Introducing the world's first and exclusive back-up second stage, the Octopus, featuring a construction of all-titanium metallic components. This design prioritizes both lightweight performance and complete corrosion resistance, making it impervious to the detrimental effects of seawater corrosion. The patented Atomic Aquatics Seat Saving Orifice is a revolutionary feature that prevents wear on the low-pressure seat, extending the service interval and enhancing overall reliability.>These unique attributes make the Ti2 Octopus a dependable emergency breathing apparatus that maintains optimal performance over time. Its compact design includes a low-profile exhaust deflector, allowing easy storage in BCD pockets. The bright yellow flexible front cover ensures high visibility in out-of-air emergencies. Notably, the Ti2 Octopus shares the same second stage as the acclaimed T1 and B2 first and second stage combinations, earning more accolades from the diving press than any other regulator in history.>Setting itself apart, the Ti2 Octopus boasts the world's only depth-activated flow control – the Atomic Aquatics AFC (Automatic Flow Control). This feature automatically adjusts airflow at depth for effortless and natural breathing, eliminating the need for external adjustments. The second stage adopts a balanced linear flow design, ensuring exceptionally easy breathing across all depths and dive conditions. While maintaining simplicity, a rapid adjustment knob is available for rare, specialized situations.
