Got my rEvo

Alf

I know, I know... but starting without looking at the leds gives me the satisfaction of something starting well

Dave Sutton

Which is, BTW, exactly how we (and the Navy) use the Mark-15 Primary (color coded LED's with green ="on setpoint" ) mounted either on the wrist or the DSV, and how the Mark-16 Primary (HUD) is used. The digital (or analog) secndary is not normally referenced once setpoint is met.

The issue that some miss is that the HUD is a true PP02 indicator, not a "good/look at display" HUD, mas are some other less sophisticated systems. They *are* a primary display of PP02. What else would be seen on the handsets? A digital representation to compare to a graphic representation of *the same data*? It's the same data, driven by the same cell, processed by the same processor.

Dunno if I agree with Dave C that the HUD does not allow you to see the cells fluctuating. I run a fairly low flow, meaning that I am doing nmanual 02 injections every 5 minutes or so. I manually drive the PP02 to the "red/green" edge, watch it drop to green, and inject at the "green/orange" edge. Seems like that 5 minute cycle is letting me see the cell dynamics pretty clearly.

Best,


Dave

Find a Scubapro R190 reg. Nick the bits out of it. That's a rEvo ADV as far as I could tell.

almost!

(always try to use what is reliable, and proven over the years)

the only part you will miss is a connection between the R190 reg part and the 4/2.5 mm tubing...

9/16" UNF swivel to 1/8" NPT female with 4mm push-in connector.

Great idea. Oh and about 1" heat shrink tubing to stick on the lever.

Every time a new CCR emerges with a HUD, this argument raises its head.

I knew just where this would go, but I will say my thoughts for the last time on this thread.

My comments relate specifically to:

Where a guy who has just started to dive CCR is already saying that because of a HUD there is no need for regular attention to the rEvodreams.

Now, no criticism of Alf, who I do not know, nor Jacques, who I have known virtually for a number of years and for whom I have nothing but the greatest respect, but I have heard this argument already related to the Meg, the Ouroboros, the Evolution and Uri's HUD so many times I forget.

HUD's are great, during constant depth swimming or working they come into their own, but they are supported and or vindicated during depth changing swimming by the readouts on the handsets, in my opinion.

Jacques you have much more time than me on the rEvo, I have almost 30 hours, but I will still dive the way I dive & teach when I have 300 hours on it. This is not a criticism of the rEvo, which I think is a great piece of kit, otherwise I would not have bought one.

Rather, this is a plea, to not ignore the rEvodreams, they are there for a reason.

Now just to respond to Dave's comments.

Come on Mr Sutton, you know as well as I do that the MK15 and 16s were built for military applications where KISS is important as is lack of redundancy and the suchlike, what works for you & military divers will not necessarily work for ab-initio CCR divers or CCRs in the civilian domain.

It doesn't it shows when they are within or passing across or outside set parameters, I like to look at my cell readings physically tripping the numbers, not all the time, not every 5 minutes but every now and again. Just in the same way Dave that as you fly, even with a HUD display you will, I guess, still let your eyes roam, albeit very quickly, over your instrument panel artificial horizon, ASI and other gauges.

Now more light-heartedly........

Then dive somewhere else than Lac Leman! LOL!

Cheers,

Dave Cooper.

Just for my knowing, why the rEvo come with the SAME rEvodreams and the same HUDs?

It is not an other option to use an other kind of PpO2 reader, aka display tube for exemple on a pair of cells and the rEvodream on the other pair of cells?

In case of matter (flooding, electronic problem) on the rEvodream, will the HUD be still working?

Because I'm building my own CCR I'm looking in interest about these questions.


Stay safe, have great silents dives

Dave Sutton

Each rEvodream is completely isolated from the other. If you flood one, you loose it: Both the HUD and handset. But you have two complete systems, each connected to it's own cells. It's completely redundant. Loss of one has no affect on the other.

even better, if you cut of the HUD cable, the display keeps working :-)

paul

.... but why would you cut off the HUD ???

May I propose some rock in a cave, a piece of a wreck...May be...

I've seen fews rEvodreams and don't remember how solid they are, the cable is a classic Pirelli like or a special one?
