Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.

The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
The FR970 is the first Forerunner with ECG and a built-in LED flashlight — plus a sapphire crystal lens and titanium DLC case for durability that rivals the Fenix 8.
Turn-by-turn navigation on preloaded worldwide TopoActive maps, combined with AI-powered Garmin Triathlon Coach structured training plans — a premium combination at any price.
Full biomechanics suite (cadence, vertical oscillation, ground contact time, running power) plus Garmin's most advanced heart rate sensor with skin temperature monitoring.
