why is he still on a tank after he is out of the water? is that a deco tank? is that necessary only cause he went to 200m?

[fire diver]

Yes, he is most likely breathing off a tank of pure oxygen. The Green guage covers are a clue that it is for high O2 use only. It is common for divers to hang in the water, at the surface and breath O2 for a while to help off-gas.

I agree. I think it's pure O2. It looks like there is a 6 for the MOD. I'm guessing that's 6 meters or about 20 ft. That's the deepest you can go on almost pure O2.

[cummings66]

I'll chime in, yes it's an O2 tank and the mod is in meters. Further evidence is his lying down and the lack of movement afterwards, all techniques to off gas.

thanks for clearing that up guys.
i take it that trough the dive, on the way up he does a few different stops on mixed gases?
Also, how long does a dive like that last?

i also saw a pretty disturbing video at the same dive spot last night, some diver in 2000 died, and it was all recorded on his head camera. kept me up for a bit... every time it would get too quiet in my room i would wake up again. it was sad, and made me think a lot. I've seen the "worst accidents ever caught on tape" or "faces of death" videos, and the video i saw last night was by far worst than anything i had ever seen.

[fire diver]

Yeah I've seen that video. Pretty disturbing, but I think it should be required viewing for all new dive students.

i agree, it made me re read my ow book (in the prosces now) and look into taking other courses in the near future.

[BSea]

I saw that also. You kept wanting to tell him to go up. That's why getting narced is so dangerous. 1 more reason to use nitrox in my opinion.

without seeing the vid, I am gonna say he is breathing 02.

edit: this reply to OP and judging by other replies I was correct.

(still haven't looked at the vid)

If it's the video I saw, you're wrong. The guy was apparently OK at about 100' then proceeded to keep going down. He was talking, then later nothing but gibberish. They found him where the video stopped at about 300'.
