This is what the boat replied back to BubbleBoy's questions:
- What is the average diving depth, or typical daily profiles?
There are numerous walls starting shallow (30 ft or so) and going deeper than you
should dive :-) Each diver will be setting their own profile. Some guests
wouldn’t think about diving anywhere without nitrox, others won’t find it
worth the money.
- Will Nitrox likely permit additional dives each day?
No - you will just have to manage your time and depth more carefully
NOTE from SD: You are permitted to dive up to 5 dives a day. Nitrox can help you have more energy to do all of those dives. Nitrox can permit longer bottom times for those add'l dives especially if you dive max depths most of the day and you have a very conservative computer.
- Will there be an O2 tester on board?
- Yes
