I love this regulator. Very simple, but quite elegant. Great response in shallow and deep dives. Functions like the higher priced regulators. I really like the way it looks too. Highly recommend.

Questions and Answers for Aqua Lung Calypso Regulator:

  • earl:

    Is this first stage balanced?

    Bill  (Certified Scuba Instructor at

    No this is a standard 1st stage not a balanced unit.

Aqua Lung is proud to introduce the fifth generation of the popular Calypso regulator. This simple design, with its attractive price, makes it a popular choice for dive lockers as well as new divers. It is compact, lightweight, easy to service and it breathes like a regulator that costs much, much more.

For those in colder climes, you’ll be glad to know that this work horse regulator is coldwater compatible having surpassed the CE norms for cold water.

The orange color accents makes it a logical choice for Aqua Lung Partner Centers to coordinate with the Wave BC.

First Stage:
In-line, high-flow piston design means fewer components, excellent reliability and easy maintenance
Large diameter of piston guarantees a more stable medium pressure output
The 6 large holes in the end cap results in easier cleaning as well as better thermal exchange, thus improving the freezing resistance
Features 1 HP port and 4 MP ports
Compatible up to 40% O2 when new, out of the box
Second Stage:
New, mid-size, high performance, demand valve second stage
Easy-to-grip venturi knob stops unwanted freeflow when the regulator is out of your mouth
Can easily be reversed from right-handed to left-handed configuration by an authorized Aqua Lung dealer without additional parts
Comes with Aqua Lung’s Comfo-bite mouthpiece which reduces jaw fatigue
A grid built into the exhaust tee creates finer exhaust bubbles for less noise and more stability
All new, easy purge front cover
A new, reinforced polycarbonate material makes this second stage stronger than its predecessor
The side openings on the front cover prevent freeflow when facing into currents or riding a scooter

Available for shipment to U.S. zip codes only
