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?

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

No without right accessory.

telescoping antenna is ok.

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

What is the depth and radius of this device?

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:

Hello Franco, what do you think of this circuit?

Hello Franco, what do you think of this circuit?

Its ok, I have made it

Internal fluctuations and noise

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
