fisher 1210x metal detector

   What do you want ?   Fixed ?  What's Wrong with it ?  Does it work at all ? 

Looks like a pretty Basic VLF.   

Between the Schematic and the board you should be able to find the values hard to see on the Schematic.

Here is the Coil Spects.

Fisher 1210
Rx 6,48mH / 15,3 Ohm
Tx (1,64mH / 7,7Ohm) + (1,62mH / 7,5Ohm)
