Hi Everyone!
Have somebody experience with custom coil winding for MD detectors with IB (impedance balance ) type? I started a new project and i woud like to wind a custom coil for my MD type 3009B an 5008 (who knewn by Harbor freight 9 in U.S. ).
Those detectors are copy of fisher 12xx series metal detectors.
Best regards:
Laszlo

   Do not have anything on those detectors.  Not so sure they are Clone or Based on a fisher. The Chines do strange things Semi Cloning.  The outside may be simular but the insides a complete different animal.

Coil would be doable if you had the basic Requirements .   More work then the detector is worth I would think.

Here is a Fisher setup for the 1260?  I think.  At the time I collected it I just needed the Pin Out.

Great! Thanks!
I have the plug pinout with oscilloscope right testet. I know the pinouts. The resistance what have i read is the same we your document.
The important information for me is the coil in mH, because this must be the same. Dont worry, i had look around the pcb, some machine follow the original schematic with poor constrution feature.
Thank you very much the fig.
Laszlo
