    In Listen if you don’t take your snorkel on deep dives, we definitely can’t be friends!!! 🤣

    I wasn’t aware that was an option. I’ll look into the course info. Thanks!

    IANTD- Tech Diver vs. Adv. Rec. Trimix Plus???

    Thanks for the reply. I was fortunate to know quite a few people who trained with him and his reference list all checked out. He’s a very accomplished diver, is local to us, and is willing to tailor the training to our own schedules, goals and pursuits (my wife and I are both training with him)...

    He is and we like him quite well so I’m willing to overlook the agency. Seth

    Our local tech instructor teaches iantd and we just got through advanced nitrox and he brought up rec trimix. Started doing some research and here we are lol.

    Ahhhh! I assumed “gas blends” meant trimix. Easy choice then, thank you so much. I have zero desire to complete deep air dives. I don’t want to open a can of worms, but I can see how this agency’s coursework diverges from others. I’m not sure why anyone teaches deep air anymore, other than...

    Hey Everyone, First off, I've been searching through the forum and I haven't found the answer to this question. If I missed some threads, I'm sorry in advance, and thank you for posting them. That being said, I have a question that is specific to IANTD's coursework. I mean no offense, but I...

    There is a difference between diving something that is preferable versus being able to dive any setup. I can dive a jacket, I just don't want to. I'm not, and I don't believe anyone is, saying that John isn't capable of diving with ANY setup lol. Seth

    Sorry, I should have specified. I chose 32% as a "standard" recreational blend that divers would likely use. I just picked that number out of thin air to make my calculations. Seth

    THANK YOU! Had I just went to my notes I would have found the equation lol. Cheers!!!

    If that is the case, that explains everything. At 130' your po2 on 32% is 1.6. At 1.6 for 20 min you are at 44.44 CNS% and 38.48 OTUs. My tables won't even tell me what p02 you'd have at 160' using 32EANX (I'm guessing 2.0?) If you couple that with your residual then you would most likely...

    I re-read your post and have a question- Are you saying you did three dives in a single day, the first being on nitrox and the second and third being on air? Or are you saying you did a single nitrox dive one day followed by two deep air dives on the next day? Depending on mix, depth, time...
