• Customizable Nitrox Settings: Adjust FO2 levels from 21% to 50% and PO2 from 1.2 to 1.6 bar to match your gas mix and depth requirements. This precision helps optimize bottom time and safety, especially on repetitive dives.
• CNS Oxygen Toxicity Monitoring: A built-in graphic indicator tracks your central nervous system oxygen exposure, providing real-time feedback to help manage risk during Nitrox dives.
• User-Adjustable Conservatism: Choose from three conservatism levels to align decompression calculations with your experience and comfort. This personalization enhances safety without unnecessary restrictions.
• Deep Stop Function: Adds optional deep stops during ascent to support safer decompression practices, particularly useful for deeper or multi-level dives.
• Audible and Visual Alerts: Critical dive data such as depth, no-decompression limits, and ascent rate trigger clear alarms, ensuring you stay informed even in low-visibility conditions.
• Backlit Display: The illuminated screen ensures readability in dark or murky waters, allowing quick checks without external light sources.
• Dual Connectivity: Transfer dive logs to iOS and Android devices via USB and infrared connection, enabling detailed review and long-term tracking of your underwater activity.

Important Notes

The CR2430 battery should be replaced by an authorized Cressi service center to maintain water resistance and warranty validity. While the device is designed for durability, avoid exposing it to extreme temperatures or chemicals that may degrade materials. Always rinse with fresh water after saltwater use to preserve longevity. Data transfer requires compatible software on iOS or Android devices; ensure your device supports infrared or USB connectivity as needed.
