Yes, dear Franco.
A bronze dagger 40 cm deep in the ground.
A silver bowl at a depth of 240 cm in the ground. Yes, 240 cm.
Two silver coins at a depth of 70 cm in the ground.
A volume of gold coins in a jar at a depth of 90 cm in the ground.

All findings are from 2017 to 2022.
All in the country of Iran. In the north of Iran.
.
.
And many other findings that are surprising in terms of the depth of burial in the ground. But if I say it, no one will believe it.
This profession is prohibited in Iran. The details of the research cannot be mentioned, but if you want, I will tell you in an email and you can transfer it here.
My English is not good. Forgive me

Hello, dear teacher Irfan, I hope you are well. Are you still working with Asman border? If possible, give me a way to contact

Hi dear friend.
Yes, I always try to get the effect of the sky, but it is not absolutely necessary.
That is, if the effect of the sky is not detected in a certain place, if a valuable metal is buried there that has a long burial life, it will definitely be detected. You just need to reach the maximum sensitivity in the way of settings in that place.
This is an empirical value

Hello Nicolas, I want to try the Franco lrl circuit diagram, but I have a few questions that I want to do on the copper plate, can I ask, can you help me?

Default I couldn't figure out the logic of 8 Mhz crystal.

Hi FrancoItaly, I tried the circuit you made and got positive results, but I couldn't figure out the logic of the 8 Mhz crystal in the circuit. Would you mind explaining it?

The 8 MHz signal serves as a reference for the mixer, to have a stable DC output even in the absence of the phenomenon, the maximum sensitivity is achieved with the 20 MHz oscillator and by adjusting L1/C10 on one of its harmonics to have the maximum signal. The 8 MHz oscillator has harmonics that are too small to use.

In contrast, it will absorb and pass the harmonic signal. What do you think of this filter? I think the signal is treated like high frequencies, microwaves, similar in small capacitance. with a low pulse. Is there a comment.
Hello, Mr. Omar. I follow your content. Your ideas are great. Those who have a deep understanding of the phenomenon and its effects can understand your ideas. Your idea about molecular vibration is quite practical. There are many subjects in physics and electricity that are not taught properly and conceptually, if you research about making a plasma capacitor, you can make your desired sensor. In my opinion, the effect of the phenomenon is nuclear magnetic resonance of metals, which occurs in the earth due to triboelectricity.

Let me give you some advice, I tried it and got positive results, make a frequency filter circuit at the antenna input, it works very well for discrimination.

Hi friend,
can you present it frequency filter circuit at the antenna input and its connection?

Question Antenna Tuner Freq for 20 MHz

Hi Dear Franco
In 20 MHz Version, you used LC circuit (C10 & L1) as antenna tuner. if we assume L1 roughly about 50nH (3 turn air core, 10mm Dia, 15 mm length) and C10 from 10pF to 100pF then the resonance of tune circuit will be somewhere between 71-225 MHz .

Resonance frequency supposed to be around 20MHz or I missed something...?

Post Antenna Tuner Freq for 20 MHz

Even if we assume L1 as two 100nH inductors in parallel (Equal to 50 nH), tank circuit goes from 50-160 MHz .
L1/2 and C9 forms a high-pass filter with cutoff frequency 21.268 MHz .
