Testing PDK 2 In UK

[MIJ]

Hi

This is my video of PDK in my garden testing the 9ct gold ring; this is walking to the east.

In this video I am walking west.

Notice that not all the time is beeping.

I think this makes it harder in the field especially as you don’t know if precious metal is there?

Better that the beeper gets faster the closer you get to precious metal?

I wonder if Morgan could modify the beeper to do this, as this would be a great help in the field.

What do you think?

hello mij.how long time is the ring in the ground?

Ring in ground for 10 years

in UK work the analog vhf tv stations or is digital?

Hi MIJ,
These are interesting videos you made.
We can clearly see there is beeping as you walk toward a location that has some sort of weathered white thing on the ground, when walking from the east or west.
We also see that when you are pointing the direction of the white thing, the beeping happens most of the time, but not always.

In order to better understand the conditions when we hear the beeping, I have a few questions.
1. What is the white thing?
What material is it made of?
Is it lying on the ground, or is it pushed into the ground?
How deep does the white thing extend into the ground?

2. How deep is the 9ct ring buried?
Is the the ring buried directly under the white thing?
What size is this ring (typical ladies ring, men's ring, Large men's ring)? Approximate weight?
Is it a simple loop shaped ring, or does it have some intricate ornamentation or patterns which do not conform to a simple circular loop shape?

3. Are there underground pipes in this area? (metal or plastic pipes for irrigation or for water supply or drains)?
How far is the nearest underground pipe from the place where the PDK is beeping?

4. Is there anything else underground in this area other than the usual soil and plants that we see growing?


Best Wishes,

Hi JP.

I will try to answer your questions –

The white thing is merely a sea shell placed on the ground above the target “gold ring”

The 9ct gold ring is buried at about 150mm/6inches under the ground, and 3ft to the right is a cut half medieval hammered coin, and a further 3ft to the right of that is an old copper penny, under the willow tree “this tree wasn’t there when I buried the test bed” all three items have been buried for over ten years “as a test bed for my metal detectors”

The gold ring is a standard gent’s type, with a shield shape front about 2grams.

There are no pipes in the ground in the target area; the nearest pipes are clay salt glazed drainage pipes at the top of garden about 20 meters away.

I can detect the ring with my metal detector and placed the shell over the top, so I know that the PDK is picking up the signal fine.

The signal from the PDK starts about 10 meters away from the ring “I think this is good”

Regards

Hi MIJ,
Thanks for the answers.
It is interesting to see how big that willow tree grew in less than 10 years.

I can see there is no interference of targets except possibly the other items in the test garden.
I am wondering what effect these other targets have on the PDK beeping.
Since you are hearing beeping from as far as 10 meters, it raises a doubt that perhaps the hammered coin or the copper penny may have some influence on the beeping.
I am sure you made some tests which showed that you were hearing beeping only from the gold ring.
Of course I do not know the responsiveness of this locator when it comes into range of copper or silver targets.
I wonder what would happen if it were to come near only a hammered coin, or only near a copper penny.
Would it beep for those targets if they were buried for a long time?

There is one idea that comes to mind:
Perhaps you could make a test to see what is the response when you walk from the north and from the south.
Maybe the beeping pattern will show us something new that we did not see in the east-west test.

Excellent videos, by the way.

Best Wishes,

Hi


During this time i made so many field tests with PDK-2,and of course found many objects,90% of silver.
After that i still learning about this LRL...

One thing i´m 100% sure,it need some source of VHF electromagnetic waves to make the locator more powerful,the other thing is actualy in my country the VHF stop,and imediatly i note one break in power of my PDK-2 and PDK-3,losing 50% of the power.
What i realy dont understand is why gold or silver sometimes emit the signal stronger to east,other times to south, but i´m sure if VHF waves are present ,the signal is stronger in the direction of the VHF Transmitter,this is very well confirmed during all the tests and field search.

Other thing you can confirm in your gold ring test,if one person stay above the gold ring,your PDK-2 cant locate the ring,this means the body mask the wave that PDK is responsable to pick,this is very interesting,and i said to PDK owners to avoid people in front of them when searching...

Actualy i´m building one other diferent kind of PDK,that i believe it will be much better,but is still a prototype,anyway with this one is possible to go for remote areas without any kind of VHF or RF waves and the locator still locate gold/silver,the two metals that not create patina underground,i think the reason that is possible to locate them,and other like Iron,lead,bronze etc,they create the patina that insulate them and the PDK cant pick signals from them,they are like rocks underground.

Hi Morgan.
Last days i experiment with transmitting VHF signals by the sweep method. I transmmit the signals continuesly 1 week but i have not good results. I have some strong magnetic fields 3..4 hours every day and nothing else. Maybe we must use vlf frequences. So from next week i will try to modulate the VHF signals with 500 ... 1000 Hz and to repeat the experiment
We see.....

Thanks for this VHF experiments,i built two VHF transmitters and one of them stay two days near the buried target and no results .
Now i´m working in PDK-2 modifications,this device must be completly independent of any VHF.

here is one picture by Hummmhummm,explaining (just theory) how electromagnetic waves and Passive Receiver works :

[ercan]

VHF radio signals can not handle more than under the ground, the ground will make the reflection.
GPR antennas so you can work close to the ground.

Ercan_usta , Do you know VHF waves and this theory how works???? maybe you build your LRL or PD .
