dive:
Is that the one you would want (the bigger one)
Honestly, I rather not. It's huge! That means moving it about is gonna be a real b!tch.
I don't know what the rating is, but if it's in the general neighborhood of either the PRISM or MK15.5 I would prefer either of those.
The Ouroboros is a very intresting design in general, and has many of the features that the Cis-Lunar MK-5P had. Elaborate electronics with deco, multiple separate batteries in multple locations, off-board gas connectors, advanced gas management (pressure sensors and digital contents gauges as well as gas isolation switches for solenoid and ADV), tertiary HUD display for system alarms, pO2 alarms and deco alarms (plus, in the Ouroboros solenoid alarm), buddy display (also more elaborate in the Ouroboros, repeating all four HUD LEDs
and showing the pO2 readout) and last but not least the space for a 4th sensor (currently VR3 for independent deco calculation).
The disadvantage of all of this is that whatever you do involves pushing buttons and scrolling through menus, selecting items on screen. I've never been the biggest fan of that sort of thing which is why the simplicity of the PRISM and MK15.5 appeals so much to me. When things go wrng on either rebreather actions to be taken by the diver are considerably easier to handle in my view.
While I like some of the features, especially the gas isolation and offboard connectors, they come at the price of added maintainance. Only worth it if you need it in book.
And they could be retrofitted to other rigs, too.
Below a look at the larger unit I photographed at DEMA in Miami Beach.
As you can see, it's a pretty large rebreather. Both images my © 2003.
