Congratulations
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??

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

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.

Cave Frequency
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????

ИГА-1
Quote:
работает измерение сдвига фаз - около 6-10 кГц (настраивается в зависимости от применения прибора), а размер антенны - порядка 10 см.

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".

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

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.
