Garmin watches are notoriously inaccurate for HR measurements unless it's walking/running/biking. That was the main reason I ditched it and went with Apple Watch where the HR accuracy is miles ahead. Yes, You will not get fancy garmin metrics but what is the point of them if they're based off inaccurate readings.
I have an Apple watch 6. I've been a bit nervous to wear it winging. Do they have a decent waterproof rating? Are there any useful apps you use for winging?
As I'm new to winging, my heart rate feels like it's through the roof when trying to pump up onto foil in marginal winds. After a few fruitless attempts to get up, I have to sit on my board for a few minutes to recover. I'm sure this will get easier as my wing pumping gets more efficient, but for now, I'm loving 18-23kts and my Forward Wip harness belt
