I am getting very weird HR readings both from normal Run activities as well as Swim activities.
So what I'm experiencing is that the HR is much lower than it should be compared to all activities I've done since I got this watch (955 Solar) in the summer of 2022, and compared to how I feel.
It started with 14.13 where I was going out for a normal 5km run but the HR suddenly started to go down after about 1:30, instead of go up, and then after roughly 4:30 it dropped like a rock to 60. When this happened I watched it closely while running and it just sat there, in the low 70-80 and after about 7:30 I stopped the run because I thought the watch was bad.
Here's what it looked like:
Then I checked the forums and at the time some people was experiencing similar HR reading problems. After 7:30 my HR should be somewhere around 160 for me, so I understood that something fish was going on.
Here's an example of a swim activity with Firmware 13.22 back in November, 612 meters in a 12m pool at around 28 C temperature, and 148 HR average and 83% in Swim HR Zone 4:
Here's the same activity today with Firmware 14.15, same pool and same length, same temperature. Even with a slightly faster pace than the one above, now it says the HR average is 113 and 86% in Swim HR Zone 2. What??
Is this getting a fix soon? Q2 is over and I’m done with an expensive *** 955. Thank you
