| Don't know if you are awared or not, but just want to mention that the gas added in SCR units described above by Jonny is not pure O2 (i.e. "oxygen" was written).
In the Rebreather-80 case, it ranges from trimix to nitrox depending on depth. And in the Dolphin case, it is nitrox even though people have used trimix as well.
Lastly, eventhough the KISS was not Jonny's first choice of unit and sounds like was bought only due to economic constraint, it has been mine for the last 3-4 years even though I had other more expensive units laying in the dive room (i.e. MK-15, XCR, BMR-500, etc).
I personally know a lot more people also chose the KISS due to its simplicity instead of the low(er) retail price. I often refer to the KISS as the "Hogarthian CCR"!
IMHO, SCR is a dying technology that will fade away except for specific applications and group of divers. With the advance of sensor and electronic technology, the prices of CCR has been lowered in the last few years from over US$10K to a range of US$4-10K depending on models. And more CCR models are still coming... |
