    So for example, if you're at 30 meters average or max depth for 10 minutes with nominal exertion:
    30m is 4 ATA (30 meters divided-by-10 plus 1 equals 4 ATA);
    4 ATA mulitplied-by 1 bar/min, and then multiplied by 10 minutes equals 40 bar consumed in that time frame of 10 minutes at 30 meters.

    You really don't need your Air Integrated Computer to tell you this anymore --just simply a standard "brass & glass" SPG in bar units and rote common sense . . .

    Because you really don't need that level of precision (i.e. an AI computer updating your consumption every 4 seconds); there is no added-value in purchasing a $1k Air-Integrated Computer when you can easily accomplish the same task with you own brain power & rote experience, especially when working smartly in the metric system with a value of 1 bar per minute. . .

    Again, how hard is it to use a unity reference value of "1", along with scalar multiples or percentages of that value???

    GramsciBeat, I bet your tropical warm water SCR will range from 10 - 13 litres/min to start --and go ahead and ebay that AI transmitter/transducer (keep the computer)

    @Kevrumbo: I think you've completely missed the point of beaverdivers' posts here on ScubaBoard. He sells Scubapro dive gear for a living. I'm kind of shocked that he only wears two dive computers on every dive. I would think he'd advocate for wearing at least three computers -- in case both computers crap out, you know.
    From his point of view, it makes perfect sense to sell unnecessary expensive equipment (or the gear with the highest profit margin) to a diver.

    What would you do? ScubaBoard has a "What if...?" series geared for beginner divers.
