Rebreathers used to be only for technical diving, but NOT ANY MORE. Today’s rebreathers are lightweight, easy-to-transport and have sophisticated electronics to simplify their use.
Why dive a rebreather? You get longer no stop limits, reduced gas consumption because you reuse most of your exhaled gas, and unmatched wildlife encounters because you don’t release annoying bubbles.
The rebreather courses train you to rebreather diving to a maximum depth of 100 meters/330 feet (depending on your certification level) and let you experience things you never imagined possible as an open circuit scuba diver.
