ThatsSomeBadHatHarry:
can you clarify on what you just posted. there is still alot i need to learn about this subject. thanks.
In some people's opinion (mine, for example) the best use of nitrox is
not in increasing bottom time, but in decreasing nitrogen loading by increasing O2, and then diving it like it is regular 21% air. This decreases the chances of getting bent and lets you leave the water less N2 loaded, and (many say) feeling better.
You don't need a nitrox computer for that. In fact, it becomes a waste of money. Using nitrox and then using a nitrox computer to dive to your NDL limits is considered by some to be a poor way to dive (for safety reasons). But, lots of people do it, and the LDS will sell the nitrox class that way.
In your nitox class you'll get a table for tracking N2 loading, and then you just dive air tables or an air computer.
If you want to increase your bottom time, I would use the tables and dive the EAD (tables and formulas given in the class). In fact, if you start looking for a pattern in calculating EAD, you might discover that you don't need the nitrox tables/EAD tables at all.
My opinion is, I wouldn't waste a dime on a nitrox computer because it only encourages the diver to dive to nitrox NDL limits, which is not the best/safest use of EAN.
Other people's opinions very.
I will post this PM in your thread.
