Looking for a schematic for the vibra-probes

[wizard2406]

Looking for ideas on making a good pinpointer. Also can someone give me a link to order the GPD-902 from. Thanks,

Maybe somebody knows coil parameter:

Coil Parameter

Hi Esteban,

It's a bit difficult to dentify it "as" but the number of windings and diameter is in the schematic. L1=120 and L2=60 windings. The wire diameter is anything between 0.3 and 0.4 mm.

Pinpointer

Can you give me an other ref name or equivalence for the IC 547KP1 included in the pinpointer. I can not find it with this ref number in France. If you have the manufacturer name also. Many thanks by advance

Thanks for you help on this, does anyone have a link on this article?

I went looking for it, I guess I did not dig deep enough, and could not pinpoint it either.

Again Esteban, thanks for your help.
