Is in Portuguese language. Let me know if you want!

Portuguese... spanish... whatever... the problem is that what's in the manual is pseudo-science at best!
I think he's interested anyway... cause translators exist...
But, of course, why I made such a post ???
Better I will focus back on serious things... like understanding how the hell a rodent repeller can be converted to a working LRL... seems too new-age issue but probably Alonso made it happens in the 70's...
Anyway, what about your cousin Alonso !? Hope he's well... I'd like to hear from him directly about these wonderful (hopefully) technologies of lrl... and how to make such funky things with so few resources....
Anyway, kind regards to mr. Alonso too!

The tweeter system only was capable for to detect at few meters. I have silver recipient (maybe 250 grams) buried at 75 cm depth and was detectable very well, but at 4-5 meters. As I told you, ultrasonic also is used for to reveal imperfections in structures and other things. He has capable for to use any system come in his mind an be workable, but he don't reveal his secrets...
Hi.
Before about 15 years, one electronic engineer made a LRL with ultrasonic. He used a depth-meter for boats, he put inside 2 pcbs and the detector had the ability to detect 1kgr thin papers of gold at 100m. He made some clones (about 10) but all had the same problems, bad stability and burned a transistor. Now i cant find any clone of this ultrasonic detector. I try for it at least 5 years ago. The ultrasonic depth-meter was a Conion firm with a AM radio on it. The one pcb was a oscillator but the other ????
I wrote all these to say that i agree with Esteban, ultrasonic work for lrl but i dont know yet How????
The machine absorpts the "emission". I build a 3 antennas instrument used in origin for to enlarge a short signal million times, so this circuit was capable for to capture "the phenomenon". This instrument reveals very sensitive and stable at the point that "the phenomenon" caused for an old rifle 7.62 cartridge, used in a revolution of 1947, for example, shows a big angle in detection, but no much distance, this is "infernal" in the nearby, but when I pass the "emission area", the detection stops. Is some difficult find the target, but is there. Lead produce short beep and only you found the lead targets when you pass over it. When I build it, the first time, detect very well an oxidated nail, and I "cure" it with 15-18 megohm resistor.
Once, I walk and obtain a signal with continuity, but at short distance. I watch in the site and saw a hollow in a tree at the level of the soil. So, I "aimed" the antenna towards it and detection was more strong. Was caused by stainless steel coin and at first time was detected in lateral position! This coin material is very good and is rare to found attacked by oxidation.
When you experiment and go in the field, you can obtain response of such "phenomenon".
