Aft_20075 (modificate the Andreas PDK)
Geo (made is own version of PDK based on his knowledge)
Morgan (I made great modifications in the Aft PDK design)
So,what is the PDK-2 ? Is one modificated design of the Alonsos Passive Receiver,all this people work on it,each one develop something and UPGRADE the circuit.
The PD was bought in Paraguay where was tested and it was working there better than here,this is one good reason to believe that PDK´s work fine in your country.

Hi Morgan,
This is an interesting discussion about the origins of the pistol detectors.
I remember watching the pistol detectors from the early development stages in this forum.
The first pistol detector we ever saw in the forum was the Mineoro DCH85, which became the basis for some other experimental and commercial developments.
Some time after 2006, Esteban began showing us photos of experimental modifications he made from the DCH85 and other Mineoro designs.
The tiny circuits he posted showed that his experiments contained many of the features found in the DCH85, as well as some of the recent PDK designs (See below).
Esteban microfilm circuits posted in 2007:
It wasn't long after that post when we saw the first posts for an experimental LRL made by Andreas, showing his Dillinger pistol with a high voltage Tesla coil.
While he was in contact with Esteban during this construction, the Dillinger was not related to the PD designs like we see in a DCH85 or more modern versions.
It was based on Russian circuitry from more than 50 years ago.
Then later that same year, we saw the release of the Iconos LRL, which looked suspiciously similar to the Mineoro DCH85, both in the physical design and the circuit design.
As time passed we saw a lot of experimental frequency generators and other LRLs in the forum, but nothing seemed to show any consistent results except for random stories of finding treasures.
All the commercial and experimental LRLs at that time had people who tried them, claiming they don't work.
It wasn't until the end of 2007 that Morgan showed some circuits inside an experimental pistol detector that Alonso built.
Looking at the circuit, it was noticeably different than the DCH85, but still had some key features that we find in a DCH85.
Possibly this pistol detector was an old prototype which seemed to work better than an actual DCH85.
This became the basis for a lot of experimental LRLs which used the exact same circuit, or modified versions.
As Morgan and others made more modifications, the circuit became simpler, and began to resemble the DCH85 more closely.
Today there are quite a few of these experimental PDs in Greece by various builders, as well as some unusual variants from Morgan in Portugal.
Of course, there is also the Tubedec in Brazil, which is essentially an exact copy of a Mineoro DCH85 put into a different housing.
But what about the Crypton?
Is this another pistol detector, or modified DCH85?
From what I have seen it is not.
It does not detect by the principles used in either the DCH85 or the more steamlined PDK models.
Nor does it perform the same as a PDK type pistol.
From what I can see, this is a design based on a different theory of detection than the theories believed by current PDK experimenters.
For this reason, it cannot be compared to a PDK or a DCH85, because the circuit does not work the same.
It appears the problems that were observed in early versions of the Crypton were related to a different kind of technology than the simple coil/sample/stimulator that PDK experimenters work with.
We can only wait to see if the new Crypton Mini has overcome these problems.
Best wishes,
