Sure they lock out. I meant that they are not breathing trimix for 20-30mins with a deco obligation.then how do we get out?
Why are we mixing up submarine escapes with tech diving?

And? I am addressing the assertion that cesa won't work ever from 300 plus.Sure they lock out. I meant that they are not breathing trimix for 20-30mins with a deco obligation.
You are asking two different questions, it seems.From my rEvo diving friends. How much lead does it require if you only have the drysuit? I. E. is the unit on its own negative or positive? The ones I have played with (mini Ti and standard SS) were all noticeably negative on their own.

My comment about "you're definitely going to die" was about hypoxia and DCS from a *CESA* from a 300ft dive.Physics ..and survival
My comment about "you're definitely going to die" was about hypoxia and DCS from a *CESA* from a 300ft dive.
I don't see how a submariner locking out from a 1ata air atmosphere is remotely relevant, but troll away on the pendantics I'm done.
I'm sorry if my post wasn't clear. The question came up about rEvo vs other units in terms of "sinking when flooded" and I replied with my experience, limited as it is. To be clear, I really do like the rEvo, if they made one with a cell validation system like the Poseidon I would dive it in a heartbeat.You are asking two different questions, it seems.
On its own, a rEvo is heavier than pretty much all other units I have ever tried (but I suspect there are other heavy units out there), and since it is very slim and streamlined, it will sink without extra buoyancy source. However, a unit with weights and loop open at the surface, with BCD inflated, will stay there.
Once weighted properly for drysuit diving in cold water (as mentioned in other posts), there is no difference whatsoever with other units. Flood the unit, and you add a fixed volume of liquid, which I believe will be larger on many units, due to the unique rEvo backmounted counterlung design and hose configuration. It will be no harder (and possibly easier) to bring it back to the surface.
If they released the unit, weighted, from the victim with little BCD inflation, and it flooded, yes the unit will likely sink.
The unit itself, without any BCD inflation, is significantly heavier than my Poseidon in the water. In the case of the Poseidon counter lungs, the position of the shoulder t-pieces means that even if I hold the DSV open and above my head, there is a large trapped bubble in the counter lungs. From what I have seen of the rEvo, and indeed my Poseidon with back mounted counter lungs, is that the whole lung will flood in the same circumstance.
To reiterate, this is not a condemnation or criticism of either unit, but an attempt to explain why people say that the rEvo sinks when flooded.
Sorry if the discussion upset you. There is some good info and cross over there, connecting the dots is interesting for some, others prefer to take a position and defend at all costsMy comment about "you're definitely going to die" was about hypoxia and DCS from a *CESA* from a 300ft dive.
