Who knows in what range the inductance of 3 turns is?

I think less than 1 micro Henry.

Your document mentions that the tr5 emitter output should reach 5v, but the use of double-sided large-area copper-clad PCBs cannot reach 5v, only about 2v, but it does not affect the sensitivity of electromagnetic field reception. So I think that the output voltage of tr5 has nothing to do with it.

If the tuning has been done correctly, any value in the 2 - 6V range is fine, this value is not critical.

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

I privately had several positive feedbacks with some important findings.

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.
