (maybe a little better) except the K140UD13.
From what Dragomir said, antenna is the most critical part.

Thank you Geo !

Yes i agree with you Geo,IGA 1M need perfectly made antenna.
I need to know what kind of dielectric ring was used in IGA-1M ?


There is reason why air haven't used as dielectric insulator.




Regards!

Hi Dragan.
At my Iga i use teflon.
The reason that air haven't used as dielectric insulator is because the case is metalic so is needing at least one insulator.

[Dubulumach]

Hi Geo.

Yes teflon is excellent insulator. Thank you.

Hard to find in Serbia. Need to search at ebay. I have got 2 K140УД13 operational preamplifiers. Very interesting component. There are some secrets inside for fine tuning not shown at schematic. Email me for more info privately.
