Why buy each?

Fitbit Sense

The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.

6 months Fitbit Premium included

Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.

6-day battery, works with iPhone

Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.

Garmin Forerunner 970

ECG, flashlight, and sapphire lens

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.

Full color TopoActive maps + Triathlon Coach

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.

Running dynamics + Elevate Gen 5

Full biomechanics suite (cadence, vertical oscillation, ground contact time, running power) plus Garmin's most advanced heart rate sensor with skin temperature monitoring.
