Blagoevgradka Grozhdanka Grozdanka detector

The receiving coil must be polarized before recording a useful signal. Therefore, even with this type of metal detector, a clear drag and displacement of the signal from the iron can be seen.
I do not hope to be well understood but I will avoid the dispute.
The schemes that I will publish soon have been downloaded from a real working machine and are absolutely accurate. Made by Mr. Grozdan. Later, they were modified due to technical problems with winding transformers and adjustment, as well as high demand. I will also say that the over-sensitivity of this circuit introduces additional difficulties when working near high voltages. But of course if you have sensitivity it will also have a large oscillation near magnetic fields. However, this circuit solution, combined with all the laws of nature, is an ingenious creation that remained misunderstood by the audience. I can say all the other metal detectors in comparison are toys for children. There can be no comparison. It will be funny. So the myths and legends are true!

Thanks for the video.

This scheme was created by Stanimir from Varna, Bulgaria and was copied in many places. Now someone is pretending to be great

This is not a stanimir scheme, it looks like it but it is not. First, Grozdanka is a modification of the Fisher detector.
When you look at Fisher's schematics, it has only one. 555.
And it's very close. But wait until I get the photos I ordered sent to me from my archive and you will see that this scheme is wrong. I'm not making this detector for the first time.
And why someone should be better, I share what I know and have done. This is information that can be easily verified.

if fisher 555 clone then we know it like polish 'ALL-1'. is that right?

Yes, in fact, this is the Polish version, but what Mr. Grozdan and later Stanimir are developing is already a very different apparatus. I personally do not know what Grozdan was doing, but apparently he was very well aware of what a magnetic field is and what an electric current is, by introducing polarization into the coil, something completely different happens. And of course there is no other such device. Colleagues can jump as much as they want. But they are very far from the truth.

There is no point in writing lies. The actual depth in the ground depends on the geometry and parameters of the search head. After C-scope and Magnum nothing special was found

Hello, have you seen a clear signal from a ball with a diameter of 3 mm at a depth of 25 cm. I have seen a clear signal that you can't go wrong. Have you seen how the colleague with minelab gp wonders what the signal is and the Grozdanka grower will blow your ears on a coin at a depth of 50 cm. I don't know why you think that with a 26 volt amplitude generator you will have who knows what depth. we are talking about an amplitude of the order of 150-200 volts. have you ever seen a Grozdanka? A real Grozdanka.

The Grozdan detector has a high Q antenna factor. Works well only on soils with little salt.

Don't think that in Fischer and Minelab there are fools and they graze grass.

Yes, i made this detector from 25years ago. So , this is not metal detector !!! This is magnitometer !!! Working like magnitometer !!! And is very sens.

A small correction....

It is necessary to think logically, to work and to make an analysis of the work done. because otherwise you will turn in a circle.

and are absolutely accurate.

Thank you, awaiting for your correct schematic.

Is the program dead?
