Potentially stupid question

[ootini]

Hi, I'm still reading bits of guff here and there on various CCRs and I've recently been reading a few bits about the new Poseidon MKVI. I noticed this on the website :

Poseidon’s MKVI has 5 big advantages over traditional open circuit equipment: 3 hours typical dive time, Safer and easier to use, Lighter and smaller, No decompressions stops and Silent operation makes you part of the environment; not just a visitor.
The MKVI, the first true technological breakthrough in decades, is a game*changer.

Exactly what do they mean by "No decompressions stops". I get the idea that by keeping the PPO2 as high as possible they increase the time at depth before stops are mandatory, but does this mean the unit is not designed for deco diving? I apologise if I've missed something completely but it seems odd to design a CCR for ndl diving only.

Yup type R - recreational ie no deco

Hmmmmmm I was under the impression it was R-ish, as in it took away some of the comlications of more "techie" CCRs but would still allow for "proper diving" if you wanted too, hence the Trimix battery option? Non?

Well fcuk my old boots, from the manual :

In the lower center of the Alarm Signal Area is
the Decompression Ceiling Alert. This symbol
will flash when the diver has incurred a decompression obligation. The Poseidon MKVI is not
intended for decompression diving, so the dive
should be terminated whenever this icon is displayed. The diver should ascend towards the
surface at a slow and controlled rate, watching
the Primary Display for the Stop Alert and additional decompression information (see below)

What's the bloody point in that then?

Poseidon crossed off the list I believe.

Dave, depends on what you want the CCR for. Recreational CCR are not for what people traditionally consider CCRs are for. E.g. Deep, long dives, but rather warm gas, no bubbles, long NDLs in shallow depths where gas might be the limiting factor for OC.

The techie version is on its way shortly.

I get what you mean Gloc, but seems to me that "allowing" the unit to go into Deco would have a been a wise move on Poseidons part. By simply "nerfing" the whole unit not to allow decompression at all seems quite restrictive.

Again, depends on who your user is. To go into deco means you have to have redundancy, easy way out is to say 'No deco'. Depending on depth, majority of people will get bored before hitting NDLs as recreational divers.

They have deco versions with the blue battery as alluded earlier.

So simply by switching the battery out the unit goes from Rec to Tech? And the electronics now allow proper decompression etc?

[GLOC]

Yes
