The Course

This is an exciting course, to enjoy the thrill of bubble free diving and to enroll in the PADI Rebreather Diver course.

Do you think rebreathers are just for technical diving? Think again because the latest rebreathers are lightweight, easy-transportable units that use sophisticated electronics to simplify their use.


Long dive times: The biggest advantage of a rebreather is gas efficiency. A single fill of a small gas cylinder or cylinders and CO2 scrubber can last for anywhere from one to three hours, depending on which rebreather it is. Unlike open-circuit scuba, your gas duration on a rebreather is nearly independent of depth, so you could, in theory, spend all that time on the bottom.

Silence. Rebreathers exhaust few or no bubbles. You don't hear that roar of exhaust bubbles, and neither do the fish. That allows you to get closer to marine life, which is why rebreathers are popular with professional photographers and some researchers.

Warm, moist breathing gas. The chemical reaction in the CO2 scrubber actually warms and humidifies your breathing gas. Diving with a rebreather does not give you that cotton-mouth feeling and doesn't chill you as much.

Optimum gas mixture. The more sophisticated rebreathers constantly monitor the partial pressure of oxygen in your breathing mix. They can keep your PPO2 constant regardless of depth or exertion, or alter it on the fly for needs like decompression. The benefit can be less nitrogen uptake and faster offgassing--in other words, more bottom time with less DCS risk.
