If it was easy, everybody would be doing it. If this is true, with the AirBuddy, then everybody would be diving. The AirBuddy is a diving support system that does not require refills or heavy equipment. It allows you to dive up to 12m (40ft) for up to 45 minutes and makes diving less of a hassle and more enjoyable.
The AirBuddy consists of a floating dive compressor that follows you around as you dive and a tube for breathing the air from the surface. You can connect 2 divers to 1 AirBuddy or connect 2 AirBuddies together. There's also a couple of safety systems in case of emergencies like a 15L compressed emergency air contained in the red float and an optional redundant egressor.
