COPIS v Kiss Classic

GeorgeO

Thank you all for responding. It is great that a community like this provided valuable information and opinions. I know the MEG is easy to travel with, what about the KISS? I also understand that many don't see there is a major issue regarding flooding the KISS, but, what happens if it occurs? Can you recover from it or do you just bail out?

Of course you bail out. Not bailing out is just for alpine divers that would otherwise die for certain .... Why? Sorb needs a few % of water in order to do the work. Soken wet sorb is far less effective in scrubbing CO2 (or we would all dive them continously wet since its easier to keep a Rebreather wet than dry ) CO2 can be described in simple tarzan/jane like terms. CO2 BAD, No CO2 GOOD.

Now I'll wait for the inevitable <---my head as this is an opinion only....

First, the question is, why did it flood?

If it's a mater of the mouth piece falling out of your mouth, then yes the Kiss can be cleared. Water in the exhale hose can be cleared.

The next question is how much of a flood?
The Kiss has a small water trap in the bottom of the scrubber. If you have a small leak, the water can be moved there.
If you have a major leak, then your going to have to bail out (on either unit).

The next question is: Do you own a dive shop in Pennsylvania?

Throw it in your standard hard shell suit case with a coupla T-shirts and boxers & you're good to go! That's true for both SK and CK.

Another option might be the Pelagian, an ECCR that has an adjustable passive add needle valve O2 addition and OTS CLs. It seems like a very sensible design. I seem to remember that it had BOV as standard equipment, so it would be a serious contender if it's really available... -Andy

If I recall correctly, the Pelegian is not an ECCR but a DMCCR (Diver controlled manual CCR).

Paul is right and what people seem to forget is that you may not necessarily find, or even solve, the cause of the full flood and will burn through any diluent you have trying to do so.

This is why I do not have the Cis-Lunar scrubber in my Meg, it is great to have the hydrophobic properties to prevent caustic cocktail, but if you have gotten that far you are well up the swanny anyway.

People need to remember that the hydrophobic properties of the Cis scrubber were designed to allow the scrubber to be changed out underwater.


Proper prepping of a unit, should, in all but a few cases, prevent floods happening.

Cheers,

Dave Cooper.

Yes, ISC will be coming out with their HUD shortly. I am going to be one of the first ones requesting one as soon as they are available.

The KISS range are very transportable, the trick is to ensure you either have or take a tank fixing system that is flexible for your destination.

On the flooding issue, its purely anecdotal evidence but the KISS is actually suprisingly flood tolerant. I know some utter idiot who dunked his mouthpiece into water when he was picking up stages prior to about 2 hours of cave dive. This cretin did the dive on the unit and the only side effect was a craving for coffee after (that damn percolator like noise!). Its not big/clever or a recommendation, merely an observation (before the flame throwers start).

Whilst I'd like a flood recoverable unit, as long as you have sufficient bailout, its not really necessary.

PS. Cant comment on the COPIS, I dont know anyone who'll lend me one <pointed look in Rons direction>

Are there pictures on the Net showing the bottom view of the COPIS lid ? It wasn't in Ron's COPIS article.

I am interested in seeing where the orifice is located in the lid.
