Hi to all diggers

I need to repair my Excalibur the schematic diagram. My Excalibur is 1000 with 8" Coil, but if you have the new Excalibur It could be ok maybe.

Is there anyone who has it? to share me please

Problem of my Excalibur could be:

1. Coil (but my coil is like new) always I washed at home after any use on the sea


2. Cable (I think is ok, I never twisted on the shaft on the advice of who sold it to me)

3. Potenziometer (Disc/Pin - Threshold - Volume) the others I think are ok for sure for many reasons. Not sure if 10Kohm or 100Kohm but I read on the net that is 39SA-1RB-103-ND with the cut on it.

4. Quartz (I think 3.904Mhz, I don't think it's Khz)

5. Microprocessor I hope it's not due to the fact that temperatures are not high inside

6. Board

7. oxidations water humidity and condensation on the boards (I don't think so, boards are very clean and no oxidation I see on boards

These are videos I made:

Could you help me?

I need the schematic diagram of the circuit of the Excalibur 1000

need to know where to find the exact potenziometer of Threshold and if it's really 10Kohm or 100Kohm

THANKS A LOT IN ADVANCE

Not sure these parts are readily available to the public, sounds like you might be better off contacting minelab. Even then, they dont supply diagrams for their electronics like that. I tried getting them to repair a CTX wireless module, or asked if they had parts for me to fix it at home. They're answer was NO and NO :laughing: but what do I know, I hope I'm completely wrong and someone knows where you can find the diagram you are looking for. Good luck!
