Real clone Alonso-PD

[Bill512]

......
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?)

[Morgan]

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

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

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.

A copper coin with similar diameter, is detectable from Alonso PD and from what distance?

[Morgan]

PD is made with metal detector, mixed with electromagnetic/electrostatic passive receiver,thats the circuit who play has LRL in buried objects.

Good day

here is the measurement of double 45 Turn coil of receiver in alonso-andreas PD.
please notice that the value is approx but within the range
you must position this coil on omega TX coil and nullify the received signal using oscilloscope.
however, it's function is disputable. is it necessary? does it have a role in remote detection? or it is just for IB detection part? can i omit it? ( seems possible)
anyway, here is the approx value.

Hi to All , Does here Alonso Passive Receive Coil is 2x45 Tour in same Way , and in Total will be 90 tours ? OR
45 tours to one Way , other 45 tour is in Reverse Way ?

[folharin]

you are all wrong on the laps

[humhum]

you are all wrong on the laps

Ok , What is Correct for this Laps ?

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.

here you can see 181 khz which measured by oscilloscope.my device

you did nice work . Alnso PD in hi sensitivity is unstable .

Mr.aft_72005
Thank you for admiration. Thank you
About instability in Alonso-andreas PD, I disagree with you. In my experience, it is stable.
As picture below, I made transmitter and ferrite rod receiver in blocks and separately.
Despite andreas that said transmitter is powerful, I say no.it is not powerful also it seems
Does not have influence on task or to say it does not have role in target detection.
Anyway, it is discussable.

good day

here are a few pictures that shows 3.5 cm receiver coil
it works just in IB detection section and i think it can be omitted. also its receiver part can be ignored.

i think,not necessary to have weak normal metal detector here.

obviously,for many, it is very easy to make this coil but perhaps for a few is unclear from schema.
just took pictures to illustrate it. hope to be useful.

important: please notice that for adjusting this coil (receiver) on omega coil (transmitter),
you need oscilloscope.

What I said you was my experiment some years ago .
From what distance your PD can detect small coin ??
