When you follow this video: pay extremely good attention to the polarity of the battery tube ! (no idea how he/she distinguishes between + and - in the video)
I also have my doubts about a polarization protection diode in parallel with the battery, instead of a diode in series. Of course there is the 0.6V drop, but the detector works fine with 3.9V instead of 4.5V.
Especially for a military type of detector, I would assume it is more robust to any abuse than any other device ?
