Ask an Aquanaut: Rebreathers
Ron Peters asks: Just noticed three of your divers exiting the habitat. What rebreathers are they using. Are they CCR? Why did you select these particular units?
Dear Ron,
The rebreather is the Inspiration with the vision electronics.
Yes, it’s a closed circuit rebreather (CCR)
We chose the Inspiration mainly because the company, Ambient Pressure Diving (APD) was confident it could modify the existing “on board” computer and software to calibrate during saturation. The modification also allows us to turn the computer off during saturation. All dive computers do not allow a diver to turn it off during a dive… i.e. saturation.
There were other reasons too, like the canister duration and the ability to see how much CO2 absorbent was being consumed so to speak, due to it’s temperature stick inside the CO2 canister…
