yes, the PDK is hard to dominate becouse of the high level of capacitance, however once you find the right place for the coil you get it mastered.

Since some people decide to expose the circuit of the PDK-2.1 model, the unique secret that remains is HOW TO TUNE THE COIL, for this process you need to build the PDK exactly like the model I build,becouse this is the best arangement for mastering the electronic components that irradiate capacitance, I have tried diferent shapes that was impossible to control.

Once you get this correct shape , need to have a buried test to try the PDK, the tuning of the coil start with a 6N8 cap and you need to move slightly the coil up or down until you can pick the signal of the buried object, if there is no results you need to try other cap value until the receptor coil can catch the PHENOMENON, as you can see its hard to do...and unforyunatly you balance and tune the PDK for your area, if you go to search to other country with the PDK maybe not work, its like IMAGINE YOU GO WITH A METAL DETECTOR USING A FIXED GROUND BALANCE to a remote area where the ground conditions are completly diferent, the results are poor,YOU NEED TO TUNE AGAIN THE PDK.


As to the most asker question,WHAT IS THE STIMULATOR IN THE PDK-2.1, the right answer is the arangement of the electronic elements at the correct disposition that play as stimulator,and by ajusting the RX coil more far or more near the circuit this act as a stimulator for the coil,or FERRIT also can be used.
