Designed for the beginner diver, the Aqualung Calypso Regulator (Yoke) is lightweight, easy to travel with, easy to clean, and easy to maintain. Does it get better? Yes, actually, it does.

The first stage is designed with a high-flow, large-diameter piston and is unbalanced. With one high pressure (HP) and 4 medium pressure (MP) ports, your setup is easy and straightforward. Made from marine brass with chrome plating, the body of this first stage stands up to the elements and performs when you need it to. Additionally, the stainless steel spring, sintered bronze conical filter, and EPDM o-rings all work to deliver the air you need consistently. The intuitive design includes a second filter to protect against pollution and the Yoke attachment point helps protect against water retention in this delicate area. Performance and durability with stable pressure out is the key to this first stage. Coupled with an unbalanced second stage, this Calypso regulator uses the mechanism demand valve with a downstream poppet to deliver your air. That Venturi adjustment knob lets you be in control of your air flow, even when you’re wearing bulky dive gloves. With a box bottom, the deflector moves your bubbles out of your field of view. A polyurethane purge cover means this second stage will stand up to the elements and is easily operated with or without gloves. Aqualung’s Comfo-Bite mouthpiece reduces jaw fatigue and is easily switched out with the reusable mouthpiece clip. Rugged, durable, and abrasion resistant, this second stage will stand up to the elements and serve you well. Aqualung Calypso Regulator (Yoke) 1st Stage Features:
