Questions & Answers

Shopper : i am a commercial sea urchin diver and love this set up..  my question is where can i get a new filter? whats the model number of the first stagedarrick c : Hello, those filter only come in the service kits. If you need it replaced, then you would need to take your rig in for service.
Paul W : is this a balanced regulator ?Mario C : No its not
Shopper : does this come with a hose?HOLLY C : Yes it does.
bruno p : Is this the 2017 version of the Aqua Lung Calypso? There is no photo in the add. Kind rgdsMark H : Yes, this is the current model.
Shopper : What is the temperature range for this regulator?RUBEN R : I have used the Aqualung Calypso regulator to temperature between 65 and 55 without any issues. It seems that low temperature will not affect its working mechanism at the first stage. It continues to supply air as in 78 degree waters without freezing any internal parts or changing flow pressure while breathing. It does the work! I will recommend this regulator to any of my customers.ARIANNA D : I used this regulator in Croatia this summer in water that was about 14 degrees Celsius, and in Sri Lanka last summer, in about 29 degrees Celsius, or 57-80 degrees Fahrenheit and it worked beautifully. The sites were also very different in terms of depth: Sri Lanka was 110 feet and Croatia was 10 feet, and there was a lot more sediment in Croatia. I think it's a really solid regulator and would definitely recommend it. I would also recommend the Cressi XS Compact MC9 regulator which I preferred only because of its smaller profile.YAN G : Above 50 degrees F.

Love the Reg.

Used this on 5 dives and the reg. did an excellent job. Took it down to 55ft, bottom temp. 54, with no problems. Breath easily from it and no jaw fatigue. I have recommend this reg. to other divers. Great piece of scuba equipment!

Great reg!

I love the simplicity of this Calypso and the twin octo for it. It breathes just as well as many balanced regs do. I've been down to 115' with this setup and have NEVER had the slightest problem! I'm a fan of having your regulator tell you when your tank pressure is getting down so you can look at your SPG and soon end your dive. The price of this regulator is great, too! Call me old school, but that's what we used and how we used scuba gear in the 1970's and it worked great!

Strong Regulator

I am very pleased with my purchase. I use it as my reg. on my pony bottle, a Faber 23 csf hp steel tank. I usually end my last dive by using my pony for my safety stop. The Aqualung Calypso breathes as easily as my Atomic main reg.

Excellent quality at a terrific price!

I am completely satisfied with this regulator and purchase. Lightweight and comfortable regulator that delivers plenty of air and effortless breathing. I used it recently for an hour long dive in 42 degree water with no issues whatsoever. Good work Aqualung!

Failsafe and Consistent

I still have my Aqualung Calypso regulator from 20 years ago. I have changed the hoses and O-rings, and it still operates as new. I have put my life in the hands of Aqualung products for over 20 years of diving, and have never, NEVER been disappointed. Very good, high-quality regulator, for beginnger to advanced usage. Jaque Cousteau founded this company, and for good reason; they are sturdy, dependable, and failsafe products.

Incredible bargain!

I have dove this regulator down to 115 feet in 65 degree water and it works great. Breathes easy and is adjustable at the 2nd stage. It is light weight and comfortable. I have always liked AquaLung products, and this is a great value at a very affordable price.

Great Reg... Especially for the Money

Great regulator. I was accustomed to using a Scubapro Mk25/S600 and this regulator is not quite as smooth as that... but this one is also almost [$] cheaper. It's very well made, and it does the job. I'd say the most noticeable difference is the added breathing resistance at depth. If you're new to diving, this one is all you need. If you go every weekend, then you might want to go for something flashier. If I needed a backup reg, I wouldn't even think twice about getting this one.

Great Value!

I'm on the dive rescue team for the fire department that I work for. We use these regulators (enviornmental seal added aftermarket) for our rescue divers. These regs get over 250 dives on them each year and are abused bouncing around in the fire engine and function with out any problems. They are also inexpensive to rebuild as they're everywhere. I liked them so much that the last time I needed regulators for my personal use, I chose to not go with the Dive Rite and did this instead. I use them on my stage bottles and would dive them any time as my main regulators.

For over 70 years, Aqualung has been at the forefront of scuba regulator innovation. Aqualung regulators offer comfort, ease of breathing, control, and peak performance for all types of divers. The Calypso regulator is a dependable favorite, and its refreshed design makes it attractive and affordable. Its high-flow non-balanced flow-by piston technology ensures reliability and high performance in even the most demanding conditions. The large diameter piston provides a more stable medium pressure output, while large holes in end caps improve thermal exchange and resistance to freezing.

The Calypso is lightweight, compact, and easy to maintain, making it an ideal choice for beginner divers and dive centers. Dive centers will appreciate its compatibility with previous versions and the numbered sticker that helps identify the regulator for renting and tracking purposes. The regulator is made from chromed marine grade brass and has four low-pressure and one high-pressure outlet. The downstream demand valve ABS housing second stage regulator is Nitrox compatible with up to 40% oxygen out-of-the-box, and it comes with an owner's manual.

The Comfo-Bite mouthpiece with a patented roof of mouth bridge reduces jaw fatigue, and the removable and reusable clip facilitates quick and easy mouthpiece changes. Maintenance is easy with few components and easy access to the exhaust valve through a clipped deflector. The in-line Venturi knob offers effective and progressive adjustments using an ergonomic design for easy manipulation, even with gloves. The polyurethane purge cover is abrasion- and tear-resistant protects from shocks, allows for easy water purging, and decreases inhalation effort. Side openings prevent free flow when facing currents or riding a scooter, and the reinforced polycarbonate second stage is stronger. The Deflector splits up bubbles to decrease noise and protect the valve from expiration.

In summary, the Aqualung Calypso regulator is a reliable, robust, and affordable choice for beginner divers and dive centers. Its lightweight, compact, and easy-to-maintain design provides excellent performance in a variety of diving conditions.
