I feel compelled to add a few comments here. I was the dive buddy of the original poster on the dive, and this event has really bothered me since it happened. Heres some additional facts:
Me and my buddy and the other people on our boat arrived at the resort on Saturday, and did shore dives to get properly weighted and ready for boat diving Sunday. On Sunday our first dive was not a deep dive, but a check-out dive, at Chankanaab, where our max depth was only 47 feet (the dive op's choice, not ours). Then Monday, our 1st dive was more challenging, at 81 feet.
On Tuesday, the 2 newbies arrived and hopped on our boat, and announced to all this was their 1st boat dive and 1st ocean dive. The newbies never got a check-out dive as the rest of us did the dive op just stuck them on our boat, which of course was the economical choice for the dive op. No idea if they recommended the newbies hire a private DM for the day or not.
I did not see the DM give them any special instructions at all on the way to the site just the same very basic briefing we all got, as a group. I was surprised how casual the DM was. My take is that the newbies didnt have any idea what they were in for, and didnt know what to ask - they figured it must be ok if the DM was taking them with us.
Once we were down, my buddy and I were watching the newbies way, way more than the DM, but unfortunately we never checked their air. The DM checked the newbies air only once, about 10 minutes into the dive. I really wish I had taken the initiative to go over and check it myself a few times, but I didnt. I noticed and was surprised how little attention the DM paid to the newbies the entire dive he hardly ever even looked back at them (he was in the lead position, followed by me, buddy, and the newbies).
I understand fully the posters who assess the majority of the blame on the new divers rather than on the DM and I would agree with you if the newbies had even 10 or 15 ocean dives under their belt but they didnt. They were so new, they didnt know what they didnt know. I think they were so overwhelmed with the whole experience of being in clear water, with tons of fish, coral and life around them, and seeing a huge drop off into the blue to their left, that they just didnt think to check their pressure gauge. So I assess 80% of the blame/responsibility for newbie #1s OOA and newbie #2s attempted uncontrolled 70 foot ascent, on the DM for not giving them a thorough briefing and for not watching them, especially 20 minutes into the dive when they might have started to run low (he was OOA at around 25 minutes into the dive).
After that dive, I think the OOA diver learned his lesson I saw him check his pressure frequently on subsequent dives. The DM paid more attention to him also.
I learned a lesson also I am going to be more proactive in following my instincts concerning new divers, a lot more vigilant in watching for signs of trouble in other divers, and I may even proactively check new divers pressure during dives, if the DM is not. I hope I never get in another situation like this again, but I do feel better prepared if it ever happens again.
