So last night marked the wonderful return to class, 2 chapters to review, my eRPDml to learn how to use (don't worry I had no idea what it was either... lol), 2 quizzes to take and all that before getting into the water to try out all the new skills. Soo much work.... so little time! Of course we got it all done and under Virpi's amazing instruction, I even feel confident that I know what I am doing.
I have, however, come to the conclusion that they have this course organized so that all the easy brain (my strong suit) and scary physical stuff comes at the beginning and the scary brain and not so difficult physical stuff comes last. Here's why, in week one, classes 1 and 2, I managed to pull off 10/10 on both my quizzes, nailed all my Chapter Reviews and felt really good about the knowledge component (I even participated in class... imagine me talking.... never... lol). But when it came to the physical side, I was a lost cause... struggling and spitting and waiting for a priest to read me my last rights...lol. (For more on that read through "Fitness... I don't need no stinkin' fitness" and If it ain't broke don't fix it.... and from SORTED to super STARS.) So now we have had a week off, I even forced myself to go and redo the Fitness Test (yes.. without dying, although I think the life guards at Sungod were waiting for me to go under a few times,) and now we are back and we were to have the book finished and chapter 3 & 4 Chapter Reviews completed (some people didn't do their homework... tisk tisk..) now it was time to review, discuss and then take our quizzes. For the most part I did ok, most of my Chapter Review questions were done, couldn't finish the last of Review 4 on the eRDPml (I'll explain that in a second,) and scored a 9/10 on my quiz... I know there goes my 4.0 GPA, I placed the wrong number in the wrong order... I knew the right answer, just put it down wrong.... BAH. So here is the scary brainy stuff I was referring to, in chapter 1 we learned about buoyancy, atmospheres, and equipment, in chapter 2 we moved on to seeing and hearing underwater, more on equipment and working with your buddy. Now we move on to chapters 3 and 4 where we learn about contaminated air, nitrogen narcosis, exhaustion, currents, tides, animal attacks and panicking divers.... at this point we have a classroom of panicking divers... ok, it might have just been me, but I just spent a week off, making sure I was working on my fitness which I thought was going to be the death of me, only to review all of the other ways I could die... yeah me!... lol. So, we review all the questions in chapter 3, take our quiz (yes the one I only got 9/10 on) and proceed to chapter 4. Chapter 4, as mentioned, includes more on all the ways to hurt yourself.. lol, including your pressure groups and understanding how these affect the amount of nitrogen in your body. For this we refer to an RDP (recreational dive planner) or in our case, an eRDPml which, if I understand correctly, stands for Electronic Multi-Level Recreational Dive Planner (don't ask me why the ml comes last, it just does). The eRDPml allows you to enter your dive information (is this your first dive of the day?, how deep are you going, how long will you be there, etc) and then will tell you what pressure group you are in, starting with A and ending in dead... I mean Z. You can then use this letter to plan for additional dives for the day to ensure you do not exceed you maximum NDL (no decompression limit.) You see how this starts to get scary... I'm having trouble even figuring out how to even use the eRDPml, never mind wrapping my head around the fact that this is not something you want to make mistakes with and add to that the fact that the system is built for the "average" person (whoever he or she is) and differs from person to person, often based on weight... yeah me! Time to lose all the extra pounds I've been carrying around. We review, and again thanks to Virpi's amazing abilities as a teacher, she breaks it down simple, and eventually gets me and my classmates through using the eRDPml and actually to the point where we were comfortable.... now off to the pool.
For anyone who has ever piloted a boat, then shut off the engine and tried to stop, you'll understand the humor behind hearing a captain say "Full Stop" or "All Engines, Full Stop" and know what it feels like to continue to drift without the ability to make a hard stop. This is very similar in diving, or at least my diving, water is nothing like a road, if you get yourself moving too quickly (up or down), it becomes difficult to stop... at least under control. So our goal for last night was to realize neutral buoyancy... for anyone who doesn't know what neutral buoyancy is, picture it this way, a balloon in water will float, it is positively buoyant, a rock (or me at times.. lol) will sink, because we are negatively buoyant, but a fish that sits perfectly still in the water neither rising nor sinking, without swimming is neutrally buoyant. It is a complex thing to think about sometimes, but the coolest thing to experience, much like being in outer space, you just sit there. To achieve this you must learn breath control. You ensure you are adequately weighted, with just enough air in your BCD and from there you just breathe... sounds simple... it's not. Inhale too much, and off to the surface you go... exhale too much and prepare to meet the bottom. This is where the "Full stop" concept comes in, if you are not careful, and inhale too much and don't exhale soon enough, you start to the surface and despite exhaling it is difficult to stop the motion, the same is true in reverse, if you exhale too much and don't inhale soon enough you start your decent and often it is too late to stop yourself from dropping to the bottom... this is a scary concept when you think about walls with 200 + foot drops below you and the problems with rising to the surface too fast .. you never want to lose control.. ever. But once you have the concept and have practiced achieving this in a few different ways, there is little else cooler than sitting weightless in the water watching your classmates complete their skill tests as you sit, doing nothing, resting only on water, open space above and below you. I was fortunate enough to have Matt Mendes, (again another in what seems to be a long line of amazing Dive Masters at Ocean Pro), in the water with us, signaling me to move up or down (ascend or descend) in the water while signaling for me to check and advise on air pressure, forcing me to be in constant control and alert of my gauges, instead of falling off to sleep due to the completely relaxing feeling of being weightless. Once you have this under control, and never one to want you to get too relaxed, PADI requires you learn how to breathe off a failed regulator... great... more things that can go wrong... is it too late to transfer to basket weaving as a hobby... lol. To prepare for this and simulate a failed regulator, understanding of course that almost every time a regulator fails it fails in the open position venting air, you pull one side of the regulator out of your mouth and press the purge valve releasing tons of air and learn to "sip" air from your regulator without getting water in your mouth... it works!... I don't know how, nor do I need to, but it works and it wasn't hard. We finish the pool time with practicing diver assistance, by pulling and pushing our partners back and forth across the pool, of course I had the wonderful assistance of Matt who, once again liking to keep you on your toes, took great delight in pulling me off course during my diver pull, forcing me to right myself and get back on course all without losing my partner who is "injured" in the water... oh the fun... lol.
So the evening ends, we clean up our gear, get it washed, packed and moved to the door, then off to change before loading the gear in the vehicles for our return to the shop. It's on the way back from changing that it happens, words that are almost as great as the day my wife said "I do" and the times my parents said "we're proud of you", Matt looked at me and said, "You're doing really great out there" and just when I thought my day couldn't get better as I am sure I was floating all over again, Virpi echoed the comment in saying,"You're doing great out there, keep it up."
Life has it's defining moments, some are tragic events that we survive, some are memories of accomplishments past, and some are simply the kind words someone shares with you at a crossroad in life when you need to hear the thing everyone likes to hear... "Good Job."
