Does anyone have inside Photos from PGF 170, for analyzing Works method or prencibe ??

Can share here ...

according to its size , I'm sure it's an IR optical system !

according to a the video that andreas presented and showing device performance,
it is not IR optical detector. he says device uses UHF band and by noticing to video,
it is clear that the detector is just a receiver which i think it uses available transmitted
radio signal in the environment. TV stations transmitter signals or other sources, i do not know. but it seems to be RF receiver.

unfortunately, couldn't find any picture.
but we can guess some
there is a knob on the box and first he turn it until tune device
the position of knob is seems to be variable capacitor such as available in MW or SW radio.
also he says if gold target is less than 5 gram, device can not find it
seems density of target is matter and size of surface is not important
also he says it is short range detector something around 2 or 3 meters from target
when put these signs together, i think the result is a kind of RF detector which uses
high power signals which transmitting by radio or TV stations

Why You thinks that use UHF freq. , can also use so like RF receiver MW or SW band ,

İf this Detector is from only UHF Receiver , then will use any UHF fix Freq. and special Filter only for precious Metals , I think so .
And knob can Variable Cap or Potans for Threshold gain .

good day

Here are a few measurements. hope to be useful for who interested to study Alonso-andreas PD.
Please notice that written values are all approx. values depends on ?measurement device?, ?how to wind coils? and ?what size of wire used to?.
Anyway, in any condition, I do not think the result will be out of the ?given range?.
It seems presence of ? UHF ? signal is vital for device to work as a long range gold detector and Just by making and assembling, device just works such as normal metal detector and not as LRL.

Once again: the UHF influences is taken from a video by Mr.andreas Christi, which is about ? pocket-size remote gold detector ?. This video available on youtube at his channel.

Here I must say: many thanks to Mr.andreas Christi from Greece also special thanks to Daniel for wiring diagram.

Here are a few pictures:

Adreas new pocket LRL
 

this LRL is working with IR/UV LEDs ???

I see video now, its other system LRL

Morgan, some questions about your famous original Alonso PD.
The PD detects massive metal targets (like cars) from a medium distance? say 3-5 meters.
Also when it finds a good old target, if you hold it stationary, has signal?

thanks Morgan.
so in conclusion ,the Alonso PD is no-motion and detects very big metal sheets etc.
I'm asking this because I had this "strange detection distance" with the ToTem (tuned in limits as you say).

l1..45...l2 380.......58and68khz

those who manage to calibrate at 66khz will have success

two ferrites..
adjustable between them

Good day
66 KHZ receiver or transmitter?
if you notice to values given and written on the schema, by calculation other frequencies
will appear. practically as i measured by oscilloscope, not much difference in calculation
and in performance.
something is missing in alonso-andreas PD. there must be an "extra factor" which has crucial
influence that PD need it to work and detect even fresh gold under ground.

I'm not really a big fan of the Alonso PD , and I know the basic info about this detector ,
but I don't remember Morgan or Esteban saying that this PD detects fresh gold.
(is here, in this forum, or elsewhere, such a statement from them?)

the Alonso PD locate a gold sovering 8gr in air test 30 cm

thanks for the info Morgan.
Personally ,for sure, I would not classify this 30 cm, as a long range detection.

THE ORIGINAL ALONSO PD
 

this is AIR TEST on a gold coin, if the same coin was buried in the ground for 10 years ,get 3meter, 100years maybe 10meters,

see distance I get in a silver bracelet buried at 40cm 7 years ago, 6 meters

I'm talking also for the air test.
To be more clear, 30cm detection distance on air test, it's not a long range detection for this "fresh" gold coin.
Simply it's the expected distance from a typical metal detector.
In my opinion, Alonso PD is not a "fresh gold" detector, regardless of the advertisement of some clone makers.
