Getting close to marine life without bubbles or noise to scare them away is an absolutely wonderful experience. Underwater Oahu provides recreational and technical training and certification for closed-circuit rebreathers (CCR).
How A CCR Works
A CCR uses gas more efficiently than open-circuit scuba systems by circulating the breathing gas around the diver via “the Loop” allowing them to “re-breathe” their gas, instead of exhaling gas straight out into the water as in a traditional “open-circuit” scuba system.
The closed-circuit rebreather system allows you to stay underwater for several hours so you can take your time and enjoy the little (and big) things you will see. During these hours of diving, you will be very comfortable because, unlike open-circuit scuba gear that delivers cold compressed air, a CCR circulates warm, humid gas at ambient pressure (which is just like breathing above surface).
Not Just For Technical Divers
Once used exclusively by technical divers, CCRs are now available for use by recreational divers as well, thanks to the development of Type-R (recreational) closed-circuit rebreather. These CCRs are lightweight, easy-to-transport and have sophisticated electronics to simplify their use.
