Homemade miracles – dual-frequency MD Terminator-M and air test (video+)
Homemade metal detectors are very interesting. The functionality is simple, but due to the fact that there is no mass production, two metal detectors from the same garage can be very different from each other.
But will they bring finds? Using the example of a homemade metal detector Terminator-M, you can see the result by air, at least it’s something rather than nothing.
