It goes to the root of human nature. Most HUD.s, rEVO included, are really secondary displays. Raw info has had decisions made on status etc. When it dispays different pulse rates, colors, etc, these indications are based on internal settings the machine makes, not you. i. e. rEvo assumes that if the PO2 is under .5 for 5 minutes, it shuts down.
Hi again Dale,
I think you're working under some misconceptions regarding the rEvodream. I'd be pleased to give you some hands-on time with one if you like. In fact, you can come for a trial of the entire rEvo if you want to come up for a day.
The rEvodream HUD is *not* a secondary display, it's an "alternate primary means of display" of the same information presented on the handset. Heck, you can turn the HUD off and tuck it away if you like. You *could* cut off the cable and toss it if you like. In any event, the rEvodream is just a darned good single or dual cell PP02 metering system. A single shared-system should *never* be used for a CCR without a second *completely independant* means of PP02 monitoring. Two schemes make sense: A dual rEvodream setup (as provided on the rEvo), or backup of a single rEvodream with a single cell PP02 monitor either of the simple display sort, or a deco computer. I'm building up a pair of KISS Modified Azimuths right now using the single rEvodream and a 3rd cell on a KISS Display right now in fact.
As for the auto shut-off, feel free to disable it. It's user selectable. All that means is that you need to shut it off manually after diving.
You're like me: Reading about this stuff, it all seems too complex and counterintuitive. Hands on it all makes sense after about 90 seconds. I ABSOLUTELY LOVE the fact that I can be struggling on the surface in a current, swimming hard to the tag-line, and clambering up the ladder and handing off stage bottles and STILL be able to know that my PP02 is viable hands-free. That's a HUGE advantage to the mCCR diver... and the HUD has become an indespensible part of my kit. I love it.
And, BTW: Going to another thread regarding ADV's... when the PP02 gets to GREEN+AMBER on the surface... I do a nose vent and an ADV triggering inhale. With *sensibly selected* diluents, this brings the PP02 *up* making 02 addition in this high-gain environment hands free even with a mCCR.
Best,
Dave
