Product Information

According to Garmin, the stress level is calculated based on your heart rate variability in a given day. I was a little skeptical at first, but looking through the data changed my mind. I found that on days that had felt particularly harried, my stress score was higher. And on days that felt pretty low-key, I ended up with a low stress score. The device also includes the capability to set an alert if your heart rate goes above or below a certain level. Pulse oximeter

For swimming, I’d agree with Garmin/Suunto/Polar that when it comes to optical HR sensor, that it’s going to be a ‘YMMV’ (Your Mileage May Vary) type of situation. All three companies have said as such in my discussions with them, and it can depend on numerous factors from positioning to the exact swim stroke you’re using. So definitely do a bit of your own testing to see how well things hold up in the water over multiple sessions (both pool and openwater) before you decide if it works for you. This isn’t a Garmin problem, it’s the same for any optical sensor on the market and it’s not going to change anytime soon.Now I’ve crossed out two chunks in yellow. Those are bits where I was stopped on the side of the road not riding, filming something – thus, who knows what funk I was doing then (setting up tripods and such).

Whereas the second one, focused more on the high altitude aspect of things over the course of 7 days, then you can plot PulseOx readings against altitude. You’ll see this in both the widget and online:
