Hill Splitter™ automatically detects and analyzes each climb during your activity, providing detailed metrics like: elevation gain per climb, average grade, and time spent ascending. This helps trail runners and hikers better understand their performance on varied terrain.
The watch meets MIL-STD-810G standards, meaning it’s tested against: extreme temperatures (-20°C to +55°C), humidity, shock, and water immersion (up to 100m). The sapphire glass face resists scratches, while the stainless steel bezel withstands impacts.
In our tests, the Grit X Pro maintained ±5m accuracy in open terrain and ±8m in dense forest. It uses GPS+GLONASS+Galileo+QZSS satellite systems and features “FusedTrack” which combines GPS with motion sensor data when signal is weak.
No, the Grit X Pro focuses on core outdoor and training features without music storage. However, you can control music playback on your phone and receive notifications when connected via Bluetooth.
