Description
Where the T-Rex 3 Pro is the all-rounder, the Ultra 2 is built for expedition-length days: more battery, more titanium, more map storage and a dedicated trail-running mode with up to 44 hours of tracking. The MIL-STD-810H test report covers heat, cold, shock and humidity.
On the health side, the BioTracker 6.0 sensor measures heart rate, blood oxygen, stress and skin temperature around the clock, with sleep staging, PAI and BioCharge energy tracking in the Zepp app. Zepp OS 5 brings Zepp Flow voice control, Zepp Coach plans and sync with Strava, komoot, TrainingPeaks, Apple Health and Google Fit.
