    Poseidon Rebreathers


The world’s most advanced rebreather interface – The Poseidon Se7en contains five separate warning and advisory systems so that you get the information you need to manage your dive without the task-loading normally associated with rebreathers. The main Poseidon Se7en data interface is a large format flat screen panel that displays all you need to know about consumables management – cylinder pressures, dive time, depth, oxygen level, and it incorporates a sophisticated resource algorithm that monitors all systems for you and tells you when its time to head up. If things are not going correctly for whatever reason, the Poseidon Se7en has audible, tactile, and visual warning systems to get your attention, and to advise your diving partner of your status.

Congratulations on your decision to learn to dive the Poseidon Se7en Closed-Circuit Rebreather (CCR). The Poseidon Se7en design includes several fundamental improve- ments over previous closed-circuit rebreather designs.

The Poseidon Se7en Rebreather is a fully closed-circuit, automated rebreather (eCCR) that will allow you to have a very different and improved diving experience. The Se7en is exceptionally small, light and simple to use. With an unmatched degree of automation, the diver is better able to enjoy the dive. Designed, built and tested to perform in all conditions, the POSEIDON SE7EN is the next generation rebreather. Performance and ease of use are combined to enable divers of all abilities to experience the underwater world without compromise. Whether you want to get closer to marine life, spend much more time underwater, dive deeper or simply enjoy the bubble-free silence, the POSEIDON SE7EN is a different way to dive. Everything in the Poseidon Se7en is made with simplicity and safety in mind.

The Design – Rebreather diving made easy

Extreme compactness – at only 18 kg ”ready to dive” and 9 kg “travel weight” the Poseidon MKVI / Se7en Rebreather is one of the world’s smallest rebreathers. Take it as carry-on baggage when flying. Enjoy the freedom. Yet it is not “lightweight” in terms of performance – you get three depth-independent hours of near-silent diving. True plug-and-play carbon dioxide absorbent cartridges. Simple and fast to use. Pre-packed axial cartridges of SofnoDive® 797 absorbent give you 3 hours minimum diving range and can be changed-out and replaced in seconds. Switchable mouthpiece – in a significant new patented design, the Poseidon Rebreather gives you the ability to switch from closed-circuit to open-circuit operation in one easy motion, without the need to search for a spare mouthpiece in an emergency. The ultra-compact switchable mouthpiece is lightweight and easy to breathe, giving you high performance in both open-circuit and closed-circuit modes. The Poseidon Rebreather mouthpiece also combines in the same housing a pressure balanced “Automatic Diluent Addition Valve” (ADV) that compensates for breathing volume in closed-circuit mode, so that you will never run short of a full breath during a dive. Easy maintenance – the entire rebreather breaks down rapidly for washing, drying, and storage. No tools needed.

The Electronics

The first truly auto-calibrating and auto-validating rebreather. The Poseidon Rebreather uses a patented automated method to verify that the oxygen sensors are working properly at all times – both before and during a dive. An intelligent battery – it’s your personal power and data storage system. Plug it in and the system knows it’s you, as well as your dive history, including repetitive dive information. Remove the modular battery, put it in your shirt pocket, and take it home to recharge it. When you are ready to dive, take the battery from the charger and plug it into the rebreather. New software releases can be downloaded and installed over the internet, and various system parameters can be customized to meet your particular dive operating paradigm.

  • Scuba

    Any self-contained underwater life support system. The term “scuba” originated as the acronym SCUBA for “self-contained underwater breathing apparatus”. However “scuba” is now considered a word, not an acronym, and writing it in capital letters is incorrect. People sometimes refer to open-circuit equipment as “scuba,” but this also isn’t correct because rebreathers are scuba, too. In fact the first scuba was a rebreather (Henry Fleuss, 1879), not open circuit.
  • scr

    Semi-closed Circuit Rebreather; scuba that recycles a portion of exhaled gas. Bubbles escape in small bursts or streams, but far less than with open-circuit scuba
  • rebreather

    Scuba that recirculates some or all exhaled gas; terms includes both CCRs and SCRs.
  • ccr

    Closed-Circuit Rebreather; scuba that recycles all exhaled gas.
