Hi Daniel,
I have a Garmin Edge 530 and a Vivoactive 3 (watch) that I was using as heart rate monitor while riding and I wear all day so it tracks everything else (steps, calories, sleep, etc...)
I'm not big on looking at data (and not really good at training) so I can't really talk about that.
The paring with the Edge device always worked well, even though you manually need to start it at the beginning of the ride, I would say it works well enough but it has two downsides:
- once you activate the heart monitor function your watch only shows your BPM and doesn't do anything else (text messages, notifications, ...)
- sometimes the registered rate was lower that I believe it was, especially if riding mtb/gravel, I suspect that has to do with either the wrist position or the watch bouncing around
I now switched to a proper
heart rate monitor mostly so that I use my watch as a regular smart watch while I ride...
