"I should have refused it. But It was the last tank with 30%O2, and Nitrox was one of my credits for ADV. Open Water."

Ask yourself, if you ran out of gas and didn't make it back, would it have been worth the risk you took?

Whenever I dive I always remember what one of my technical dive intructors said (Brian Carney, President of TDI/SDI), "The number-one mission of the dive is to come back alive."

It is very unfortunate that true dive planning in not taught until you become a technical diver. By that I mean knowing *ahead* of time how long your gas will last, when it is time to "turn the dive", etc. Determining a precise schedule and following it is exactly what Hal Watts meant when he coined the phrase "Plan your dive and dive your plan." This, above all, is my biggest complaint about the weakness in the courses for certifying recreational divers with regard to safety.
