are you really sure about that, malcolm?
the coded tansmission is not featured in the manual or elsewhere.
the heart rate receiver in the watch seems to be very sensitive, as it also detects non coded "heart rate noise" by electrosmog around.
so far the
x6hr works better (less artefacts, more sensitive) than the Polar S810 I previously owned.
It would be good news if the
X6HR transmission would be coded, but I doubt it....
Could you add some information (source?) ?
Thanks
