Hello,

Happy new year!
I see your link at pcb... and concluded to ask you...
can you give a schematic on this pinpointer for a repair? can you sell
a batch of bare/blank PCBs on this detector?

best regards

thanks eddy, these are quite good once tweaked, its the coils that are off.

Eddy writes on his webpage he has repeated the pcb and it is working good.

Hi guys,

Hey nice to see the schematic and the clone circuit board made up, makes me feel better about the time it took to document all the parts on mine.

I've been very happy with the way mine works now, I'll stopped tinkering and done treasure hunting instead.
The modified (coil) pin pointer is finding stuff for me. Battery life is good so far, I've not changed it after about 6-7 hours of fossicking on beaches and old ruins. The sensitivity adjustment seems good, set once and forget it. I removed the white LED I don't treasure hunt in the dark. My main detector is an X-terra 705.

Thought I post a snap of the loot
No treasure yet, but had a good time looking.

Cheers,
Martin
