I had an issue at a half marathon 3 weeks ago where my watch picked up 3 people's HR readings during the beginning and ignored my external armband HR monitor (Scosche, the very best) which really screwed up some of my race. I lean heavily on HR data.
Anyways, I wanted to ask this here because I can't find concrete answers elsewhere. Do I need to ADD this particular HR monitor to my watch and the day of the marathon, it'll sync onto mine and stay that way? I did add it to my watch a week ago, gave it a name, and then the other day I used it but it connected as a generic factory name. So yeah, that didn't work great.
What to do to guarantee it sticks with mine and not anyone elses? (and no, relying on the OHR at this point is not a possibility. while it has improved for me it still glitches too much and locks onto cadence lock from time to time).
