Thanks Stefan,

So if I had a Mk 6 and went on a liveaboard, would i need to have available enough pre packed cartridges for the trip, or is there a way of packing myself?

Collin

There is an optional radial scrubber that you can pack yourself.
Stuart has an interview scheduled with them today or tomorrow so more info will be forth coming when that gets uploaded.

Photos coming lunch time Orlando time, keep an eye on the DEMA 2007 gallery. hopefully can get a load of photos uploaded over at the press room

This is a long shot, but are the dimensions of the radial scrubber compatible with the Meg/MKV?

Does it bail-out for you as well?

Almost!
If the HUD turns red, pull it down.
When the HUD is down you will, and the computer as well, be on OC.
When on OC the electronics still will keep the PPO2 in the loop, if you for some resaon goes back to CCR.
If you want coffee after your dive i presume you have to make this yourself. ;-)

If the electronics works I think this is a very big step in the thinking of CCR manufacturing. A couple of months ago there was a rumour that the display showd the PO2 only because it should have been a to big step in the CCR thinking to take away the possibility to "know your PPO2"

All you have to do is turn on the tank valves and dive.
As long as the HUD is green everything is ok, if it´s red, pull it down and go back to surface.
This CCR is NOT for decompresion dives, so it may work.

I asume there should be a big market for alot of uw-photogaphers that have no intrest in going deep.

Actualy I think this is a perfect HUD for any rebreather, Green=Good, Red=Bad, If Red=Take a closer look at you dispalys.

(There is also a "Buddy HUD" on the top of the scrubber)

Two weeks ago when we had a pre peak in Sweden there was no scrubber that you could pack yourself.

Simon on the posiden booth told us there would be a packable radial scrubber for those that wanted that option.

For those of you interessted, there's a Mk VI White Paper to download from the Posedon website:

http://www.poseidon.se/DL_files/MK6_White_Paper.pdf

OceanOpportunity · 3rd November 2007, 16:37

I think the 2-sensor logic makes sense, even moreso after reviewing this white paper. Its effectively akin to us who want more control of our system to have the ability to burst o2 or dil over the sensor face to validate them. this is not a new concept, but automating the concept is. I think this further supports the arguement of many that 2 sensors are suitable for manual controlled units (assuming you have this ability to validate/clear sensors).

...also raises some good points about standardizing voting logic algorithms. Anyone have a matrix put together of how variable they are from system to system? (i.e. what gets voted out and when, sensor averages, etc)

SimonK · 3rd November 2007, 17:09

From the poseidon white paper:

Importantly, however, in the context of the Active Sensor Validation system as used
on no-decompression dives, the introduction of a third sensor causes increased system
complexity (and hence more potential failure modes), without providing any truly
meaningful additional information. Other ASV systems involving additional sensors
and/or solenoid valves have been designed by Poseidon Systems AB (all are in patentpending
stage) and are being developed for use in exploratory rebreather systems for
use in overhead environments (including decompression diving). Discussion of these
more advanced systems is outside the scope of this document.

Roll on the MkVII ??

reading the white Paper I think the 2 cell validation logic makes sens. Mybe we will see something like that also in the rebreathers for deeper dives in the future.

dave t · 3rd November 2007, 17:47

It makes as much sense as a three cell voting logic except the shortcomings in the three cell system are replaced by potential shortcomings in the gas addition systems. My main worry with any fully automated system is when it fails and I guarantee it will fail one day, there is nowhere to go. At least with the systems we have now there are two or three levels of "escape"
The white paper talks a lot about "warning the diver" we all know how good we are at heeding warnings!!!!

I know its aimed at no-deco diving but many a no-deco dives on a ccr can incur a (small) deco penalty if you have to bail onto OC, and a 3l of air will not give much room for hanging about, and as we have seen before rebreather accidents dont just happen to deep deco divers!

I hope I am wrong!
