I found this on an American site where someone found it on a Polish website. From what I could understand, of the message accompanying it, the Polish site no longer exists..

Schematic, Block Diagram and PCB..

Hello evlstrike . Thank-you for adding this to our forum . The reason why this is a good thing to do right away is I have just noticed that some great european metal detector[electronic forums/ websites] have shut down . With no Warning and they even had hundreds of active members . So it might be a good idea to post more foreign metal detector schematics/projects so they will be safe here , and then can be copied / saved by our forum Techs / hobby builders !!! I have some more I will be adding now to the intenational post here . Thanks again.
HH..............Eugene

I'm interested in the names of blocks in the Polish block diagram.

The ones I did not translate I think are self explanatory... However, I hope someone who actually knows Polish will give a second opinion...

UKLAD
ZEROWANIA - Control System

PRZELACZNIK
ELEKTRONICZNY - Electronic Switch

WZMACNIACZ - Preamplifier

PRZELACZNIK
FAZOWY - Phase Switch

ZASILACZ
STABILIZOWANY - Stabilizing Power Supply

Since my hobby is design of TXs, RXs and antennas for QRP amateur radio, I'm trying to draw general block diagram valid for all VLF metal detal detector and to answer the question "How should the best VLF MD work?".
This is my proposal for names of blocks and controls in the Polish project.
