Aqualung Octopus Calypso / Titan

Second Stage

Venturi Adjustment Switch
The Venturi Adjustment Switch allows divers to precisely control and adjust airflow. In the “MIN” position, valve assistance is minimized, resulting in higher inhalation effort, ideal for preventing freeflow. In the “MAX” position, valve assistance is maximized, providing lower inhalation effort. The overmolded elastomer and ergonomically designed lever allow easy airflow control, even while wearing gloves.

Polyurethane Purge Cover
A rugged and durable polyurethane purge cover that is abrasion- and tear-resistant. It minimizes inhalation effort, allows easy water purging, and helps protect against impacts.

ComfoBite
A patented, comfortable mouthpiece featuring a unique palate bridge that reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone, it is both soft and durable.

Interchangeable Mouthpiece
The detachable and reusable mouthpiece clamp allows quick and simple tool-free replacement, reducing plastic waste.

Reusable Mouthpiece Clip
Enables fast and easy mouthpiece changes using a removable, reusable clip.

Side Openings
Prevent freeflow when diving into currents or riding an underwater scooter.

Simple Maintenance
Achieved through a reduced number of components and easy access to the exhaust valve via a clipped deflector.

Deflectors
Split bubbles to reduce noise and protect the valve during exhalation.

Hose and Front Cover
Includes a 1 m yellow hose and yellow front cover for easy identification in emergency situations.
