I guess this belongs here for now, or in the KISS forum, or in new products later!

I could be wrong, but the way that I read it is...

It is not like the HH or Shearwater package which convert a mCCR to a ECCR. It has a solenoid and (sounds like) a fixed SP or something less than 1.0 (0.4 or 0.7 for example ?) so if/when the diver is distracted, the "parachute" will prevent the loop from going into hypoxic state.

Now, if that's true, and if there is enough of requests, I don't see a big problem making the set-point to be user-changeable to make the unit into a full-fledge ECCR... if the manufacturer wants to do it...

Just been through the spec sheets. Max depth of the MicroDOT is 85m. thats a bit naff... Its fine if this is aimed at the recreational market but its no good for the tech divers.

I noticed this too...

It's seems odd to me, it *could* be a really neat product, and certianly looks well made but it misses a couple of essential features.

The ability to turn it into an eCCR if that what you want, and a decent depth rating.

Cheers

Huhm... I believe the max depth is because of the uncompensated O2 reg feeding into the solenoid.

I am sure if you increase the IP to max, you should be able to get it to work down to 115m. Or simpler yet, carry a second O2 tank with a compensated reg feeding only to the solenoid and get unlimited depth.

Yes, agreed regarding the IP, but this is the microdot I am referring to. the electronic housing is only rated to 85m. If you look at the microdot page, not the dive drive one you can see it in the spec page.

I also notice the tachyon dive computer, while it appears to be in the same housing but a different colour, is rated to 150m. I am guessing the 85m is probably due to the gland in use.

Got you. It might be the gland as you said...

While certainly useful for extra peace of mind, I would personally re-think the combination me, myself and the rebreather if that ever kicked in, cause after it did you could say yourself "ok at this point I might be dead due my own negligence. Am I really fit for this machine after all?" So it feels like a solution to problem that should not exist in the first place... Always know your ppO2 (see, the mantra is already there without the course or the rebreather. I am in the phase where I am evaluating the possible choices for that

This is what I hoped it was. I like the idea of stable, well maintained ppO2 for more accurate deco calculations instead it going down to x, pumping up to y and then declining to somewhere between x and y before going back to y.

Also I would like the idea of it being electronically maintained in situations I have hands/mind full of other things. What I have read about KISS though, is that the users get to know their metabolic rate quite well and find themself using the addition kinda automatically in normal situations.

Anyways, would be nice to get some clarification for this.

Stefan took a lot of piccies of this at the show and talked to them in detail...so expect more info in the Report - although it was amusing that Gordan knew nothing about it - I was talking to him at the booth when someone rocked up with a leaflet!

The "French KISS" ws developed for a number of reasons and after many missed deadlines we opted simply to keep our mouths shut and not say anything until we had a tried and tested product. Our original premise was to stick to the KISS design and simply include the "parachute" spc purely as a safety. The unit at the show was the first generation handset, by the time we go to market we will have the second generation which will also increase depth limitations, these are still in testing so we don't have hard data yet. We do have a user definable SPC which is also ready to go, currently we would prefer to get our secong generation handsets completely tested before shipping so although we are now ready to take orders we will not be shipping for about 60 days.

Hmm, you might well think that from reading about the KISS operation but in practice it is remarkable stable (in my fairly limited experience) unless you're doing a lot of hard work, seasawing, drills or have a problem, in which case the fact thats its changed is a useful tell tale.

Decompression is a black art involving alot of voodoo, chance and virgin sacrifices... so unless your X & Y are a loooonnnngggg way apart I'd say its probably a minor concern.


Besides, I've learnt to stop assuming how these things work till I've tried them, some of them are far easier/harder than how they are commonly written about!

Still, the kit in question seems neat (despite the blue handset) and the buttons look to be an improvements over the VR3/Explorer, neither of which is close to perfect IMO.

Best to just wait and see which of the usual Crash-test-Dumbies gets one first?
