Accelerated decompression: Breathing the best mix at every depth makes decompression stops much shorter, allowing you to get out of the water faster.Unlike open circuit regulators, depth has no impact on gas consumed by a diver. Extremely gas efficient: perform deeper and longer dives with minimum cost (especially for those using trimix).But there are a few disadvantages as well. The advantages of diving on a closed-circuit rebreather are enormous. It’s also essential to ask yourself what type of diving you’ll use it for and will it satisfy your needs? Choosing a reliable, durable, and reasonably easy to maintain unit with affordable spare parts will save you some cash in the long run. Maintenance is much more complicated on CCR than open-circuit regulators.Plugins offer you the possibility to plug in your off-board gas during the dive.Manual add valve allows you to control how much oxygen you are adding into the breathing loop while running it on or off-board.Reliable electronics monitoring PPO2 and dive parameters are vital for a rebreather as these provide essential information and control the PPO2.

Scrubber duration and size will be the primary limiting factor of your dive time.

Depending on the position, they will affect the work of breathing. Counter lungs are flexible bags that allow gas to be stored around the unit.Before we start, let’s run through some of the important components to look at when choosing a CCR:
