COPIS v Kiss Classic

GeorgeO

I am an OC diver, tri-mixed certified, that wants to move up to a CCR. I keep my dives 250 feet or less. I am leaning toward a M-CCR for several reasons. If you had to pick either the COPIS or the Kiss Classic, which one would you choose and why. Also, how do I find a COPIS instructor if I choose one? Thanks for your help.

well I would get the COPIS...oh, right I already have one, so Im a bit biased as Im the guy who built the first one. We are running a course at Protec in mexico, January, 07, starting on the 26th and have 3 COPIS students currently. PM me if you would like to join in.

Advantages: Front mounted CL, better all around work of breathing, off board gas addition points, multiple bailout options, major resistance to floods, multiple scrubber options, upgradable to next gen E-ccr at any time.

disadvantages.... some dont like front mounted CL....

Here's another question to answer a question. If you flood the loop on a Meg, you can clear it. Is that possible on the Kiss? I don't know the Kiss, and am a Meg diver as well - That would be a major advantage of the Meg of the Kss if you can't un-flood the loop of the Kiss.... Is there a Kiss diver out there who can respond?

I would also agree with all of Ron's points....

All of these features can be added to the KISS as well

Can you guys explain or post the link on recovering a totally flooded loop on the meg

What is the cost difference? I know th Kiss is significantly cheaper than a normal Meg but how much cheaper is the copis?

scubagrunt

get both!!! they both rock!
kiss and copis are about the same price once you add in cylinders, 3 O2 cells and HP hoses with gauges (6200 or so). depends if you want an uncluttered front or more flood protection and easier off board gas plug in for deeper dives. You are on the right track ask lots of questions.

COPIS pricing is $6159usd complete.

Floods: first, on a meg the dsv leads to the exhale counterlung T-piece, this part connects the breathing hose to the counterlung, there is a diverter in the t-piece that directs any liquid coming from either direction into the counterlung, rather than into the connecting hose, so, in practice, if you remove the dsv from your mouth underwater and fail to close it, water will flow into the hose and hit the T-piece and instead of running into the can, it will be diverted into the counterlung. Now, if you just leave the loop floating over your head, depending on your trim in the water, you will get a bit of water into the counterlung but none over your shoulder into the can, kind of like the s curve in the drain under your sink. At this point we have what we call a partial flood, the diver can replace the dsv, lean slightly forward, press down on the ADV and the flood will be pushed out the OPV, or exhaust valve that is positioned at the bottom of the exhale CL.


If however you tear a major hole in the inhale or exhale hoses and water is allowed to spill down into the can, that flood is not recoverable as long as you cannot repair the hose while underwater. the meg hoses are very tough and I can pick up my meg with the breathing hoses. a flood can also happen if the diver does not follow the predive check properly and fails to tighten down the breathing hose coupler onto the head. One diver (who had not tightened that fitting) had that hose pop off during ascent, flooding the unit. If one could bail to OC, replace that hose coupler, had the water tolerant cis canister in the unit, and worked the water into the exhale CL and vented it, theoretically, one could go back on the loop. The sensors faces are protected by the hydrophobic membrane in the scrubber, so the only way the water can move is back into the exhale CL, not into the inhale side of the rig. The connector side of the sensors would be exposed to the water during the de-watering phase of that exercise, so they shouldnt be trusted past that point. part of meg confined water training is to remove the loop from your mouth, allowing water to fall into the CL, then purge it out. Then we look in the can to find a mostly dry can.

If one does manage to have a leak into the can, the water would have to fill up the entire can, come over the divers shoulder, fill up the entire inhale counterlung before coming down the hose to the dsv and into the mouth, by this time the work of breathing would be quite difficult, signaling the diver to get off the loop.
