MK7 Rebreather Poseidon

Closed circuit rebreathes, now the first choice of diving elite, especially the latest ones with all electronics and advanced hardware and software for safety enable to approach marine life much more closely with minimal disturbance

The near silent or ‘stealth diving’ is ideal for underwater photo and video shoots as you get closer to fish and scientific purposes apart from remarkably extending the duration of underwater stay.

A closed-circuit rebreather weighs just eight kg, including the carbon dioxide scrubber, whereas the normal open circuit scuba weighs about 15kg or more to get the same bottom time.

“The closed-circuit rebreather is so safe and Easy that even children can use it, one of the greatest advantages it offers is substantially enhanced gas efficiency. It is estimated that a standard scuba cylinder contains enough gas to sustain an average resting person for about 60 minutes at the surface and last 30 minutes 10m underwater, and less than 12 minutes at 40m.

“On the other hand, if the same cylinder is filled with oxygen and used to supply a closed-circuit rebreather, the diver could theoretically stay underwater for two days, irrespective of the depth, as the gas would last that long,” In reality, a diver with some a closed-circuit rebreather can stay at a depth of 40m for up to three hours, which is the time taken for the C02 scrubber to get saturated.

Another salient feature is decompression optimization, which is in fact a unique advantage of electronic closed-circuit rebreathers as it maintains a constant partial pressure of oxygen in the breathing gas in contrast to semi-closed rebreathers that maintain a constant amount of oxygen.

“This allows a diver to stay longer at depth without the need for decompression,” Zaki observed. Yet another edge of closed-circuit rebreather is warm, moist gas, allowing body heat to be maintained.

Advanced technology enables the rebreather to constantly monitor the levels of oxygen and carbon dioxide and partial pressure in the loop to calculate bottom time and maximum depth even with multi-level deep dives.

One of the really unit advantage of this unit If at all there is a problem, the system will give visual, audio and vibration alerts allowing the diver to Switch the unit to open-circuit be and   bail out.
