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 & 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.
