Rebreather Diving

RM CCRAs open circuit (SCUBA) divers we rely upon filling our lungs with air from a pressurized gas tank with every inhalation and then exhausting that volume of air into the surrounding water with every exhalation. As we descend deeper the water pressure around us increases and the volume required to fill our lungs increases; in other words, our air supply depletes quicker the deeper we dive.

A rebreather recycles rather than vents the exhaled breath. The exhaled breath passes into a closed loop, where it is pushed through a chemical absorbent (scrubber) to remove the carbon dioxide, and returns through the other side of the loop for the diver to re-breathe, hence the name "closed circuit rebreather" or CCR.

Rebreather diving is more efficent than open circuit diving and some benefits include much easier breathing, no bubbles, warmer and more hydrated.

At Deep Blue Ventures we cater for rebreather divers at all levels and deal in 9 of the most popular units available. We run TDI and PADI CCR courses on the units we service to all levels. We also carry CCR expendables including Sorb/Cannisters and Oxygen Sensors.
