The Poseidon Discovery is the world’s first rebreather for recreational divers. It’s a fully-closed, fully-automated unit that will make you see diving in a different light.

At just 18 kilos (39.6 lbs) fully gassed up and ready to dive, the Discovery MkVI weighs less than many dive tanks weigh on their own. And minus tanks and canister, it weighs just 8 kilos (17.6 lbs), making it easy to travel with.
