Nitrox
« on: 18 Sep 16, 15:44 »
I would like to find out if we are able to do and complete the course online since no practical involved.

You need to know how to use the O2 analyzer. Not sure where you got the info that no practical is involved.

no practical as in no open water dives are required. Just theory and O2 analyzer in the classroom.

When I did mine, my package comes with 1 actual dive.  The course is not just theory but needs to use the O2 analyzer as mentioned above.

I did my nitrox course with SSI 3 years ago in Phuket. Came with 2 dives - as was mentioned, have to learn to analyse the gas composition, set up dive computer to the correct O2 percentage, and also the dives were to near the O2 mix limit to ensure I was not susceptible to O2 toxicity.

Also got to immediately realise the euphoria of diving with Enriched Air  ;)

Just a quick thought I had about going NITROX certified. some questions if the veterans don't mind entertaining.
1.can i still dive air after being nitrox certified? will i get confused?
2.nitrox is still chargeable by many operators. does benefits override additional costs?
3.currently using a SUUNTO ZOOP NOVO. will i still be able to toggle between air and NITROX on the dive comp assuming some operators don't have NITROX and i have to dive air?
thanks!

1. Yes. Have to remember which gas mix to use. 21% O2 for air or your nitrox mix, commonly O2 32%.
2. Depends on what you want out of a dive. Personally my dive profile in places like indonesia when i shoot macro subjects in the 20+m range for a long time, nitrox is quite essential for me to have enough NDL time to shoot/video.
3. Yes you can toggle.

For Suunto Zoop, when you switch to Nitrox, you can't switch back to air within I think 24 or 48 hours, but you can still change the O2 mix to 21% when you have mixed of Nitrox and air during a dive trip.  But if you are going on difference trips, as long as it is more than 24 or 48 hours, you can switch back from Nitrox to air.

As for confusion, just make sure your dive come is set to the right air mix, should not have any confusion.

Most operator (including my LOB) charges use of Nitrox because that involved cost of buying pure Oxygen to do the gas mixing.

to avoid confusion, always set the divecomp to Nitrox mode 21%. Change it when you are doing higher %. Else it will default back to 21%. You will not be confused by this.
