Water ingress & recovery in KISS Classics

Are you sugestig Gorden wouldn't have evolved past his 1990s design?

The core unit is great thats why i have gone back to it, but intigrated deco display and HUD are I am sure things he would have added just as Kim and the team do now

No, that's the straw man you're creating to justify whatever unit your on at the moment and bears no relation to what I said. I've no interest in going down the rabbit hole of "here's why my unit is the right one" as usual.

I brought up about going from the triple redundant display to a non redundant shearwater.
I dive with a shearwater petrel reading the cells along with a HUD as I like it, I don't think of the
HUD as redundancy though so I know I've lost out on that.
I don't think it's the way Gordon would of wanted the unit dived and I'm fairly sure he would have
moved with the times but still found a way to have redundancy, just how I don't know but I'm sure
he would.
Bottom line is I find the KISS a fantastic unit, simple and reliable. It will do any diving I'm doing.
Lots of the mods I've tried have been removed and I'd say the only good one was cutting the case
like the explorer case to make access to the lungs easier.

But isn't the triple display also limited to the success or failure of the same three cells?

I don't think all HUDS are suitable to be considered redundant displays but the Shearwater with its independent controller and power supply and cell specific 3 LEDs showing actual PP02 meets all the needs I have to dive a CCR

OK but you can now buy a KISS with Shearwater display and Shearwater HUD as standard off the shelf kit?

Which in my view just shows the evolution of the unit. They looked at it and thaoght, that's an improvement and went with it

The core principle of fully manual and non electronic function, non invasive control unit remain, they just take advantage of a modern display.

Or trying to drum up sales by bolting on toys.

I can buy a pizza with cheeseburgers round the edge from Dominos. Just because people will buy it doesnt mean it's a good idea.

You could stick a Shearwater up the arse of a dead cat and a lot of people would hail it as the greatest technical development ever.

For me, it was a wrench going from three cells to Shearwater. The three independent displays are truly independent - there's no air / water connection between the cells.
However, once you have a shearwater, there are small holes link each of the three cell cavities in the kidney, so a flood in one could affect the others. (But I think it's unlikely)

I had a similar feeling going to the shearwater but I do like it
and it's not hard to pot the wires going between cells so doing
away with the openings in the cavities.
 
I am a huge fan of Shearwater stuff and think their products are the best currently available. I do feel it is important for this discussion to point out that the Shearwaters all use a common ground for the 3 cells. If that ground wire breaks, you will loose all 3 cell readings. Granted it is not common, but it has happened (usually due to the older cables of the fischer connector though).
 
I've just done 20 dives over a two week period and at the end there was about 10ml (2 teaspoons) in the exhale lung, 5ml in the inhale and about the same in the canister. I have a rolled towel in there so it doesn't slosh about.

If I could improve design for better water tolerance, I would T-piece the hoses onto the lungs. This would reduce the number of holes in the canister head and mean water can be trapped in the lungs. Drain valves in the lungs could then do the rest.

It might improve the WOB by removing the push-pull flow to the counter lungs.
