i have some question ask about franco italy LRL please help me ........

* what is the resonant frequency in this circuit ?
(tune frequency )
* how is tune this circuit ?
*why 8Mhz frequency feed "TR2" transistor
*is the detector work in Sri Lanka ?
THANK YOU

The tune frequency, L1, C10 and base/emitter of TR2, it's in the 150 - 200 Mhz range.

The 8 Mhz signal is the carrier that is modulated indirectly by the "phenomenon", without this carrier I think there would be nothing to be amplified.

I do not know if in your country my LRL works with these values. First of all you must have a field where do the tests with a metal (copper, silver, gold) buried for 2 or 3 months. If the LRL not work changes the value of L1 (one turn or two turns or more) or changing C10. The capacitance of the joint base / emitter of TR2 is about 10pF and my LRL works well without C10 only with the capacitance of the base / emitter of TR2.

Hello, very nice project,
I like to ask you,
how long you think
will be the detection area,
For example,
If we have a single coin what will be the
detection distance?
Also how deep can catch a target?
Thank you.

Thank you dear ionios!
Unfortunately, I still do not know the answer to your question.
This is a question for FrankoItaly.
I hope that he will respond.

Unfortunately until now I have not much experience on the real ground, but only in the test field and for that I await the result of others who have realized my LRL. In real ground I found a cartridge case (I think of brass) 1 meters away and 5 cm deep. In field tests the sensitivity is about 3 m to 5 silver coins 25cm deep. The maximum sensitivity is in the south north direction. In real terrain I had several signals but not confirmed by the metal detector, I suspect because they are too deep. However accurate signals were not due to the compass or sky effect .

I make this detector but i don"t know tune for gold pl. tell me

thank you very much

I make this detector pl. tell me how tune for gold.
thank you

I am Mahinda

hi
Excuse me
PCB size is not correct.
Thank you

Hi Sneshko what about the test field? now you have 3 months
since 11-01-2015
11-02-2015
11-03-2015
11-04-2015
or we wait again the four month :)
11-05-2015
Please let ze know what he news thanks friend

HI Mr NICOLAS , IM HAKIM I BUILT PHANTOM LRL AND I'LL TRY IT NEXT WEEK, HAVE YOU A NEW PROJECT FOR US ?

Welcome Hakim sorry i havn't :nono:

Hello Sneshko
What about your phantom test field?
Here you find the test field for LRL FrancoItaly last version after 14 days by Dojranski

40 cm depth ..2 gold rings 4 grams of 18k gold ..40 days buried.. NOT 14 daus Nicolas

Helle Dojranski sorry for this mistake. 40 days Very nice but our friend Sneshko had + 5 months and not new by him !!!!

NICOLAS YOUR detector detects a lot of good.

It's gold is detected..beautiful..

So, does it find buried metals?

Hello, Sneshko, have you tested the lrl, is it working?

pictures
 

hi sneshko

i don't see pictures

thank you

Hi Pigeon, the pictures are in a .rar file on the first page, the more important question is does it work?

hey Franco,
Your detector is no better than many detectors on the market. I've even build one that detects gold coin at 1 meter depth. There is nothing LRL about what you have.

Hi Goldfinder,

you can share with us some details? The depth to which comes a LRL depends a lot on how long the gold is buried. I think it is more important to the distance at which there comes a LRL rather than depth.

Best regards
