This circuit at least tens of thousands of people around the world have done, but few of success

hi to all
i come back.
franco I got about 40 pieces of silver buried 6 months ago.At a depth of 25 cm.Yesterday I did a test.Unfortunately no results found.I tested a different direction & with variable cap Again, unfortunately,i did not resultI am disappointed with this device.
What do you think Franco??????????

Don't despair, there are too many people in the failure, continue to work hard

Hi Mustefa,

may be you have to try different combinations of L1 / C10, you must also check that the LRL has the maximum amplification possible. As I said you have to adjust the gain until you see the effect compass and then reduce it. You've got the compass effect?

Best Regards

I think we have to do a transmission circuit, use this circuit as a receiving circuit, maybe the effect will be better

What is the purpose of the compass effect?

What should it be?

The compass effect is a drawback which occurs when there is too much amplification and is not due to a malfunction of LRL. You can avoid only by decreasing the amplification.

I noticed when building Franco LRL we have two type of receiver
The first is very sensitive to all that is static or magnetic
The second is not influenced by electromagnetics like television, on the other hand it detects the scalar field as the spark of an electrical contact .
Naturally it is the second that reveals the phenomenon
Mr Franco
How to convert the first LRL to the second LRL ???

Hi abdou2014,

My lrl has only a type of receiver, the phenomenon is picked up by the antenna and it is an electromagnetic signal or an electrical signal.

Best Regards

Hi Mustefa,

The compass effect is due as already mentioned the excessive amplification and manifests as a signal that occurs in the north / south direction always with the same intensity by moving in this direction.

Best Regards

Because of the machine, I got a huge wealth, I detected a lot of gold and silver and bronze, if you haven't succeed in doing, you can ask me why, I will guide you how to adjust

Voltage output size is no relationship, if you are using a single sided PCB its output voltage is much higher than the double coated copper PCB, the key question is how to capture the metal signal
