The Poseidon Mark SE7EN CCR (Closed-Circuit Rebreather) is truly the world’s first CCR for recreational diving. It is designed, built and tested to perform well in all conditions. It’s a fully closed, fully-automated unit that will make you see diving in a different light. Performance and ease of use offer divers the opportunity to experience the underwater world without compromise.

Whether your desire is to get closer to marine life, spend more time underwater, dive deeper or simply enjoy the bubble-free silence, the Poseidon Mark SE7EN is for you. Together, the on-board computer and Smart Battery monitor and log both your oxygen exposure and decompression obligation.

The Poseidon Mark SE7EN can be whatever you want it to be — a Recreational Rebreather or a 100-meter-rated Technical Rebreather; it’s your choice! With time and training, the ocean floor can be your limit.
