The T-Rex Ultra 2 utilizes a dual-band GPS system supported by six satellite positioning systems and a circularly polarized GPS antenna for stable signal reception in canyons or urban environments. Users can access a variety of mapping tools directly on the wrist:

• Preloaded Base Maps: Full-color maps available offline.

• Route Management: Save up to 100 routes with turn-by-turn navigation and automatic rerouting.
• Point-of-Interest (POI): Search and navigate to specific locations without a phone connection.
• Real-time Alerts: Altitude monitoring, barometric pressure changes, and storm warnings to keep you safe in changing weather.

Professional Diving Capabilities

Unlike standard fitness watches, the T-Rex Ultra 2 is certified for recreational scuba diving and freediving. It supports water resistance up to 10 ATM and enables freediving up to 45 meters. The software includes specialized diving screens that track depth, duration, and safety intervals. The physical hardware is tested for high-pressure environments, making it a viable tool for marine enthusiasts.

Health and Fitness Tracking

The device is powered by the BioTracker 6.0 PPG biometric sensor, which features a 5PD + 2LED configuration for improved data accuracy during vigorous movement. It offers 24-hour monitoring of heart rate, blood oxygen (SpO₂), and stress levels. Fitness enthusiasts can track 187 different sports modes, including 25 strength-training movements and 8 sports types that are recognized automatically.

Post-workout analysis provides data on VO₂ Max, Training Load, Training Effect, and Lactate Threshold. For recovery, the watch tracks sleep stages, HRV (Heart Rate Variability), and skin temperature, helping users understand when their body is ready for the next session.
