TM,
GUE has a number of instructors dotted around the country. You can be pretty confident that the only people qualified to be GUE instructors are people who do nothing but dive -- so they can generally be invited to teach in any place where there are paying students. Here in the Bay Area, a local dive shop sponsors GUE classes by brining a GUE instructor down from Seattle. They don't advertise the classes at all, though, not even on their website, because GUE's max student:instructor ratio is 3:1.

Here's a couple articles about the dangers of deep air. Ask your instructors if breathing air deep will increase your CO2 levels. Then ask them how much more narcotic CO2 is than nitrogen. This is a biggie that most don't even know about. If something goes wrong on a deep air dive, and you build CO2 -- you're physiologically screwed.

Hi Waren,
Sounds like you've made up your mind! I think your GUE training will be great and good luck with it.
I guess i was fortunate to have an instructor from tdi who is up to date on his skills and techniques. We were taught deep stops and END's and yes i will run air on dives to 150 feet if there is no overhead enviorment. We do run trimix on dives deeper than 100 feet especially with penetration anything else wouldn't be wise....Guess I got some serious bag for the buck in my training and we are geared up like we came out of the HALCYON catalouge. Except for a few cold water adaptations.
In Canada Tdi doesn't even offer or endorse deep air anymore that is ( OLD SCHOOL) hopefully the USA will be following suit!
Enjoy those pressed steel tanks we've been using them before they had become the trendy tank to buy they absolutely rock!!!
I wish you many happy adventures and may you be one with the dive force!!
Peace NINJA:ninja:

Glad to hear that Ninja! I got my certs from TDI Canada, but that was several years ago. Hopefully, the rest of TDI will get their act together. I think the internet is making a huge impact on some of these agencies. People are learning at a very fast rate, including the dangers of deep air and out-dated tables. IANTD has eliminated deep air too in the US (or so I've heard). Unfortunately, they still advocate it's use in other countries.
GUE is leading this charge and others are reluctantly going along with it. Of course, you still have PADI and Naui developing their "Tech" programs that teaches deep air
.
Take care.

Hello,
I will give MY input on your questions. (If someone doesnt agree with me then you can private msg me and keep the flames off board)
Question 1)
NO you should *NOT* take the tdi classes because theres a TON of info that you need plus not to mention SKILL/expertise needed to correctly handle 100% o2. These guys push people out the door in a rather quick time and turn them loose with 100% o2. In my experience this is an accident waiting to happen.
Stay *AWAY* from the gue crap, its just that crap. They pull data from other sources and claim it as they invented it, not giving credit where credits due.
Question 2)
20-30 should be fine for most things.
Question 3)
Want the bottom line here? *PROFIT MARGINS* Shops seek the 150+% markup for various reasons and goes out of their way to get items at the lowest cost possible.
Want my recommendations or an oxygen regulator? Full face mask. Reason is simple. If you have any type of convulsions while at depth you wont drown and give your buddies(s) extra time to save you. If you want a standard regulator then go with the tx-50. No point of paying the extra $ for the same regulator with more gadgets.

Even though you chose GUE you still need to do get a background history on the instructor that you work with. I don't care what agency you go with, you still can have a bad instructor. There are several instructors that teach the DIR that are not with GUE. Ask the instructor that you get hooked up with to give you the info on the last ten students that he taught. If he says sorry, run!
Contact the students and ask questions:
Did they get their card in one weekend? If yes stay away.
Did he just go out of the book? If yes stay away.
Did the instructor talk DIR but dive DIW? If yes stay away.
Did the instructor like to talk about his big air dives? If yes stay away.
Did the instructor say that he was the end all of knowledge for that course? If Yes stay away.
Did the instructor ask his students what could have been covered more or done better? If No stay away.
Just remember that it comes down more to what the instructor does that what agency he is teaches out of.

I agree with OKDIR. Check the instructor out!! That is where the real information comes from. I'm currently in the middle of my TDI Adv. Nitrox/Deco procedures class and I can honestly say I have learned more about Nitrox, Oxygen, Physiology, dive planning,...etc than from any other class. All that information, I promise you it did not and will not come from the TDI manual. Those things are worthless!!
I was very fortunate to find an instructor that believes and teaches the DIR philosophy.
He takes his teaching very seriously and I promise you, you can't get the card from him in just one weekend. He follows the TDI standards, does the minimum dives, but if you still don't have the skills necessary.....you will keep diving until you do and actually EARN your piece of plastic (card).
I am a GUE fan, make no mistake, BUT I have heard of a guy that went to Florida to take a GUE class (Tech 1 or 2 I don't remember) and left after 2 or 3 days. He was getting nothing from the class, so he just left. This just made the point even more clear. ITS THE INSTRUCTOR, NOT THE AGENCY THAT MATTERS!
I feel better getting that off my chest. Oh, by the way Warren, if your getting into Cave diving I would definitely go the PST 104s instead of the 95s. Trust me I just got rid of some and bought the 104s.
Sorry about the length.

Glad that you're finally out of the closet, Ed, unlike the pussyfooting you were doing in http://www.scubaboard.com/t4173/s.html.
I guess I have to give you credit for that. Tell me, when are you heading down to Wakulla and show 'em how it's done?
I'm sure they'd be hanging on your every word about O2 cleaning too.
ALL the agencies have gotten information from elsewhere. GUE/DIR's only claim as to what's theirs is the cohesive, holistic system that they've come up with, rather than the hodgepodge TDI/IANTD approach of "whatever feels good to you."
