Good day,
In the thread Accidents and Incidents > Cozumel Incident 9/4/11 it has been contended that some divers planned to dive to 300 ft on a single AL 80 or AL 100. Regardless of what happened in Cozumel and irrespective of whether or not these rumours are correct, I am curious how properly trained DIR divers would execute a dive to 300 ft. Let's say for a max bottom time of 10 minutes - just go to 300 ft, hang out there for 10 min, then head back. I am not interested in a recipe and I won't be trying this on my own. I'd be curious in a sketch based upon healthy divers with decent SAC rates. For example, would you likely have doubles plus stage bottles? Eight bottles per diver? Trimix? Deco obligations totaling eight hours? Support divers?
Again, please don't waste too much time. I just want to see how very different a DIR approach would be from a "bounce dive."
Thanks.
