You forgot to show the transmitter, frequencies of Rx coil, battery compartment and Tx coil.
This has always is uncomplete. The box does not below to the full pdk schematics and you know that. Please be honest and don´t fool and confuse members has always you do.
A passive PDK has very short range of detection and a good machine has a transmitter stage, RX stage, RX amplifier stage, etc.
Why you don´t teach to members real thru for example about how to tune PDK?
Morgan give us real information, at the end we are not stupids that bealive all what you said.
Why you don´t tell that a guy from Mexico that brought PDK couldn´t make it to work?
even this picture can tell a lot,and there is nothing more than your circuit with some modifications,oscillator+toroid and a tuned RX coil...
is not enough to understand? there is no magic,its one open book (for those who can read)...
