I am currently researching on what training agency to go with for my basic, advance nitrox and extended range/deep diver etc. I have just one question

Why is it that the agencies have different depth limits on the extended range or courses after the Advance nitrox course?
Example IANTD Technical Diver is 180 fsw while DSAT Tec Deep Diver is only 165 fsw. I am assuming that since DSAT or PADI does not have a advance nitrox course, it is incorporated in the tec deep diver course and this course is the equivalent of the IANTD technical diver.

Axua,
Don't discount ANDI there are some experienced ANDI instructors in your neck of the woods. We also have another very experienced IT from Thailand that is frequently there (philippines) running classes..

ANDI CSU about equivalent to most agencies nitrox+advanced nitrox,
ANDI TSD adds 100% and limited deco to 50m
ANDI ERD ulimited gear, ulimed deco to 50m
ANDi TMD full trimix no depth or equipment limits

No.

IANTD Technical Diver is a little further on than the DSAT course. DSAT has only two stages whearas most agencies have three or more.

I am IANTD trained and would recommend the course. A friend has recently done the DSAT and it would appear to be a good course (even though many people critisise it because they can't equate PADI and tec diving).

You will find most people believe that the instructor, not the agency, is what is important at this level. The availability of someone you trust and idealy local to you should be what influences you - not depth limits.

Diving below 130 feet should ideally be undertaken with trimix, below 150 feet definately. IANTD Technical Diver is a trimix qualification DSAT Tec Deep is not.

Hope that helps

TDI for example has a depth limit of 150' for Decompression Procedures. (Advanced Nitrox is important to reduce deco time, etc.) TDI also offers an Extended Range course for diving air down to 180'.

I suspect these depth limit differences you describe are a holdover from the deep air days. You would probably (hopefully) discover your personal depth limit on air or leaned Nitrox regardless of your certification or agency. For me it's 160'. I will not go deeper until I am trained/certified in trimix. At 160' I "feel it" which of course means I am even more affected than I realize. This can also change from one day to the next at the same dive site/depth of course.

Look into GUE... There's a bit more critical when it comes to skills and gear configuration but IMHO they're the way to go.

You're right about deep air IMHO. I just completed my TDI Adv Nitrox/Deco course and have no plans of diving air any deeper than 150', and I'm carefully looking at approaching even that depth on air. I've been a bit below 150' before and the narcosis is... ummm... is prononced a good word? :) I notice it way before then, truth be told.

Please don't look at the "authorized depth" of a course in deciding which to take: IMHO the deeper they let you go on air, the worse. Look at the training offered instead.
 
NAUI offers a Technical Diver course. It includes, Technical Nitrox, Decompression Proceedures and Helitrox. Cert is good to 150'. This way you can avoid deep air training.
 
As a technical instructor for both PADI and IANTD I will not get into the differences and the pros and cons of either one. Both programs have solid course content and performance requirements. One agency is more experienced in the deep relm and digs more into the why's than just the do's and don'ts. I would say base your choice in the instructor avaliable to you. Pick their brain, find out why they teach tec, dive with them and watch their water habits. Talk to other tec divers about your instructor choice. In short learn everything you can about them before committing to a tec course. When deep the error chain is short. Learn why it is short and how to minumize the risks. Above all, never stop learning......Good Luck

I actually just finished an exploratory trip to the Philippines. I will be moving there in October and teaching both recreational and technical diving out of the Barrio Barretto area. In the mean time you could contact Alex Santos in Manila. He is IANTD Philippines and could stear you in the right direction.

Good Luck

I completely agree with south pacific diver. I am also a DSAT and IANTD instructor. You need to talk to your instructor, check out how experienced he is and if he may incooperates some skills from other training agencies in his training.

good luck and have fun
