I am not sure about the need for two scrubbers for air DIL dives. I have taken my unit to 50m way too many times and never had any signs of hypercapnia.


Warm Water.


These WILL break thru in cold water with one scrubber and a diver HARD at work. Light swimming in warm water they will 'probably' be OK.

The thing is this:

IF you carry a bailout bottle,

AND you want to live long enough to die of old age,

WHY NOT use the offboard bottle for the diluent source and keep two scrubbers? I mean, what's the down side to this? None? There's your answer.

But WHEN you want to dive the thing shallow (like 10 metres) without offboard bailout why not just remove one scrubber and add the internal cylinder for internal diluent?


Make it able to be used either way and it'll be perfect.


The square scrubber does have twice the dwell time of the gas on the 'sorb.
