The Aqualung Calypso/Titan Octopus is a reliable and easy-breathing second stage regulator designed to complement the Calypso and Titan first stage regulators. Ideal for both beginner divers and dive centers, it offers durability, compactness, and comfort. Its high-visibility yellow hose ensures quick identification in emergency situations, enhancing safety during dives.
- Venturi Adjustment Switch: Allows precise control of airflow. In the "MIN" position, it minimizes valve assistance for higher inhalation effort, ideal to prevent freeflow. In the "MAX" position, it maximizes valve assistance for lower inhalation effort. The ergonomic lever, made of overmolded elastomer, facilitates adjustments even while wearing gloves.
- Polyurethane Purge Cover: Durable and abrasion-resistant, this cover minimizes inhalation effort, allows easy water purging, and protects against shocks.
- Comfo-Bite Mouthpiece: 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 sturdy.
- Interchangeable Mouthpiece: The detachable and reusable mouthpiece clamp allows for quick and simple tool-free changes, reducing plastic waste.
- Side Openings: Prevent freeflow when facing into currents or using an underwater scooter.
- Simple Maintenance: Achieved through a reduced number of components and easy access to the exhaust valve via a clipped deflector.
- Deflectors: Break up bubbles to decrease noise and protect the valve during exhalation.
