The pick
Polar H10 Heart Rate Monitor Chest Strap
Why choose it
The accuracy reference, worn on the chest.
The Polar H10 is what people mean when they say wrist trackers are not accurate enough. It is a chest strap, not a watch, and that is precisely the point: worn against the sternum, it captures heart rate with a fidelity optical wrist sensors cannot match. If you train seriously and want data you can trust, this is the reference.
