I am a fairly new diver and I just want to give my personal experience with conventional recreational diving and DIR diving. My wife and I got into diving about a year ago and started on a path of taking a bunch of classes through PADI, which at the time seemed like the agency to get training from. We took OW, AOW, Rescue and then some specialties. At the end of that we still didn't really feel all that comfortable and confident in the water. I thought my wife may give up diving all together-there was a weird anxiety before every dive and it was starting to make diving not so much fun, but more like a challenge. So to maybe head off losing my dive buddy, I started to look into the DIR philosophy. I thought she might respond really well to this "style" of diving-she likes structure and order, the idea that everything has a place. I talked with a UTD instructor in our area and he talked with both of us at length. We looked at the course materials. We signed up for the class at took it in late Feb. of this year. The training that we received so far surpassed everything that we were taught before. I really felt cheated by our previous instruction-why weren't we taught gas planning, propulsion techniques (more than one), doing skills while not sitting on the ocean floor, how to plan a dive, who is responsible for what, proper gas choices-the list is kind of endless. I also understood right away that this class was going to take a LOT more effort from us as students.
I am glad we did it for a lot of reasons. Yes, the training was rigorous and at times hard to watch (the video de-brief sessions), but I figure any hobby you have to go on life support to engage in probably deserves some pretty intense training. I like that they pushed us, made us learn some simple math, made us learn basic underwater communication, put our computers in gauge mode, etc and I also like that now when I dive with someone other than my wife I know they are on the same exact page as I am. My wife does not have the pre-dive anxiety that she used to, and the whole thing is a lot more fun now-for both of us. We look forward to diving instead of kind of fearing it.
Our instructors were the first DIR divers I had actually seen in the water. That made a huge impression on me. They were so calm, still and in control in the water. Elegant would be a good word to describe it. I had not ever seen anything like it before.
I don't understand some of the internet attitude that I see expressed by DIR practitioners-every single one that I have met in real life has been really kind, helpful, supportive and patient.
I don't really want to get into the whole gear thing. In the Essentials class, the only requirements were non-split fins (so you can learn all of the propulsion techniques-back kick), and a 5' or '7 primary hose.
