question regarding the dive or not to dive issue
when you do two back to back dives, or better yet three
1 - do you find a difference when diving air versues a best mix nitrox? do you "feel" any different.?
2 - Is your real dive exactly the same as the dive you planned for on paper?
do your answers offer any thoughts to the dive or no dive issue.
I offten combine the Nitrox class with aother such as drysuit etc

These questions are so good I started a new thread with 'em...
See "Does Nitrox 'Feel Good'"

Since most dive classes are more concerned with marketing, it was a backhanded joke.

OW teaches those skills, or is at least supposed to. So of course you have to practice those new skills.
Nitrox has nothing to do with those skills, if they're present, but your insistance that you're getting students that require, what was your word, "remediation" is just admitting that there's a problem in OW (or AOW or whatever is required these days before Nitrox).
Think outside the box (agency requirements). What would be a better approach?

I think I am usually among the first around here to acknowledge the problems that exist in training.
Ok, so MF wants to bring students into the water on Nitrox and fix the problems they might have, including but not limited to buoyancy problems.
My question is why, if you EXPECT that you might have buoyancy issues, do you want to bring a student into the water with a (let me overstate the case) dangerous gas where they could tox? Again, you can do EVERYTHING underwater with air that you can do with Nitrox and more, like blowing a arbitrary MOD depth without the risk factor. As instructors Id think youd want to reduce risk, dont you?
So if I were king, and you took a Nitrox class from me, Id do evaluation/training dives BEFORE the class. Dive 1 would work on basic buoyancy and see if its up to snuff doing some task loading (mask removal, donating air, etc.). Wed do this at a very shallow depth. Now your evaluation dive; your fictional back gas (really air) has a MOD of 30 feet. Id descend to 20 feet without any side or bottom reference, run some mask flood and clear drills, air share and swim around a bit. Anyone that comes back with a max depth of over 30 feet gets to start over next month.
Now Im left with students that know how to stay out of trouble. Off to the classroom, teach them the Nitrox formulas and give them their card.
Note that Ricks long litany of training skills like running a calculator on a boat (sure you dont want to break that out into another specialty?) and keeping track of tanks on a boat (talk about assuming your students are morons) are all ABOVE water skills. I have yet to hear of ONE SINGLE THING thats taught underwater which REQUIRES the student to actually dive a bottle Nitrox.
But there is a reason, and the reason is marketing. The agencies that force you into this ridiculous practice realize that they cant charge $200 for teaching someone four calculations.

You tell me, what new skills are you teaching and why in your advanced Nitrox class?Rick Murchison once bubbled...
So, you probably think the two pool sessions and four dives I require in my advanced Nitrox course are unnecessary too, right? After all, it's all just math and a little hovering...

on the orig question of which dive body to go with ...
when i first started out, i'd probably get both (the more cards the merrier
)
now i'd go with the agency that give most headroom/intro to more learning - because for me diving is an endevour that demands continous learning, and the fact that i enjoy different experiences.
i did PADI nitrox, followed by TDI Gas Blender followed by IANTD Adv Nitrox - the successive courses prompting me to read the manuals from successive agencies (e.g. read TDI and IANTD Basic Nitrox handbook) to ensure my learning is 'consistent' within one agency. maybe reading up the standards and procedures would have saved me more time
ut:
side note - i did gain from my confined and OW dives - the 'real prep time' is no longer just a classroom exercise but possibly a matter of life and death (gee, i do need to set the nitrox percentage on my computer, and the white table and the yellow table serve a diff purpose). plus, going to nitrox meant i was switching between HP100's to AL80 - diff bouyancy characteristics.
