No Bubbles, No Troubles.

Henry Fleuss designed the first self-contained apparatus in 1876. It consisted of a rubber mask connected to a breathing bag. A copper tank supplied the oxygen and a rope yarn soaked in a solution of caustic potash to scrub carbon dioxide. Ironically, rebreathers today are seen as the latest technology in the diving world, but the truth is rebreathers have been around long before open circuit scuba was attempted.

Rebreather diving is a phenomenal experience that allows divers to enjoy the underwater realm like never before. Whether your interest lies in up-close-and-personal wildlife encounters, amazing photography opportunities or furthering an exploration, rebreathers offer something for everyone.

Today's rebreathers are easy-to-use, yet as more and more brands hit the market, the choices and options can be overwelming. Semi-closed circuit or fully-closed? Electronics-driven or manual? Granular scrubber or cartridge? It can be a minefield that's not easy to navigate.
