@stuartv I did say that the monitoring side is redundant, but the control side is not and that's an important distinction because failed 3-cell voting logic can wreak havoc on the system and there is no check against that, and as pointed out earlier, people have died because of it. You can't stop that from happening with any unit on the market with a solenoid except Liberty and Se7en.
Yes I have dove the Revo, yes in wetsuit, no it did not want to trim out. IIRC yours is Micro Titanium yes? I was diving a full size one at the time but I have heard form many full time Revo divers that with the full size units they don't behave well in wetsuits and are really foot heavy and with sidemounted bailouts are not divable in a wetsuit.
The fully redundant monitoring system is the "check" against what can kill you in a 3-cell unit.
I feel like there is some real waffling going on about this. Either, 3 cells can kill you because of voting logic and 2 bad cells, and that is a big deal - in which case 3 cells is clearly not as good as more cells with independent monitoring. Or, 3 cells can kill you because of voting logic and 2 bad cells, but it's not a big deal because, one, it is SO unlikely to happen, and, two, if you do have the 2 bad cells and voting logic that WOULD kill you, it's so easy to see it starting to happen, verify that you only have 1 good cell, and still get yourself out safely. In that scenario, it may be no big deal (to you), but I'd still rather have the 1 good cell plus 2 more good cells on my independent monitor to look at as I'm finishing my dive.
Personally, if I only had 3 cells total, and I knew that 2 of them had gone bad and I now have just 1 to monitor as I fly my unit manually through my exit and all my deco, my butt would be seriously puckered the whole way. I would have the constant nag, "how do I KNOW my 1 sensor is still good and accurate?" Can't be doing constant dil flushes the whole way out. You'd run out of dil, plus once you get away from the bottom, the dil flush isn't going to verify the sensor is working at the ppO2 level you're flying at. You could do flushes with offboard as you get to the right depths, to spike the ppO2 to a known safe level, to verify the sensor that way. But, I'd still be flying ;puckered and wondering if the 1 cell was crapping out at any moment. I mean, you know, 2 cells crapped out. Maybe something is going on in the unit and the 3rd one is about to get taken out by whatever took out the first 2. Maybe that would just be paranoia. Regardless, having an independent monitor system that lets me continually verify that 1 "good" cell still really is "good" would be very much of a relief - to me.
Yes, I have a Micro Titanium. I had a Mini Steel before that. My Micro has a somewhat heavy rEvo factory stainless stand on it. The Mini had a lighter Don Six stand on it. Both of them trimmed out just fine for me in any exposure protection.
The pictures above are older. Now that I think of it, I think those are all me in my old Mini.
Since my last training, in July, I swim my Micro with all my BO/deco attached sidemount style. Whether it's a single 40 or 3 x AL80, all slung SM-style, it still trims out the same for me.
I will note that my wing is a Dive Rite Nomad XT - not the default rEvo wing. I attribute some of the "easy" trim to that wing, as it is shaped to give more lift down low, compared to most wings. I had the Nomad on my Mini and moved it over to my Micro when I got that.
I dived yesterday with my friend who has my old Mini. It's got an Agir wing on it now. He seemed to have solid, flat trim - with no lead anywhere. But, he was in a drysuit and basically no undergarments.
You'll probably take that as justification for your early statements, because I'm not diving with the "intended" wing. Suit yourself (LOL!) on that. I think most CCRs have a wing you can buy with it, but are free to use any other standard wing that you want. Yay for rEvo for not locking you into using "their" wing and supporting use of any standard wing. I reckon if you use the wrong wing on any CCR, you can make it have bad trim.
