Hi,
This January I took an Advanced Nitrox cross-over course with IANTD (in which I haven't finished yet) and my IT told me that the 6 meters standard was reduced to 4 meters. Wael
So as a diver that is taking responsibility for yourself, which do you do? O2 deco at 6m or at 4m like IANTD told you?
Do you know why IANTD dropped to 4m? Do you understand the offgassing difference between O2 deco at 6m vs 4m? Was the change made for reasons that are relevant to you? Or have you just put responsibility for this decision in the hands of the hierarchy of a training agency who you have likely never met?
