Key Features
- Single-Button Interface: Effortlessly switch between Air, Nitrox, and Gauge modes with one button—ideal for quick setup and stress-free operation, especially for new divers or those who prefer minimal complexity.
- Wide UFDS Display with User-Friendly Design: The edge-to-edge high-definition screen presents large, clearly separated numerical data with optimized contrast and digit size. Light lines divide information sections, improving readability during dives and in emergency situations.
- Complete Nitrox Management: Adjust FO2 levels from 21% to 50% and set PO2 between 1.2 and 1.6 bar to customize your breathing mix. The CNS oxygen toxicity graphic indicator provides real-time tracking for enhanced safety.
- Advanced Algorithm with RGBM and Deep Stop: Incorporates modern decompression modeling that includes Reduced Gradient Bubble Model (RGBM) and optional deep stops, supporting safer ascents and tailored conservatism levels.
- User-Adjustable Settings: Choose between imperial or metric units and activate the deep stop function to match your dive style and location. Three levels of conservatism let you personalize safety margins.
- Backlit Display with Smart Activation: The screen lights up via button press or automatically when an alarm sounds, ensuring visibility in low-light underwater environments.
- Extended Battery Life & Indicator: Powered by a long-lasting CR2430 button battery, the computer includes a battery saver mode that activates when not in use. A clear battery life indicator and distinct audible alarms keep you informed throughout your dive.
