NEW PD MADE IN GREECE

One clue for you

See one thread by Esteban where he is talking about one old LRL made by him,but with problems,he catch pieces of iron from fences very far away,he explain how to solve the problem.
I will try to find this thread.

Couldn't remember where it is???? Can you find this subject ?

Hi Morgan
About the clue, may be one of them, is around frequency tunning, like this post by Esteban?

"If you put effort in it, you can. As Randy said, a good coil is necessary. Also adjust the resonance the max. possible, at pF range. I use off-resonance type. I use capacitance box and adjust the pF range with trimmer. "

I bealive that first you must ume on the correct frequency and then work on sensitivity.

yes Nelson,you are right,i try many coils and the ceramics pF until the PDK start locating smaller targets. I have the advantage to heve my field test with gold buried long time ago,but for you and the others how is possible to do this ???
Anyway the project presented by Esteban and Aft_ is already enough to find large objects,believe me.

There is one PDK calibration where i can locate one large gold coin in air test,20 m,and 1,5V spark 1,40m,and everybody can do this,dont be lazy,regards.

sorry,large gold coin 20 cm from the RX coil,not 20m.

Thanks Morgan.
Now i began to understand this. My proyect is underconstruction, but when i finish my pcb that i send you, i found that it has a few errors, son now i m trying to fix this before i start to make the antenna and then my first test.
I also found this link that sales a VLF receiver that goes from 200 to 11000 hz and i don´t know if this could work to experiment on long range detectors too. This is just curiosity, cause now i m focusing on building a PDK.

there are a few errors in your PCB,i saw two IC´s,but should be only one,when corrections made,send me again to analize.

This VLF receiver is maybe good,i dont know,i´m so happy with PDK that completly lose interest in other projects .

finaly no need this dificult calibrations in the limit i done before with Alonso´s Pistoldetektor, the PDK works fine even in low sensitivity.
It make the batteries empty in 5 hours of searching.

HI Morgan.
Yes you are correct, my pcb has lots of errors, so i started to build it again a new pcb, that i hope to finish this weekend. Indeed i will also modeling the circuit with Multisim and after that i will draw a new pcb.
I m happy you got PDK to work, so now i wich luck finding a new treasure.

Wow, it has a big battery drain, but i think it doesn´t maters.

Oh yes,and then of course,the SKEPTICS avaluation
No problem at all...

When you recovered the small (shoe) treasure, did you only use your PDK? Or was the final recovery performed with a metal detector?

I locate the place with PDK,i pinpoint with PDK,i use the metal detector in this spot to confirm,but no signals,i dig 35cm and found the small object.

One good metal detector or pinpointer is allways useful.

If i understand well you use your metal detector to the pinpoint detected by the PDK and detect nothing at all , you just detect the "shoes" with the PDK ....i am right???

[Alexismex]

At this distance your detection of the "shoes" is exceptional !!!!!! a true phenomena

I did not know if i am crazy but , i think that the reaction in the forum is very poor !!!!! nobody seem to believe this detection .....o.... nobody is conscious of the reach of this equipment "PDK" .....
