What similarity ?, what differences ?

Yes , my intention was this system "Absorption type PD with transmitter ."
Thanks for your opinion , as there are some LRL expert here , maybe didn't
Like saying more in the matter , any way …… .
Best regards.

I supose the ICONOS is also Absorption LRL with RX/TX ,only the gold sample is in diferent position for better resonance.

This pic aren't Iconos...

Maybe this one...

I see you know very well each part of the ICONOS...

Can you show better resonating chamber to adapt in this LRL ?

Hi Morgan
Yes, I know dch85 . are you know "what is transmitter working frequency" ?
Other thing, the blue coil housing isn’t dch85 , it is pistol
Detector which built by Esteban .
Best regards .

Well,this one build by Esteban works more sensitive than DCH 85 Mineoro.

No,i dont know the frequencies...

Hi Esteban
Surely there are many other PCB, but the heart it's the head with coils, the other circuits I think they work with DC signal, perhaps there is only a coil, the Tx coil, or other ferrite coils in the control box?
You say that the loop is not critic but it's surely tuned.

There are not TX in this machine, except the stimulator coil for the loop.

Mmmmm!!!! The resonating chamber is OK. Improve electronics? Maybe, always can be improved.

Hi All
1- 4 wires to head, red= +power, black= -power, the others not shielded then DC signals, one perhaps = V/2 power.
2- Tr coil it has many turns, then the frequency may be 1 Mhz, to the
maximum.
3- In appearance it seems that there isn't a Rx coil and the ionic sensor, located near and out of Tx coil, it's the only generator for Rx signal.
4- The loop around the head, with a single turn, it's tuned with small inductor e capacitor, then his resonating frequency is at
least 10 Mhz or more, surely a harmonic frequency of Tx stage.
5- The loop it is connected with nothing but a change in inductance
or a change in the surround electric/magnetic fields it
may change some parameters in Tx coil or in the sensor.
6- There are few electronic components, surely a transistor oscillator for Tx coil, a sensor amplifier and a germanium diode (high frequency rectifier) and IC (a DC amplifier).
Some other ideas?
Best Regards

The circuitry you can see in pics is only a part. There are main PCB into pistol box.

About point 5. the tune coil connected with nothing is an accelerator of the detection. This is not critic. The accelerator was discovered by Alonso and Toto Coronel in 1959, 60 or 61, don't remember very well. When detector use this, we say: "Totorized".
