I'm with Joel.

Simplicity is key. I really like the Vision philosophy. Sure, it stays green in a wide range - but since your deco is off the actual PO2, you can handle a PO2 shift for a little while without bad consequences.

One problem in general is getting the chance to experience alarms. I had one on Sunday - one of my O2 cells was out of synch with the others. The alarm was brief and to the point - a red flash and a couple of beeps as it switched to ignoring that cell. It REALLY got my attention - I was hovering over the BOV switch as I checked the handset. That was after a very brief flash and beep - a continuous flash and beep would be impossible to ignore.

But I could see a continuous disco of flashes and colours finally getting your brain to tune them out.

So - I'm perfectly happy with my Vision, and like the "all steady green until there's a problem", in conjunction with their differentiating between one qiuck beep/flash to warn you of a minor event vs a more alarming process for something that needs interevention. This way when something flashes or beeps it gets your immediate undivided attention since it's so different from the flashless norm.
