Another alternative is to take ANDI CSU which combines "deep diver" and "advanced nitrox". It covers theoretical (e.g., best mix, mod, end, etc.) and practical aspects of diving with two nitrox mixes up to 50% and has a depth limit of 130 fsw. We used a bp/w, long hose with single tank for backgas and an AL40 sling bottle. We did gas switching, air sharing when using sling or backgas, etc. The ANDI CSU course does not cover decompression diving.
 
PvilleStang:
I would recommend Adv. Nitrox and Deco, then deep, and maybe conbine deep and intro to trimix


Correct me if I'm wrong... I don't think IANTD has Deco program, It should be taught under adv nitrox and deep program.
While TDI has adv nitrox, extended range and deco procedure.

why do you think the TDI progression is better?
 
Eh, probably cause I took them. Had my experience with TDI, and don't have many complaints (other than the cheesy humor interwoven into the text). I'm sure if I'd gone the IANTD way, I'd be blessing their route.

Because I can understand the structure of their courses.
Nitrox,then Advanced Nitrox/Deco . That certifies you to 150 feet and 100% O2
Go dive and get experience.

IANTD just seems to have too many courses.

I think that's the problem in the end, is that IANTD doesn't have ENOUGH courses (deco). Again, I'm not familiar with with IANTD progression, but TDI's make plenty of sense.
 
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.

So Mike are you saying that I better take adv nitrox and forget about deep diver / deep air program since some of the program content is overlap?

I haven't heard about "decompression specialist" class before. Is it another option course that can be taken together with adv nitrox?

Pardon me for asking a lot, I don't know route :confused:
