??? Really appreciate any help I can get here... I bought a Techna TR7 metal detector long ago...

You use 2 knobs to adjust the detector -- red indicator for metal -- green indicator for coin...

I used it mostly for finding lost keys -- or metal which I needed to find -- Have instructions...

My grandson entered the picture and just had to play with it --- oops it's broke...

I tryed to fix it but pulled wires off inside unit -- need wiring diagram to repair it...

I tryed to buy a carbon copy of it on eBay -- got outbid -- very disappointed...

I tryed to contact the parties involved -- just ruffeved eBays feathers -- not good!!!

Techna is or was made in ElPaso,Texas -- but is no longer in business --Please Help

Post a photo of the wires and the place they detached from. And then maybe I can help you if you know how to solder. Use the MACRO mode and also take a couple of full view close-up shots if you can.
