but today, I doubt most of the folks here would book a trip w/o nitrox as an option.
they'd choose another liveaboard that had it.
Last couple liveaboards I've been on, out of roughly 20 spots, only 1-2 people don't dive nitrox.
I agree Mike, I pushed for getting nitrox on the boat from my first day working on the Pilot (I was the only nitrox instructor on the boat and I saw it as a way of increasing my own income as well as increasing the boat's income). I recognized in 1995 that nitrox was going to be the wave of the future, especially with PADI finally embracing the "devil gas." I debated it with JD for years and it wasn't until the competition started offering nitrox on a large scale that the company decided to follow the trend. Unfortunately for me, it didn't become available until I had left the boat. Unfortunately for Nekton guests, JD installed a system that was capable of delivering an unreliable and usually low mix.
I was merely suggesting that it was a stretch to blame a low mix (25%-28%) for contributing to cases of DCS. First, trained nitrox divers should base their dives on the mix actually provided, not on some magical 32% or 36% o2 level. Second, historical evidence demonstrated that when nitrox was not available (over a very long period with a large number of divers doing 4-5 dives a day) there were minimal cases of DCS.
