Russian electronic apparatus for remote sensing

[Sneshko]

Dear friends!
I've always wondered if our colleagues in Russia have managed to make good devices for remote sensing.
The answer I found in a book called: "Metal detectors for amateurs and professionals," written by our Russian colleagues A. J. Svaulov.
Pictures below:










That the following devices:
- Nonline locator "Oktava-K";
- Nonline locator "Oktava-M", and
- Nonline locator "Oktava-ZM".
These devices produce Russian company "Žučkov", a Russian company sells ABS Systems.
About this in more detail in the next post.

Regards!
