Advance Nitrox or Deep Diver

[divemaster_jim]

The IANTD course progression isn't really that tricky.

The deep diver and the advanced nitrox together make up the entry level tech program. I think they could do away with the "deep diver" but it is air only and no staged decompression while the advanced nitroc isn't just air and does include minimal decompression. IMO, someone who wants to go as far, or further than advanced nitrox, doesn't nee the "deep diver course" for anything. So...you can combine then and it adds to the divers experience in that they have to do some more dives but there is a big overlap in skills and objectives.

They have recently added the recreational trimix courses but lets set that aside for a minute.

The "technical Diver" course is sort of like the TDI Advanced nitrox. 170 on air with 100 O2 allowed for decompression.

Normoxic trimix...200 ft with one decompression gas and it can be combined with the tech diver course ans presto-chango...no deep air.

Then of course, the advanced trimix which is self explanatory.

Now back to the recreational trimix classes...they can be combined with courses like advanced nitrox and, for those who care, you don't ever have to do a dive with an END below 80 ft.

They also have the "decompression specialist" class whic is classroom only and, if taken, lets you do the rec trimix/advanced nitrox combo down to 150 with 20 minutes of decompression and use 100% O2 for decompression.

ok, maybe more than what you really need but burried in there are a lot of options, no need to dive deep air and it isn't really all that hard to understand.

Is this something new? I didn't see it posted on their website.

Wait, Deco Specialist with NO diving?!?

Hi Andy, you can consider many agencies as IANTD, GUE, TDI, DSAT and NAUI etc
For IANTD standard prerequisites, diver must be an Advanced Open Water Diver, Nitrox certified and must be an IANTD Deep Diver or equivalent..
Equivalency is defined as an Advanced Open Water Diver with 50 logged dives, ten deeper than 27m/90’, and must pass the Deep Diver exam as a pre -assessment

You've got me, their whole web site has changed since I looked at it last. I didn't see the recreational trimix classes listed either...they used to be there though.

I didn't find their "Standards and Procedures" online anymore either and they used to be there too.

If I remember right, the Decompression Specialist course was anounced about the same time that the recreational trimix courses were anounced.

I can't say a whole bunch because I can no longer find the standards online but it was a classroom thing basically designed to go along with the advanced recreational trimix courses.

The diving was done in the other courses. The limits were just changed a little if you too k the decompression specialist course.
Taking the decompression specialist course let you use 100% O2 rather than being limited to 50% and go a few feet deeper and stay a few minutes longer while taking the rec trimix course.

That's from memory since I can't find the S&P.

Taken as a stand alone classroom only course, I don't know that it baught you any special access to anything...without the S&P I can't verify it but, maybe just learning as apposed to getting someones permission to do something. LOL lots of classes are that way...you sit in the classroom and learn stuff but as far as the rest of the world is concerned, you didn't earn any special privileges by doing so.

ok, maybe it's just to early in the morning.

the IANTD Standards and Procedures are here http://www.iantd.com/standards/IANTD_Standards_2003.pdf

Decompression Specialist
A. Purpose
1. This Program is designed to give the diver a better and deeper understanding of the models used for generating dive tables
and dive computer profiles. The program will also train students to use dive tables, dive computers and decompression
software programs.
2. Upon completion of this course dives will be made to 130 fsw (30 msw) using EAN 50 to 100 % oxygen for decompression
provided no stops are deeper than 20 fsw (6 msw) or longer than 10 minutes
B. Prerequisites
1. Must be a qualified Advanced EANx diver or equivalent.
C. Texts
1. IANTD Decompression Software Specialist Student Workbook.
2. IANTD Encyclopedia of Technical Diving.
3. CD-ROM Decompression Software Specialist.
D. Program Content
1. Complete all theory in the IANTD Decompression Software Specialist Student Workbook.
2. Complete the written exam with a minimum score of 80%.
3. Demonstrate the use of decompression software.
E. Equipment Requirements
1. There are no specific equipment requirements for this Program.
F. Program Limits
1. There are no diving activities required for this Program.
G. Water Skills Development
1. There are no specific water skills required for this Program.

I no longer see where any of the other courses limits are altered by taking this course...things change I guess.

Andy, you've said a couple of times that you don't have any interest or desire to do technical diving or even to dive doubles, but you have said that you want a class that will make you a "better" diver. What do you mean by that? Figuring out how you want to be "better" will help you choose a class.

If you want better buoyancy control, work on your trim, new propulsion techniques, refinement of emergency procedures, and to learn how to deploy an SMB, you could take GUE's Fundamentals class. You can do it in a single tank. You'll learn about gas management, some more about decompression, and a lot about diving as a team and about situational awareness. It does have equipment requirements, though.

Advanced Nitrox and Decompression is designed for people who want to do deeper diving requiring staged decompression. Although I'm sure you would learn quite a bit from such a class, I'm not sure how applicable a lot of it would be to the diving you are telling us you do, and want to continue to do.

Everybody got excited about this class versus that, but they seem to have missed your original parameters.

One thing a course like the Advanced nitrox courses do is help gain functional access to 130ish depths.

While it's often stated the the "recreational diving limit" is 130, you don't have much no-stop time so being able to plan on a few minutes of decompression and using a decompression gas lets you do a more worthwhile dive to 130 ft.

I know divers often bounce to 130 or so on reefs or whatever but wrecks are often more or less a square profile dive. Divers who are limited to a no-stop dive just aren't going to see much of that wreck.
