Techdiving Classes ?? TDI ??

[kanonfodr]

Actually recent thinking is starting to consider the reduction of CNS narcosis via helium may exacerbate the CNS toxicity of O2. So on trimix with significant workload at ppO2 of 1.4 is "worse" than the same ppo2 on just nitrox/air. Google Liz Halbach's death for an example, or there's an IUCRR report, date = July 14,2007

Wow...definitely puts the thinking cap on. Appreciate the reading, as somber as it was.

Peace,
Greg

Thanks for all the info guys and to those who doubt upon me in some ealrlier posts why take the time to post if you dont like my ideas go jump off a cliff yourself

speedyal, that's a very ungracious response, and not one that's likely to gain you good information when you have future questions.

Whenever someone asks about advanced diving, without phrasing the question so that it is obvious that they have given thought to the matter and are properly prepared, they are going to get a bunch of answers doubting whether they are ready, sufficiently experienced, or have the proper attitude for the training they're asking about, or the dives they want to do. Although it may be roughly phrased, it's actually people caring . . . people not wanting to see someone go too far, too fast and end up a statistic.

In addition, on any internet forum, the level of tact varies. You need a tough skin to ask questions on line.

My gosh, and please don't take this wrong, but how can you spend a year taking a first level technical class? Get it done my friend and move forward!

Ok im thinking about taking up tech diving does anyone know the course schedule for becoming a tech diver ?

I went to my dive shop today and the way he talked theres alot of classes invloved just to dive 150 feet

Anything you guys know would be of great help Cya on the bottom

Well, your profile says 100-199 dives and contains no info on what training you've already had. Impossible to answer your question without more information. Do you have your OW card and 100 dives to 30ft in crystal-clear 80deg Caribbean waters, or do you have OW, AOW, Rescue, Deep, Nitrox certs and have 199 dives off NJ to 130' in 10ft of vis with bottom temps in the high 30's?

Forgetting how long each course takes, here's what I might expect to see someone have before even starting tech training...

OW
AOW (or equivalent experience)
Nitrox cert
Rescue cert (+/- depending on which agency you did AOW with)
Deep cert (or equivalent experience)
Fairly good buoyancy control, trim and propulsion techniques
Drysuit cert (or equivalent experience) if diving/training outside the tropics

So, how much of that training do you need to get out of the way before STARTING Tech Training?

Then, once you start tech training it depends on which agency and how "tech" you want to get. I did my tech training with a DSAT instructor. Under the current curriculum you'd need to go through Tec 40, Tec 45, and Tec 50 to be certified to 150' (165' actually.) The prerequisites through Tec 50 are...

• PADI Advanced Open Water Diver (or qualifying certification from another organization)
• PADI Rescue Diver (or qualifying certification from another organization)
• PADI Enriched Air Diver (or qualifying certification from another organization)
• PADI Deep Diver (or qualifying certification from another organization)
• PADI TEC 45 certification (or equivalent)
• Have a minimum of 100 logged dives of which 20 must be enriched air dives, 25 dives must be deeper than 18 metres/60 feet and at least 15 dives must be deeper than 30 metres/100 feet
• Minimum age: 18 years old

(Note: Advanced EANx and deco procedures are part of the 40/45 courses)

I'm not sure total number of dives required under the new 40/45/50 curriculum, but it was a total of 12 under the old Tec-1 and Tec-Deep format. This was on top of pool sessions, classroom sessions, non-diving practical sessions, and many hours of home study. It took me about 6 months from start to finish due to scheduling, the need to repeat several dives in order to move forward, and the fact that I did Tec 1 in the Fall and Tec-Deep in the Spring.

One of the key mindsets to tech diving is "go slow" and this extends to training and gaining experience as well. This is why when someone asks "how quickly can I..." or otherwise sounds impatient... red flags go up for tech divers. (NB: telling them to jump off a cliff also tends to cause red flags to go up.)

"Slow is smooth, and smooth is fast."

Thank you so much this was extremely informative and the cliff comment was directed to the narcissistic gems running around spreading there insular views on the rest of the world trying to bring those down who aspire to further thereselves

Happy diving and thanks to all who have provided help

TDI.

Nitrox as pre requisite for-
Advanced Nitrox.
Decompression Procedures.
Extended Range, either air, or trimix.
Hypoxic Trimix.

Correct on the TDI courses! I certified under Joe Odom with TDI and I can't say enough good about him as an Instructor, but of course he wrote the books on some of the courses.

If you go through a course with TDI, you can be assured you will know and understand the risks and know you need to dive the rules and follow the dive plan - "If something seems wrong on a dive, it IS wrong! ... abort the dive!"

Keep in mind, it is ultimately the instructor, and not the agency, that instills the education and inspiration.

Let me open up a can of worms here:

Why is rescue diver a prerequisite to tech diving? I perfectly understand requiring rescue for DM, instructor, etc., but for deco? Because it's more dangerous? so is cavern, cave, deep, drysuit, spearfishing, altitude, nitrox, etc. Are agencies going to start requiring rescue for every class we take? Why not teach rescue first and then OW?

I'm not saying the rescue class is a bad idea, or that it's a waste of time, I'm saying that REQUIRING that class before teaching deco procedures is unreasonable...

At least that's my current opinion.... I'm open to having my mind changed by a wiser diver

Just do it with TDI. No Rescue Diver cert needed, (Though its an excellent idea)

Maybe PADI are just trying to sell classes??
