Any more news on Testing Crypton OBMD-1

Thanks Qiaozhi
This must be a new website.

I hade the link to the first website where I had made inquires to Andreas about the Crypton.

The last news from him was that they where making more tests in different country’s over the winter months to see how the Crypton preformed.

I presume that the tests where good then?

Hi Mij

the Crypton is in field tests together with one PDK-2,in Mexico,i hope Hugo will tell us more about the Crypton.

i´m happy that Hugo found one silver ring with his PDK .

Hi Morgan,

That’s good news about the Silver Ring found with the PDK.

I hope that more good finds will come.

Hi Morgan,

There are a lot of founds in Greece,but people are afraid to post here about that.
anyway it will be interesting to explain about depths and distances.
And most of people who was looking for WWII gold become surprised to pick muck more old old objects...

The signal at Greece is very low compared with the signal at Portugal.
I worked with 2 PDK constructed by you but no good results. They was the same with mine, not clear beeps as at your videos or at MIJ video.

> The signal at Greece is very low compared with the signal at Portugal.

Great, so the very critical and high-complicated fine tuning was for nothing...

Vice Versa this will mean that a Greece-tuned detector will have either very low or far too high signal level in Portugal.

And you can't make it universal-adjustable without knowing the reason why or in other words - what energy really gets detected.

That's why it's so important to find out the principle behind!


Compare it with a TV that doesn't work anymore.
The repair service first has to find out the failure,
otherwise you can throw away that TV-set.

Its one of the very first and basic principles of electronics:
First you need to know WHY and HOW it works,
next you can built something reliable working with this technique.

Otherwise you are poking around in the dark.





13 months later and Crypton Minis for sale now - any new results?

I believe that if we could have less frequencies in the air the result would be completely different for LRLs like that.
Probably Morgan could come over to Greece sometime and try and adjust his PDK for the conditions over here.

about PDK-2.1

Hi

the PDK-2.1 was already adjusted to Greece,i made a few adjusts in the circuits and a new coil.

I receive very positive emails about performance and finds,and many people want to buy PDKs but I realy dont have the free time to build this LRLs...

The VHF problem was solved with better transistors and changes in RX coil,this way no need VHF transmitters in the area.

I see Morgan.
I realised that Crypton works best after it gets dark and the difference is dramatic.What do you think happens in this case?

Hi

as I remember ,Geo recently made a new thread somewere,telling about a friend who found silver coins with new PDK-2.1,i supose the new PDK with more power. So the PDKs tested by Geo was the previous models(not so powerfull) who are working using the VHF electromagnetic waves from the TV transmitters in the area,anyway this previous PDKs can pick very easy gold or silver objects size of soda can 33cl whitout any VHF transmitter in the area,and if very well calibrated is posible to locate single coin too.

The sucess with PDKs on finding small objects depends on the operator skill to adjust the FINE TUNING,this is realy very dificult for some and easy for others with more experience.It is possible to build the PDK with good voltage regulator to make it very stable and avoid the time to time calibrations,however this construction is dificult ,more expensive and the PDK need more battery,as result it become heavy to work.
the PDK-2.1 is weight less than 1 kg

I see Morgan.

well,maybe the Crypton have interference with the day light ?

maybe the Crypton works with some INFRARED system ? and the day light confuse the device.

or many other possibilities...

OH what a coincidence !!!


The AM and short wave radio stations also have a much better signal
starting in the evening til the morning. The reason for this phenomenon
is the reflecting ionosphere! Another coincidence!


LW (153kHz - 279kHz)
AM (531kHz - 1611kHz)


This correlates even somehow to the Morgans VHF claims.

Especially in the autumn time you can get VHF over-wide-ranges,
any ham and amateur-radio person can tell you this.

The AM ground wave is direct, the space-wave is ionosphere reflected.

The main reflection effect the ionosphere has is from 500kHz - 50 MHz.


Longwave from 50kHz - 200kHz is little affected by the ionosphere
and has therefore little field-strenth-difference day VS. night-time.

I experimented while it was summer in Greece and the best time to use Crypton was definatelly in the evening.While detecting on the same place beeps were always less than daytime and you could easilly understand which ones where repeating on the same line.

This is not the best case if the MD is already adjusted for Greece and the testing people there still get bad results.

There should be a special poti for different countries or for a wide adjustable range.

If the feedback really is good prove it with a scientifical made test.

> The VHF problem was solved with better transistors and changes in RX coil,this way no need VHF transmitters in the area.

What is this, an FM-Radio?
The TV VHF radio stations broadcast at a band from 50-75 MHz and from ca. 200 to 500 MHz.

And the digital (before analog) SAT Signal is at ca. 10GHz.

I doubt you will receive with this 60kHz Longwave Receiver any VHF at all and also no SFX (special effects) from VHF.

This is not good, this is a lack of sensitivity.
There should be a variable transistor or capacitor etc. to tune it at daytime to an useful sensitivity.

Otherwise whats next: A Crypton model that only works usable if the full moon is shining?
