Huh? where'd you read that ?
I think if a crew member won't pull his weight, the captain (or the other crew) will deal with him. Trust me.
I'd like to point out that the above poster, Wookie, who runs the Spree, includes Nitrox for free on his liveaboard.
As a marketing and finance guy I'd like to point out that there is a tremendous difference between "free" and "already factored into the price."
:cool2:
Nothing is free.
You are correct, marketing guy. Free is when you pay nothing and I still fill your tanks. So, when you come to Key West and dive with another dive operator, and you come to me for your nitrox fills, even 50%, 70%, or 100%, you will still get those fills (assuming I am in port) at no charge. I believe that all mixtures of oxygen and nitrogen are there to make diving safer. So I do it for free. At no charge. When we're out on the boat, nitrox is included in the trip price. At that point it isn't free anymore, but included in the cost of the trip. If you don't believe, ask Carriesal, Texastorpedo, or oceanus.
2) 5 dives a day, several days in a row, exclusively on nitrox would have me worrying about pulmonary oxytox. I'd rather do 2 nitrox dives and 3 air dives per day(one of the air dives being the night dive). Probably doing air-air-nitrox-nitrox-air(might switch it around if the morning dives aren't deep)
