Schiebel AN-19/2

I have one in the basement but why do you want to loose time on such old technology? Air tests showed nothing impressive and exciting. I just like the box. Its very well built.

guys, you want to feel what is THE high resolution picture? read my opus again.

i can make a lot of picture if you are interested, but i don't have time to draw the schematic. It looks very complicated, and surf pi or baracuda is superior to this md. each detector have it's own purpose.

I am somewhat surprised that this one wasn't turned into a project by anyone here. In case anyone is interested towards the very end of the attached document are the various test points for the PCB.

if you can post all values from all parts we can build one
i have an used coil here too, coil works also with other detectors

I had one for a while, but did not get on with it and sold it a while back. One big problem is that most coils were unshielded, although some later ones had shielded coils apparently. This means that unshielded ones false a lot on a wet beach. Another problem was that the threshold drifted negative, so you would gradually lose sensitivity. Any re-design would benefit from a self adjusting threshold like the VMH3CS.

Cool I posted info on a Old one last week.

Good quality metal detector. I attached some pictures and technical specs. I do not have schematic. It is non motion md, volume and sensitivity pots, nice connectors, rubber gaskets for battery compartment and front panel, nice strong shaft (half aluminum half fiberglass).

I did some air test's inside room and it sees a gold wedding band at 30cm. I took the detector outside, far from any metal and I can't reach the threshold limit, sensitivity pot being at max clockwise. With this settings i got only 15cm for same gold ring. Better ask here before i start playing with the trim pots from pcb. I was thinking to add a series resistor with the pot.

Thanks
