Errr.. no way you can stay at 30m for even 0.5hr - it's not a matter of air consumption or enough air or not, but being seriously in decomp time as Waisj pointed out. I think at 30m, you get only about 9-12 min bottom time on yr computer, so if you stay 0.5hr, i suspect that one may not have enough air for decomp.beivied said:ya thats what i think too. maybe he did multilevel but only remembered the 30m part, haha.. thats what i think la. still think not very possible to do 30m for one hour.. 70min at 12-15 min i was only left with 40bar then. not a very low air consumer then, but still.. my deep dive this time 31m for 30min-35min or so actual bottom time excluding safety stop i left 90bar.... one hour? bu hui ba.
and he didnt mention safety stop at all...
Wah, beivied - your photos so "swee" ah?! :thumbsup: good job!
