CCR Rebreather Openwater Diving

CCR Rebreather openwater diving is extending bottom times while staying warmer and getting closer to marine life on reefs or wrecks are major factors why divers choose to go on to dive on CCR Rebreathers in recreational diving. Marine photographers have used Closed Circuit Rebreathers for a long time to get closer to their objects, to get better images on either still photography or videography.

Most diving on closed circuit Rebreathers is actually conducted within recreational diving depth and limits. The elevated partial pressure of oxygen or set point which translates into the best possible Nitrox mix during any given dive allows for extended bottom times within non-decompression limits, as well as shorter surface intervals in-between dives.

The CCR Rebreather Diver training comes in a variety of levels ranging from OW CCR Diver (max depth 70 feet / 21 meter) to CCR Diver (max depth 130 feet / 39 meter), Normoxic Trimix CCR (max depth 200 feet / 60 meter), Trimix CCR Diver (max depth 300 feet / 100 meter) and Expedition CCR Trimix Diver (max depth 400 feet / 120 meter).

Technical divers who participate in technical diving due to their diving depth and exposure times are dealing with decompression obligations that need to be addressed. Due to the CCR’s constant Po2 even on ascent allow the diver to benefit from a faster inert gas elemination that at times can bring a 25% decompression time saving over open circuit decompression.

The minimal consumption of breathing gases while using a Closed Circuit Rebreather are economically beneficial. Instead of consuming and releasing large quantities of breathing gas into the atmosphere the breathing gas is recycled. Oxygen is the only gas consumed and needs to be replenished at the metabolic consumption rate.

The all so importand bailout gas, the alternative path to the surface, will be untouched if all goes well and can be re-used again and again.
