It is difficult to detect metals. I wonder if anyone in the world has ever succeeded?

I am very responsible to tell you that after hundreds of experiments by many of us, including single-panel and double-panel, we have replaced various capacitors and transistors, and finally came to the conclusion that it may ring in the wild, but it is not right. Metal responds, it only responds to electromagnetic fields, such as dialing mobile phones, electric sparks, but underground metal cannot have such a strong magnetic field, and underground metal has no electric field. No matter how large the electric field, it will be displayed underground, including powerful lightning. As long as it enters the ground, it will disappear. A small number of people say that metal has been detected. This is an irresponsible statement, even to hype their products. So far, no LRL is really useful, so you Don’t worry about suspecting that you haven’t done it well, because it is useless in the first place, so you can never do it well.

The fact that there is a resonant circuit (L1 / C10) implies that in some way the frequency is important and in my opinion there are 2 possibilities, one is that the phenomenon emits in a wide range of frequencies and therefore also in the FM range (about 80 - 110 Mhz), the other possibility is that the phenomenon interferes with the signal emitted by transmitters in this range but in this case the lrl would have to detect this signal source in a directive way, which does not happen.

For so many years, I haven’t seen you make a decent pcb. A decent machine. I haven’t seen you make a video. You don’t even know the value of the inductance. What tuning are you talking about?
