I went through the DIRF class with Mike this last weekend. I was the least experienced diver in the class, by far. The class was the most useful learning experience in the shortest amount of time that I have ever been through, not just in diving, but in my whole life.
"Sobering" and "humbling" are two words that spring immediately to mind to describe the experience, but other words are "respect," "gratitude" and "determination."
To watch myself on video utterly unable to maintain proper attitude in the water for 10 seconds in row while attempting to execute what should be simple propulsion skills like a frog kick, was both sobering and humbling. But, while Andrew's criticism of my deficiencies was direct and unequivocal, it was not in any sense brutal or demeaning. As we spent the evening after the first set of dives reviewing the video of our underwater exploits, Andrew paused and reversed the video, pointed out what each diver was doing right, and what each diver was doing wrong. And he didn't just say it. He showed us. He cleared a table, laid down on it, and demonstrated exactly what he wanted. Then he took some of the divers, like me, and put us on the table, right in the middle on the video review, and showed us exactly what we should be doing and how to do it. This, by the way, was after he had spent the evening before, among other things, doing exactly the same types of demonstrations on the floor, on a stool and on a table. And, it was after we had all spent time the morning before these dives, laying on tarps practicing these same kicks, with the instructors first demonstrating, then moving from diver to diver helping each of us to try to get the muscle memory of how to do it.
The instructors are intelligent, articulate, and phenomenally skilled. They could be doing anything in diving, but they take the time, week after week, to get in the water and try to teach yet another crew of sloppy divers what we all should have learned the first minute we got in the water. I have enormous respect for their skill, their knowledge, and their devotion to improving our sport. I also have deep respect for the people in the class like Mike who have had hundreds of dives, are obviously superior divers to just about everyone in the water, and still are determined to be better. I am grateful for the experience, because even though I'm a mess in the water, I now know what I should be doing to improve, and I have a road map of how to get there. Like Mike, one of my first reactions was to question whether I should quit pretending I am a diver, chuck it in as a bad job, and go work on my golf game. Now, 24 hours after the class is over, I'm just determined to practice what I learned and be the best diver I can be.
Some observations:
The skills we had such trouble with are basic skills that EVERYONE should be able to do proficiently as part of basic training and certification as a diver. Of course, NO ONE gets this training through the conventional agencies. Every agency wants to crank divers through the certification process as quickly and painlessly as possible, both for the divers and for the instructors. The fastest and simplest thing seems be to teach people on their knees, in a little campfire circle on the platform or pool bottom. Conventional training is anchored to a fixed, shallow floor. How does this prepare a diver for an out of air situation or a lost mask when the floor is 100 or 500 or 1000 feet below? I think I had a better OW class than most, but we did not spend one minute talking about, let alone practicing, remaining nuetrally bouyant in the water column, or how to move in an efficient horizontal attitude through the water instead of a drag-inducing vertical attitude. This should be a rock-bottom basic skill, not an issue for new divers to sort out on their own later, if ever.
These are not lofty goals that only the elite can reach. GUE teaches the exact same skills we learned in the DIRF class to ordinary off-the-street neophytes (pretty much like me) as part of their OW class. These student are taught that they CANNOT touch the bottom of the pool. They are taught to perform all the skills horizontally, without losing bouyancy, in the controlled environment of a pool, under the supervision of instructors. It is NOT too much to handle either for the students or the instructors. These ordinary students get out of their OW class looking like elite divers compared to all the rest of us. Every new diver should be taught this way. It can be done.
To answer some questions:
What skills are taught? This is in incomplete summary:
Attitude in the water. Why a horizontal attitude is important. How to acheive and maintain a horizontal attitude. How to tilt around your center of gravity to a head up or head down position.
Movement in the water. Why certain propulsion techniques are better than others, which techniques are appropriate in which environments. How of perform different kicks, such as frog kick, modified frog kick, modified flutter kick. How to reverse, how to rotate over a point, and why you might want to. Why you should not use your hands to move yourself underwater.
Bouyancy. Why you need to control your bouyancy. How to control your bouyancy.
Basic 4 skills. Regulator removal and replacement. Switching from the primary to the backup regulator and back. Flood and clear mask. Mask removal and replacement (with eyes closed to simulate a zero visibilty situation). All skills to be performed horizontally, without losing bouyancy control.
Safety drills. Out of air drills. Donation of primary regulator, switch to backup, control of out of air diver and gas supply, buddy air share while swimming, controlled ascent while air sharing. All to be performed horizontally, without losing bouyancy control.
Predive Planning and Procedures. Team equipment check while dry and in the water. Team dive planning- scenario, air supply, depth, distance, duration, decompression.
Valve drills. Open and close all valves underwater, maintaining proper attitude and bouyancy. Done for both single and double tanks.
Situational awareness. Understand and manage your equipment, environment and team. Know where you are, what you are doing, what is around you, what might go wrong, and what you will do when it does. How to swim with a buddy or group of buddies, maintaining constant communication, either actively or passively. How to follow a line. How to find a lost line. How to prioritize tasks in an emergency.
Equipment. How to fit harness and backplate. Hose routing and management. Hose lengths. Proper placement of equipment. Why, as opposed to whim and caprice, DIR equipment is configured the way it is.
Gas usage planning. Rock bottom and turn pressure tank psi for different size tanks, at different depths, under various dive conditions.
DIR philosophy. Why DIR is the way it is. Why it works. Why various alternatives are unsafe, or less efficient.
Another question was asked about where is the fun in going through all this? Of course the only reason we are in this sport is we want to have fun. But watching a body get hauled out of the water is not fun. It's less fun if it's your body. To be competent and confident in the water is the true way to have the most fun. This class will help you have fun.
I'll conclude this by saying thank you to Andrew, Mike and Dan for putting me on the road to being a better diver.
