    Teams are typically either 2 or 3. Any more than that and the teams get split into teams of two or three.

    4 = 2 teams of 2
    5 = 3 person team and 2 person team
    6 = 2 teams of 3 or 3 teams of 2.
    etc.

    I'm very new to deco diving, so I don't want to get out of my depth here (sorry, bad pun) but I compute my deco stops using air tables and actually use 80% for my shallow stops. So I would GUESS I have the ability to blow off at least some of my schedule.

    But I also realize many more people plan their dive based on their gas, and don't have that extra safety margin.

    I believe that Milt,at least, had the same instructor I did, and if so may have been following the same rules. But that is pure speculation, obviously he could have been planning his dives using his exact mixes.

    If they were a team of three then why did they split up?

    Would be very interested to see what there tanks had left for air and also there computer profiles for this dive.

    No. At least I'm not.

    Most deco programs have conservative factors built in and no one that I personally knows is running them using the minimal safety factors. Since there are so many individual variables that can contribute to DCS like rest, hydration, etc. I think anyone who is using the shortest possible safe limit is playing Russian Roulette with it.

    "Safe" varies from day to day and I think anyone planning their dives at the shortest limit is begging to get bit by it.

    Ideally, passing an injured diver off to surface support would be the way to go, but realistically how many people are using surface support for a 200' dive?

    I think most divers are planning dives to take into account ways of extending their deco times to cover lost deco gas, extra bottom time, etc. but very few have given much thought to how much deco they can comfortably cut out of the schedule.

    Because they weren't diving as a team.

    If the plan was to do 200' and then one person decided during the dive to stay at 140', then they effectively had a team of two and a solo diver.


    Just out of curiosity, why?

    A friend of mine calls this "Little House on the Prairie" scenarios. You can ALWAYS come up with a set of failures that makes something not work . . . but in real life, catastrophic failures are rare (if you are diligent) and the odds of having two of them on the same dive are astronomically low. On the other hand, if you do have someone with a gas issue in a team of three, you have TWO divers' worth of reserves to get him out on -- all of a sudden, that not-so-conservative third becomes two-thirds, and much more comforting.

    There's a little more info on the web now. The survivor said he discovered an air leak and surfaced blowing his safety stop. If that was the case the dive should have been called right there and his buddies should have helped him surface safely. Also read the other two made it through most of the dive and at some point during a stop something went wrong and that's when they surfaced. Still not all the specifics, but its getting a little less murky
