Why do you have to attend Nitrox classes in order to use Nitrox?

:toilet

... they receive complaints about the facility I went to about twice a week.

I guess that's your shop she's talking about?

Apparently, you haven't met anyone who is math challenged.

On the contrary - I own 3 retail stores, and have kids working for me who need a calculator to count change, and can't figure out what 10% of $3.95 is in their head

Different people learn better different ways. Having a class covers those bases.

For some...

and for others, the course being taught by an instructor is redundant. Obviously, since PADI now has an online Nitrox course, they agree too.

By your logic, one could argue that we could shun all classroom training.

By my logic, I would. I never learned well in a classroom setting. Some people did. I dropped out of College early on. Didn't like school then, and I don't like formal education at all.

- Nitrox is as simple as diving is in general. You have to be able to read a dive table to dive on Air, and :11: there are dive tables for Nitrox too. So really, the math involved is no more than simple dive planning, and reading a table as well.

You can call my post arrogant, but if the classroom was so important, then why has PADI even dropped the classroom requirement??

hi guys,

hmm... just wondering, why do you have to attend the class to get a cert in order to dive nitrox?

the class... is it just a knowledge of calculations? awareness?

coz i think, in actual fact, you just go to the shop, and they will give you a nitrox mix tank, and you grab it and go down to the water. no?

or before "ordering" from the shop, do you need to do the calculation and tell the shop, what % do you need?

i have not tried, and no knowledge on this.

please enlighten, thanks.

Very simple answer...

So someone does not have to recover your body. :hanged:

Nitrox used wrong kills, quickly and without much warning, well at least warning to you, your buddy will see the convulsions and seizure before you drown.

Again this is BOLLOX. Air is a form of Nitrox, it just has the deepest MOD. You will also be narked out your skull before you reach this level :>. Again Any gas used wrong under water kills, Pure O2 is not Nitrox yet it shouldn't really be used below 6 metres. Finally little is known about how your body will deal with Oxygen, 'oxygen and the diver' showed that on different days, under different circumstances, the body can handle different ammounts of O2 exposure, before toxing.

As I posed elsewhere: Hell, "it" can happen at 1.2, but for years I (and many others, using what was thought to be the best information available) dove pure oxygen rebreathers to 30 feet without incident. We all had the now discontinued oxygen tolerance test.

Martial Arts Instructor , is that a new padi specialty?

Thank you for the clarification. Now I know how little regard to pay to any of your posts.

 

[Lehmann108]

Ahhhh....perhaps because its good to know one's *** from one's elbow before diving?

Hah , surely you are an instructor of (a) certain martial art(s) then, i never knew it was a general thing.

I'm figuring everything it would take to fill a single AL80 tank from empty to 3000psi one time. Obviously you would spread all those other expenses over a broad range of revenue generating products over a period of time. You wouldn't spend $500,000 to open a resturuant and serve the first dinner for $500,001.

Dude...you can't just figure your variable costs for filling a single bottle are the total of what it costs you to do airfills. This is Finance 101 we're talking here. Airfills are a distinct part of the operation. If they aren't covering variable costs, then you shut down the compressor and sell it off. If they are covering the variables, but not the fixed, it is still viable to run the compressor, but you are absolutely losing money on airfills.

Depreciation, monthly loan payments on the compressor, maintenance, parts, liability insurnace...that all factors in to what it costs you to fill a tank, whether you think it does or not. If you don't believe me, pick up a finance book and see for yourself.

Your restaurant would not do very well if you priced your meals based solely on the price of the ingredients and the salary of the chef. You do, in fact, have to factor in the cost of the plates and flatware, ovens, pots, pans, stoves, range hoods, and the cleaning crew that keeps the department of health off your case. If you don't believe that, then good luck with your restaurant. It will wind up like 80% of restaurants do in the first year of business.
