Do I need Nitrox?

[PerroneFord]

His question was Do I need Nitrox? And the simple answer to that is no.

AGREED!

Playing with V Planner (+2 conservatism) the NDL at 30 feet seems to be around 3500 minutes. i.e. over 2 DAYS !!

Not quite what V Planner is designed for,but pretty obvious that dives of a couple of hours at less than 30 feet are just fine.

You would have to have a computer compatible with nitrox and your regs have to be compatible with the mixes you'd be using too.

Is that for air or for a nitrox mix?

That was for air.

Using 32% the NDL seems to be infinite but it gets upset with the oxygen.

DIVE PLAN
Surface interval = 1 day 0 hr 0 min.

Any regulator is compatible with recrational Nitrox (<=40%)

You would have to have a computer compatible with nitrox and your regs have to be compatible with the mixes you'd be using too.
