Online Nitrox Certification Course(s)

Good way to get people dead. What happens when the computer dies and a diver needs to do MOD's, EAD's, and best mixes the old way? Can they? What's your MOD for 26%?
And how does your CNS clock look after three dives with the mix?

Every shop I've gotten a fill from requires me to write the MOD directly on the tank myself when I pick up the tank.

When in doubt, stop diving. Simple solution, nobody dies, and worst thing that happens is you've wasted a couple hundred bucks. Not great but certainly not the end of the world and not worth making a big deal about.

That said, I took the TDI nitrox class simply because it taught tables vice (or plus) computers.

The formula for partial pressure of O2 in atm at any depth in feet is (depth/33+1) * FIO2 ( for 26% FIO2=.26) . If you set that to 1.4, the depth is the MOD, which you can solve for. Or you can download a nice iPhone app to work that out for you or use a spreadsheet or get a table. Any nitrox dive computer displays that as well. For 26% it's 145 feet.

As far as long term O2 toxicity you're unlikely to reach that in recreational diving.

Good point beaver...so I have a question. Do any of the well known organizations (PADI, SSI,SDI NAUI etc) allow a pure on-line only, card's coming in the mail nitrox course? If these guys don't, and another does, I'd be suspect. Even on-line colleges and universities require some direct contact with professors and classmates in order for you to complete the class.

As far as I know, all of the major SCUBA agencies require direct contact w/ a SCUBA instructor. I know for a fact, SCUBA Diving International (SDI) does.

I agree. If an agency just sends the Nitrox C-card w/o a follow-up w/ an instructor, then I would question that certification.

Not even going to bother. You get what you pay for. Just shows how trivialized training has become.

I would defer to the anesthesiologist on the gas breathing questions 😉
