In any country, no one experiment success, but the Earth's magnetic field signal, cutting the Earth's magnetic field formation of the signal, not the signal issued by the metal, the so-called buried metal for a long time to have a signal, it is only some businesses in order to meet the buyer's delay

Hello Franco, if I use a capacitor MKT?

[zixelll]

Better than these two capacitors mkt . ceramic disk

Ceramic capacitors are better for high frequencies. The input stage is about 100Mhz.

Thanks, if you use a telescoping antenna, is it ok? And do you have any changes to make the device better?

[zixelll]

Does this device have a point-and-shoot feature?

No without right accessory.
You need to ad this attachment:

telescoping antenna is ok.

Lrls are not for pinpoint and no point and shoot feature.

[zixelll]

What is the depth and radius of this device?

[zixelll]

Do you have any changes to create a better device? And what is the best transistor for this device?

The version I posted is the latest and the best. I used the BC183C because I have many but any transistor BC...C is ok. As far as performance is concerned, there is not much practice on the ground, and for that I wanted to make all the details public to build. However in the ground where I do the tests, the lrl feels some silverware (bracelet and cutlery) buried at 20 cm to about 3 meters away and this about 2 months after the objects were buried and proceeding north to south. In this direction the sensitivity is maximum. The "phenomenon" is very weak as intensity and the lrl has to work at maximum sensitivity. Here are the videos of some members of the forum:

Thank you for your comment about BC109

Hello Franco, what do you think of this circuit?

Its ok, I have made it

Changing the main circuit board and bringing some parts together
The circuit does not work properly
You must make the same Franco-sent circuit

I don't agree, this is good pcb. I made this version because I can't find Separately display stage pcb

[reza vir]

your pcb has no problem
But for good result and good sense
You must create the original pcb
Or separate the parts into 2 parts pcb
I'm the best of the senses
When I got 2pcb I got it

I haven't still try the device on some known treasure place because I'm waiting for enclosure and some other parts. But its very sensitive device. I made also pdk a13 who at same place is not giving any signal. I also now want to make and Totem and than to make comparation

[reza vir]

I also made most circuit boards several times
And the result was that there should be parts
Transmitter & Sensor & Sensor & Nutrition ...
Separate from each other in a few pcb packs
And they all function in an open and closed environment
And the forest and the desert and the city are different
The most important thing that affects them all is voltage and power
For example, I got a 1.5 volt battery from 10 meters, but others are much less
I got 300-year-old copper from 2 meters with 3 lights
But when it was windy, it was very weak
Again there is so much difference with others
Anyway . I want the best for you

As I have already said, the phenomenon is of very weak intensity, especially if the metal is buried for a short time, so it is necessary for the lrl to have the maximum gain possible. The sensor stage is essentially a high gain amplifier that amplifies the 8Mhz signal generated from the quartz oscillator and if the pcb is not well realized it's possible that the stage is self oscillating. The better solution is a double face pcb separated from the rest of the lrl. An empirical way of determining whether the gain is sufficient is to verify that the lrl is sensitive to the compass effect, that is to say that walking in the north / south direction always has a signal of the same intensity and it is understood that it is not a buried metal.
At this point, you must decrease the gain until the compass effect disappears.

Does someone has realized difference when is moon full and young?
