NEWreckDiver:I just completed the TecDeep course this past spring. The course materials are excellent. What will determine the quality of the class will be the instructor. Mine has been in the business for over twenty year and has dove everything from the Dora to the sites in Florida. My instructor have been a TDI instructor for year has been teaching this course for two years and tell me that it is a much better course.
If you are in the New Jersey area and want more information, send me a PM and I will get it to you.
Comparing the Padi Deep tech and TDI deco procedures isn't a valid comparison. The TDI classes are meant to be modular, while the PADI class is all in one..
Padi deep tec is about the same as TDI advanced nitrox plus deco procedures. The padi materials are excellent but very little wiggle room for the instructor. The TDI program varies depending on the instructor's experience and teaching abilities. Some instructors need the rigid structure of the PADI program some do not.
I personally chose not to pursue the Padi Deep Tech after looking through the course outline and reading their manuals (also their refusal to change some points that are definately wrong by definition, (the CNS halftimes comes to mind)).. I teach ANDI and TDI and am very familair with the IANTD programs. Unless a students specifically requests a TDI program I run the ANDI tech program which is probably the strongest academically out of all the programs. If I teach a TDI program I add in alot of the material that is required by the ANDI program.
Can a good diver come out of all these programs... Yes, but the deciding factor is the instructor.
