POSEIDON SE7EN - The Next Generation Rebreather 

From the moment you turn on your Poseidon SE7EN, you’ll notice the difference. Automated pre-dive safety checks take 3 minutes, rather than 30 minutes or more on other rebreathers. In the water, your SE7EN’s patented, on board computers pro-actively monitor and manage all aspects of your dive, enabling you to focus on what’s important; the amazing undersea world you’re exploring and the goals you’ve set yourself for that dive.

Weighing in at just 11 kg / 23 lbs without cylinders, your SE7EN is an easy travel companion that will open up a world of dives beyond your imagination. Stylish, rugged good looks will let fellow divers know that an adventurer is among them.

Versatility is everything. Whether you’re on a gentle dive on a tropical reef or a challenging, deep wreck dive, Versatile Performance Technology© makes your Poseidon SE7EN the perfect companion, equally at home in all environments. Other rebreathers are described as “recreational” or “technical”, putting artificial limits on your diving experiences. Capable of whatever dive you want to do, the Poseidon SE7EN is the only rebreather you’ll ever need.

Developed from the world’s first recreational rebreather, the legendary Poseidon MKVI, the POSEIDON SE7EN gives you 7 Next Generation Benefits: 
G7 Inside 
Generation 7 electronics open up endless possibilities for interaction, accessories and apps. Entirely new internal hardware driven by a new generation of firmware makes the SE7EN faster, flexible and reliable in any diving environment. 
Bluetooth Connectivity 
Download your dive logs in seconds, update your settings and interact effortlessly with your POSEIDON SE7EN, all using Bluetooth 
Dive Management System 
Enjoy enhanced interaction with your rebreather. The upgraded configuration tool interacts with your POSEIDON SE7EN via Bluetooth, allowing you to make configuration changes in moments. See your dive logs in far greater detail and much more. Better still, it’s now Mac compatible! 
Recreational or 100M Technical Rebreather 
The POSEIDON SE7EN can be whatever you want it to be! You can use the SE7EN as a Recreational Rebreather or as a 100M-rated Technical Rebreather; it’s your choice! Poseidon’s industry-leading upgrades give you the ultimate recreational and technical rebreather flexibility 
Enhanced Service & Support 
Poseidon already has class-leading reliability and technical support, but the POSEIDON SE7EN makes service and support even easier and more convenient. Automatic dive log downloads to support via Bluetooth, combined with detachable displays and sensors mean that support is even faster and more convenient than before! 
Upgraded Mouthpiece 
The best rebreather mouthpiece just got even better! A new system keeps the bail-out valve locked in place in closed or open circuit, while still enabling simple switches from closed to open circuit 
Protective, desirable and functional in equal measures, the cover on the Poseidon SE7EN has a built-in handle and trim weight system, along with grab and lighting rails. 
In a world full of compromise, we escape by visiting the one place that doesn’t: the ocean. Yet when we get there, we are forced to compromise. Not any more… 
Designed, built and tested to perform in all conditions, the POSEIDON SE7EN is the next generation rebreather. Safety, performance, ease of use and desirability 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 the smartest, fastest, safest way to dive. 
The POSEIDON SE7EN – one day, all rebreathers will be like it.
