The leading developer of underwater breathing technology introduces the Sea LiOn™. One lithium Ion battery can give you enough underwater adventure as nine (9) scuba tanks. Imagine the freedom of not having to fill tanks before your trip, not having to put on tons of heavy scuba gear, and not having to fix gelcoat chips from bouncing scuba gear every year. This is not only the cleanest solution for our environment, but the easiest way for you and your family to explore the new world below the surface. Don’t worry, if you’re already an underwater enthusiast then you know the value of having an easier solution to get out there and dive.​

​With the Sea LiOn™ you can have more freedom to venture into new areas. One unit can take 3 divers to 33 feet for 2-3 hours, and for those shallow water lobster trips it can sustain 4 divers at 15 – 20 feet of depth for up to 2 hours.
