Rebreathers are often seen as a dark and scary side of scuba diving but they’re starting to creep their way into the recreational side and you can even do your PADI Open Water on a rebreather if you like. Normal scuba where you blow bubbles is called Open Circuit or OC because every time you breathe out you lose a lungful of gas. Rebreathers, recirculate that gas and turn it into fresh air, so they’re much more efficient at gas management. Your exhaled gas gets passed through a scrubber to remove the CO2 and sensors analyse the O2 content to top it up. By this method you can breathe the same lungful of gas over and over again until either the scrubber is saturated or you run out of pure oxygen to top it up.
