Poseidon SE7EN+ Rebreather

2021-11-2  All closed circuit rebreathers use oxygen, diluent (air/trimix), a breathing loop, counter-lungs, a mouthpiece to deliver the breathing gas, a scrubber to remove the carbon dioxide from the system and a method to replace the metabolized oxygen. That’s the easy part and where other rebreathers stop but Poseidon SE7EN+ technology really starts!
