Ok, I have already asked this questions a few years back without a good answer.
I own 2 Garmin devices (f7x as and epix 2).
Yesterday my 11 year old son wanted to run with one of my watches.
I remembered it screwing up my stats for 4 weeks since he is in much better shape...
So I reset the epix to original mode (full swipe).
He does his run...gets his stats (gps, time, hr...).
Now, to reuse the watch I would have to reset it again and resync it to connect via physio tru up.
Is there a way other than this to lend the watch (different profil like a computer?).
Thanks
