Aqualung Calypso Classic Regulator

First Stage: 

• In-line, high-flow piston design means fewer components, excellent reliability and easy maintenance

• Compatible with EAN 40 new, out of the box

Second Stage: 

• Mid-size, high performance, demand valve second stage
• The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
• Can easily be reversed from right-handed to left-handed configuration by an Authorized Aqua Lung dealer without additional parts
• Comes with Aqua Lungs Comfo-Bite mouthpiece that reduces jaw fatigue
• A grid built into the exhaust tee creates finer exhaust bubbles for less noise and more stability
