Because of the issues I've been having with my 7SS wrist HR I decided to use my Polar H10 today for the first time. Before pairing the H10 to the watch I replaced the battery and updated the firmware. I ran 9 miles at a steady pace and twice after the 1 hour mark, my HR dropped significantly and stayed low for several mins. Have any other H10 users noticed this? Could this be an issue with the H10 or my 7SS or me? Note, that the strap is pretty new and I religiously clean it after every run.
Usually, when this happens to me, I try:
- Change battery
- Make the band wet (in winter, maybe I don't sweat enough, and there can be drops even mid-run). If that doesn't help, you can try to apply ultrasonic…
I have noticed that when the band starts to be "bad", before the watch start to lose the HR measurements (or produce bogus data), the respiration data disappears. So a good way to "predict" that the band…
I never run outdoors in winter without first smearing gel on the two HRM contact points. If I don't I also have weird signal issues as I don't sweat at all when it gets cold. By the way, it's not actually…
So I ran twice this week using my Polar H10. On Wed afternoon the avg temp on the watch was around 75F and I had no issues with the HR and Respiration dropping. Today I ran early in the morning so the avg temp on the watch was around 64. This time I had a lot of drop outs. What I dont understand is why the drop outs are happening later in my run when I should be sweating more. Perhaps I am not and the water I used to wet the strap dried up? I did buy some conductive gel to see if it improves things. Maybe I should just buy the HRM Pro?
