the 5g esmog spion is not yet available, but soon we could try it out.
the old esmog spion picks up 50 Hz very well and frequencies in the kHz range certainly too.
no meter will detect all and everything within their specifications, a lot of signals will go unnoticed.
when confronted with a mixture of emfs ( pretty normal outside of testing labs ), the performance gets even much worse.
i think that the esmog spion is not that accurate but misses less important signals than average.
the clear sound output is valuable as it helps to distinguish between different signals.
i've never heard of that 3 wavelengths rule, but at higher frequencies it certainly seem to apply to some extent.
below 1 MHz i guess there is no need to worry about this, the question is also how to define the word "accurate".
