minnesota01r6:"I think OOG is the result of a poorly thought out dive. We should be taught how NOT to run out of gas in the first place."
That is not absurd at all and you are not getting that point. You can have a mechanical failure and lose your air and then go to your buddy's air, but if you run out of air because you are not paying attention or dicking around AND you have no buddy or redudancy, then that's inexcusable. Running out of air is very bad and there is little education in the area of how not to run out of air. A lot of technical diving training is teaching your how not to run out of air because then you are dead. This is not just DIR. I can quote you TDI if that's what you want.
You need more experience to really understand this.
