TDI certification? Extended Range interest

[Albion]

If the courses were combined, you were lucky. I don't think they are combined at the agency level, but it sounds like your instructor gave you a break. The ER required dives are supposed to performed before the normoxic dives with He. Some IANTD instructors are pushing students though recreational trimix in order to allow them to use He in the ER dives. I think the ER course is stupid and a waste of the students money. The concepts of N2 Narcosis and Ox-Tox are well covered in all IANTD's courses.

i will need to dig out the manual but i only had one which was headed ER and entry trimix. We did air dives first and then followed up with mix, which was a good comparison and allowed you to FEEL the difference. The site had good conditions, minimal current good viz, so i didnt feel at all narced on the air dives, so switching to mix (different dive) it wasnt immeadiate change but i did notice the air divers werent "with it"

I am also thinking to lean tec, but wondering if Padi is a good agency for tec...
Their TecDeep course seems to cover 3 TDI courses, but more expansive. How do you guys rate it in the Tec field?

Thanks in advance

Back in the 90s when ANDI, TDI, IANTD, were teaching people to safely with nitrox and dive deep with trimix PADI was saying that nitrox was dangerous and they would never teach people to use it. A few years later they act like they invented it.
PADI has good manuals and great rec programs. I teach many of them myself but when it comes to anything beyond rec limits I deal with an agency that has some credability.

How interesting, I became nitrox certified through PADI in 94', after they helped put a waiver in place to allow gases other than 21% for Instructors to be covered by OSHA in the states.

Prior to that, Instructors had no coverage in the states and was a real problem for people teaching those courses. Hmmmm, if that doesn't give credibility to an agency, I don't know what does.

I've done the TDI and IANTD thing too, look at the books and cue cards PADI has. They have a better and more complete program that has a beginning, middle and end that will make good tec divers. The rest lies with experience and frequency of dives.

I wasn't there so I can't say for sure but I am quoting Brett Gilliam here

But when PADI announced that it would introduce its own nitrox training program in 1996, the last bastion of resistance effectively fell. Now even the most strident opponents have eaten proverbial crow without so much as an orange sauce to make it go down easier

I found it here http://www.saa.org.uk/index/nitrox/Nitrox out of closet.htm
I prefer not to use heresay info but the evidence looks pretty compelling to me.

That indeed is a Bretism... (just one T) and one founded in fact. TDI was founded in 1994 (I was there) and none of the "mainstream' recreational agencies endorsed nitrox back then... nitrox use was seriously frowned upon and a course director for one large training agency took me aside in '95 to tell me I was "a ####ing idiot and irresponsible" to be teaching divers to use anything but air.

A couple of years later, that course director was teaching nitrox and it was trimix that was devil gas... and now look... Plus ca change...

And just to set the record straight, one is NOT required to take ER before starting a trimix program with TDI.


By the way, which 'breather are you using in your profile picture.

If you received a "PADI" nitrox certification in '94 it was a DISTINCTIVE specialty.. Right around this point PADI began allowing instructors who were recognized nitrox instructors from ANDI and IANTD to submit an outline for a distinctive specialty.. PADI came out with their nitrox class in 1996

PADI, DAN and SkinDiver magazine managed to get ANDI and IANTD temporarily banned from one DEMA (Don't remember exact year '91 or '92ish) for promiting "a gas thats going to kill divers"

It's half dreager, half kiss. Leon Scamahorn called it a mattel toy but I posted the upgrade pics here http://www.rebreatherworld.com/gallery/showimage.php?i=296&c=24

Ok guys, being the good card collecting diver I looked up my PADI certification date and it was 98'. They say the mind is the second thing to go, but I forgot what the first one was.

That means PADI was in the mix (pardon the pun) in the 90's.

There's a difference between being on the cutting edge and pushing the envelope. If the government has set regulations, fines can be assessed and the entire process thrown back years.

The Instructors teaching nitrox in the beginning were making a lot of money, because (as NOAA saw it) there were huge benefits. Hindsight being 20/20 all the agencys should have gotten together and put together a waiver a lot earlier. However, trying to get ego's like Gilliam, Rittowski and Betts to go with the flow is a bit of a challenge.

Sorry, I didn't mean to leave Cronin or Clark out of that ego thing.
