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

[superkingkong]

PEACE!

i'm not here to create war. it's just that i'm a bit comfuse and maybe i thought here is is a place to ask question. but turns out, ... i don't know.

anyway, yeah, although i'm Nitrox certified by PSAI, but i can tell you that i know a lil bit here and there. it happened that i saw this dive shop, is organising a nitrox course, quite cheap though, yes, no manuals, no dives or whatsoever, it's plan theory. during the presentation, using powerpoint slides, i was taught with all that calculation and stuff, and of course, they taught me how to analyse a tank. that's all. according to them, manual is not here yet, so, it's plainly remembering. so, it happened that this course was conducted on the night before i flew to US. and i still need to rush back to pack my stuff for tomorrow's flight.

so, all in all, i couldn't get much out of it. i don't have anything to read on, to refresh my memory. so, i'm thinking either to get a Padi nitrox here, or maybe, until i go back, ask them for a refreshment course.

now, about my question, i've seen some shops, read from the website, stating, we provide EAN32,

well, since ean32 mod is 111', do we just grab the EAN32 tank and dive within 111'? or do i still need to analyse the tank myself? will the shop provide an analyser?

Most shops will supply and analyzer, check it against air then check you bottle. I have my own and I check everything I dive now, can't trust a damn thing. I've heard of folks getting rich tanks at places that don't even fill NITROX (that must take some doing, a rich fill elsewhere with no sticker or anything).

 

[superkingkong]

hmm, can i tell the op that maybe i need my own EANx value and ask them to blend for me? .. so that i can go to certain depth fro certain duration?

i guess blending will take a lot of times, right?

That's funny.

Don't read between the lines... read what I said. WHY DOES AN INSTRUCTOR HAVE TO TEACH IT TO YOU?

Can't this stuff be learned by READING THE BOOK?

It's not that hard... it's simple math.

Apparently, you haven't met anyone who is math challenged. I am not. However, many people I know are. Quite a few of them have taken EANx courses, and have gone on to understand the concepts just fine. However, they would not have gained that understanding just by reading the book. Different people learn better different ways. Having a class covers those bases.

By your logic, one could argue that we could shun all classroom training, and go back to the days when people read magazine articles, bought a tank and a reg, and went out and taught themselves to dive. I don't know about you, but I think we are better off now than we were back then...

Folks who are math challanged will not be able to do the exercises or complete the test. Have OPTIONAL classes for them. Folks who are not math challanged should not have to waste their time and money listening to an instructor talk about what they have already learned by reading the book. Especially those instructors who have had to overcome their math challange to get there.

Where's the profit in pandering to the non-math challanged?

Are you factoring in the cost (gas or electric) of running the compressor? Depreciation on the compressor? The loan payments that you're making for buying the compressor? Periodic maintenance of the compressor? Parts & labor?

How about how many tanks they are filling at $15/pop per month? This is, after all, a question of breakevens. Economies of scale dictate that based on volume, your breakeven price may be considerably different than someone else's in another geographic region...or even right down the street.

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.

This is the diving biz, the would if they could ... but they can't.

Martial Arts Instructor , is that a new padi specialty?

Hey ... I thought it was marital arts! What a difference the location of "I" makes.
