TDI vs IANTD

[Meng_Tze]

or you can skip Extended Range and go straight to Trimix (after Adv Nitrox/Decp Procs)

Where is this spelled out? I am only aware of a 1.5 ppO2 limit with no fO2 limit for deco mixes. My IANTD Standards document is from Aug 2007. Perhaps there is something newer?

BTW, OP, I got Adv EANx, Deco Proc, and Adv Recreational Trimix all at the same time and the content all flowed together into one nice basket of related concepts. I endorse that approach if you can find the time. There was TDI, IANTD, and some example DSAT content used for the class and I ended up with a mix of cards from TDI and IANTD. My instructor was willing to follow the standards of whatever agency I cared to be certed by for the same price. Ask the instructor - it's a good question and if you don't get a satisfactory explanation, look elsewhere for instruction. Communication between you and your mentor-for-hire should be free and easy. Let this be a test of that!

It's spelled out in IANTD's standards and procedures, Page 43 in the revised edition that I have. "This program qualifies divers to do dives to 140 fsw (42 msw) and do decompression stop required dives up to 15 minutes"

Is that 2008 version on Page 43? I was just valildating the 1.5 ppO2 on the phone with my instructor the other night when this O2 % issue came up. According to him that is the latest standard. I hadn't heard about a time limit on the deco. I will need to touch base with him on that one now. He is an IANTD instructor, and apparently they just updated some of their standards for 2008.

Thanks for the post.

When I spoke to John Jones, who is an IANTD Instructor Trainer Trainer, at DEMA in October 2007 he stated to me that the Advanced Nitrox Program qualifies the diver to a depth of 140 ft. and only up to 15 minutes of decompression. He also informed me that the program certifies the graduate to use only up to 50 % nitrox not 100%. The standards may have changed in 2008, I really don't know.
