hola amigo
si tiene depósitos de oro, no necesita detectores. solo una pala, mi amigo te ayudará en situaciones difíciles.

Hello friends, did someone perform the detector called Impedet?
I attach the details

i like the look of it "impedet" bears further research any other details ? coil data or full parts list as schematic is missing a couple of details and nomenclature is skewed?

[Carlos]

It's all the bibliography that I have. I can not find more information on the network.What data are missing ?. the coil is a classic for a diameter of 22 cm. 24 wire turns of 0.5 mm. with an inductance of approximately 300 uH.

Thanks carlos and yes my mistake i had the jpg blown up and couldn't see the a1- a4 in the margin

Carlos, I think I may have the complete documents for this metal detector.
I will search for them and upload if I find them.

I like the fact that the circuit uses a commonly available quartz to keep the frequency stable and precise.
I think this is nice little circuit to construct.

Sure it was... back in 1992.
It was sold in Conrad back than in 1991. as kit.

little history flash-back. literature list for Carlos.

Is that the same circuit? Well if it is, I find that the response isn't sharp enough for my liking. Could you say what is the inductance of the coil seen in video?

[Andi68]

The coil in the video looks very strange
