The draw: Upcoming GoPro integration

Polar’s triathlon-focused offering is a bit older at a little more than three years old, but thanks to near constant firmware updates, it remains fresh. This spring, Polar is rolling out to the V800 the ability to control your GoPro camera, as well as overlay that data onto your GoPro videos. Plus, the V800 is the only triathlon watch these days that supports live heart rate while swimming; others only sync the data afterward.
