Vision vs. Optima

The way it should be..
Ther is no substition for a true fully manual method of control in those rare brown pants moments..

I agree.

That secondary set-up is ideal, and I would love to have the same capability on all of my rigs since you could even deco out on SCR as long as the sensors are still working.

Bruce, are you listening ? All you need is the option for a right-hand cable to the Shearwater computer.

Perhaps you could ask Stuart to write an applet that inserts a default- "Buy a Meg instead" post in every thread asking which rebreather to buy?

Oh and BTW- Buy a KISS instead
MCCR RULES!

with the hammerhead set up would you feel comfortable continuing to dive on a trip, driving manually, using the secondary after a primary failure, or is this configuration only intended to be used for bail out? the vision will allow you to finish a dive using either controller through the HUD and or handset... as soon as you go through the pre-dive check again, you will likely get locked out if the problem can't be addressed.

For expedition diving, the issue is what you do for subequent dives on a remote trip. It appears that there is no rebreather that comes stock with enough redundancy to safely continue diving after a primary failure...after market retrofit is required for that level of redundancy no matter what brand you go with.

this has lead me in the direction of two fully independent po2 meters, one with deco, one pure po2, and a third po2 meter, mothballed but ready to go... admitedly that exceeds most people's requirements to the point of overkill. for me it assures that I always have at least two 3 cell po2 meters to cross check...what I need to feel comfortable continuing to dive on a trip after a malfunction.

I am looking at doing some deep diving(100+) FT I live in Jacksonville FL so most of the diving is 70 FT plus anyways, I am interested in doing some wreck penetration and maybe even limited cave or cavern diving. I see the benefit in the reduced helium usage for the deep stuff. I also want something that I can do a tech dive on one day and then go out and dive with my recreational friends the next. I may someday end up with both or more for that matter but right now I am a little limited in the cash department since I am studying to become a Marine Biologist.

Personally I would.

I would dive anything as long as I have a mean to monitor my PO2 reliably.

Electronic-controlled or orifice-flow are nice to have items just to reduce the frequency of manual additions.

I wouldn't have a problem flying the unit manually to continue most trips (shallow 60m/200fsw or so) I'd just leave the battery out of the primary and tuck it away somehwere.... On bigger dives, It would be on a case by case basis.... I would use an integrated DC as the backup to the secondary..

Hi Gil, from looking at the pictures and reading Kevin's description of the new HH functions, it seems like the handsets don't "talk" to one another or "hand off", so the 2dry with the deco option would be suitable as a primary as long as a bad solenoid can be disabled, which if I remember correctly the HH allows for. For me, if I were going to go the integrated deco route, I would want absolutely no "talking" or "handing off" btw handsets/controllers-keep it as simple as possible, no added complexity, no fancy computer functions making decisions for me beyond SP control and deco.



Well, there certainly are ECCRs out there which have enough built in redundancy to complete a trip as an MCCR-Mks, Prism, probably Boris, maybe new HH. The problem comes from insisting on integrated deco, which adds complexity for what IMHO, provides little benefit over a stand alone deco comp.

While I have my own approaches handling planning for expedition type trips, you should consider the fact that the HH on either a Classic YBOD or Optima comes ready to support a 4th cell out of the box.

Dive Safe...
