Right.
I like the TF2 though nevertheless, but its RF-detection sucks.
A Cornet is definitely much better at frequencies between 700 MHz and 3 GHz ( but in the Hz and kHz range it is the other way around ).
All meters without decent antennas are to be expected to be very unreliable.
A good picture of it you'll get here ( posted again given this context ) :

The Safe&Sound is too expensive for a crap-meter.
The Gigahertz HF meters will be much more precise and the Cornets will probably give better value for buck than the Safe&Sound.
For 5 GHz wifi and 5 GHz DECT the new RF Explorer 6G COMBO+ ( slim version ) seems a wiser choice.
It has an antenna for both wifi ranges and antennas for 144-900 MHz, additional antennas can be sought and bought.
Just with its telescopic antenna, although designed to measure below 430 MHz, it will probably yield much better results upto 6 GHz than the Safe&Sound, and i expect it to be far superior in the 5 GHz range with its wifi antenna.
But readings will not be that instant, it is an analyser and sweeps over a preferred range which takes more time but provides more data and likely misses less ( but still some and possibly quite some ) signals if you're a bit patient ( and there will likely be some false or "ghost" readings, as in all meters ).
Also it is less easy to use than most EMF-meters.

The near field probes may be useful to test above 1 MHz ( to 7 GHz ) at very close distances :

It is noteworthy that following this info it seems that nearby an EMF source there is also above 1 MHz a distinction to be made between electrical and magnetic fields.
