| Well, I have finally had my first scuba lesson. Over all very interesting. I tell ya one thing first off - I am super tired. I had to swim back and fourth 15 times for the first water test. Now, I don't consider myself a weakling, but I quickly lost major energy after five or six laps. I'm not sure how many laps I actually completed. The instructor headed to the main office while I did the laps. He poked his head in from time to time to make sure I was alright. I think he did this on purpose so I could do all the laps I was able to do and then say, after he came back in, that I completed the 15 laps. I lost count after 10 laps, but I think if I didn't get 15, I sure as heck came close, 13,14, or 15. Treading water for 10 minutes was not much of a problem, I just floated on my back. Anyway, setting up the scuba equipment was no problem at all. I set up my equipment, then took it all apart. I guess the most important thing to remember is to put the first stage dust cover on and not let water in it. Then I set up my equipment again, and set up my instructors equipment. We used small aluminum tanks. I'm not sure the size/volume. They were around 3000psi. I was shocked by how heavy they weighed. Around 40 pounds I think. The weight belt with weights kind of heavy too. Then again, I was completely tired from that 15 lap swim, my arms were aching a little. So maybe next week that tank and weights wont be so heavy for me with my full strength. We sat at the edge of he pool, and slid our arms into the bdc. Getting my arms into the bcd with that heavy tank on was a little challenge. But I found out I had air in my bcd. So deflating it made it easier. I was shocked that you can fill a bcd up very quickly with the low pressure inflator. Also using your longs doesn't take long to fill it up. After I dropped my head under water for the first time I was shocked by so many bubbles from the regulator. I didn't know the bubbles coming out would be so many and so loud too. We went over the usual things, regulator recover and stuff. That was no problem at all. I thought the easiest method of clearing a regulator is simply exhaling into it. But I really like putting it in my mouth first, then pressing the purge button while my tongue blocks of some of the air. My instructor said the problem most people have in the course is clearing a mask. And after doing it a couple of times I completely agree. I had to pull the mask off my face a little to let water in. Then exhale thru my nose to clear it. It was difficult to inhale thru the regulator while exhaling thru my nose, plus felling that water around my eyes. But I did it and my instructor was satisfied. When we finally swam to the deep end I sunk like a stone. I didn't put any air in my bcd. I was a little surprised the tank pulled me down like that. Plus trying to sit on my knees was a little difficult. Then, when I did shoot air in my bcd, a couple of seconds later I shot up. Again, I was shocked you can fill air in your bcd so quickly and it takes you right up. I can see neutral buoyancy is something that tanks time to develop. I was also surprised how much bigger things look. I actually got a little disoriented a few seconds in the deep end. I turned around to face the shallow end, but didn't see it, then turned around again, and didn't see it either. One more turn and I found it. Some what disorienting. Also, the first dive to the deep end I really felt the pressure on my ears. We swam back to the shallow end, then after that I think I equalized the right way and didn't feel much pressure on my ears when I went back to the deep end. But I do have this feeling that I have water stuck in my ears or something. Or my sinuses are giving me trouble. Anyway, before this class, I have been thru the Padi cdrom course so much and have read so many magazines that I thought If I stumbled upon a full set of scuba gear while walking on a beach in the Caribbean, I could put it on, jump in, and go scuba diving as good as any pro without taking any classes. Boy, was I wrong. I had just one thing on my mind when I got home - break open my 18 year old Kentucky bourbon, sit down, and relax. |

As for your ears feeling full, you've probably done the usual to them. You didn't equalize properly: it is a learned skill. Did your instructor not give you any advice in this regard before you went into the water? In any event, the usual thing that happens with new divers is that they don't equalize early enough or often enough and when they do equalize . . .they blow too hard. You must have another lesson or two coming up, yes? Make sure that your ears are OK (not infected) before you continue. |

We sometimes forget what it was like the first time we did this crazy underwater thing. <soapbox> Your comments about buoyancy are especially insightful. As you noticed, neutral buoyancy is both hard to acheive and really, really important. I think one of the issues people have with scuba training today (with the exception of GUE) is that instead of embracing buoyancy as a fundamental skill for diving, they try to teach other skills in a way that removes buoyancy from the equation (i.e., kneeling on the bottom while doing mask clearing exercises). This makes it quicker to get underwater safely, but it ultimately does a disservice to the student who never bothers to learn proper weighting and buoyancy control, but gets a c-card anyway. </soapbox> Thanks for taking the time to write about your experiences. I look forward to reading more. Alan |

What exactly happens when you rupture your ear drum? Is it something you would definitly notice? Like, would you be screaming in paign or something? |

I had to > swim back and fourth 15 times for the first water test. Don't worry about it. You don't need to be able to swim at all to dive. If you surface from a dive and the boat is missing you might find swimming to be a useful skill, but until things go wrong swimming is an unnecessary skill. Even if you do find yourself in the middle of the ocean with no boat in sight, as long as you have a mask and snorkel (fins may be useful, too) you still won't be swimming in the same sense as whatever you did for your laps in the pool. I don't consider myself to be a strong swimmer but I can snorkel for hours with no problem at all. Some people will suggest that you don't need a snorkel when you're diving, and just like the abilty to swim, it isn't something you need when things are going well. > We used small aluminum tanks.

Probably an AL 80, a tank made of aluminum and holding 80 cubic feet (when filled to 3000 psi). Ask next time. > We sat at the edge of he pool, and slid our arms into the bdc.

The second arm is a bit of a PITA. If you point your arms down and back and put them both in as you sit down you may find it easier. > After I dropped my head under water for the first time I was shocked by > so many bubbles from the regulator.

You'll get used to it, and it won't seem as loud later, but that's another reason to get comfortable and stop breathing so much air. > It was difficult to inhale thru the regulator > while exhaling thru my nose, plus felling that water around my eyes. But I > did it and my instructor was satisfied. Plan on doing a lot more of it, including after you finish the class and are doing fun dives. When somebody kicks your mask off you'll be glad for the practice. You'll also be reminded why you shouldn't follow too closely. > When we finally swam to the deep end I sunk like a stone. I didn't put > any air in my bcd. I was a little surprised the tank pulled me down like > that. Properly weighted with a full tank you should have been about 5 pounds heavy at the start. If you were wearing a wetsuit it compressed as you sank making you heavier as you went. Did you get hurt slamming into the bottom? I didn't think so. In deeper water you'll have time to add some air to slow your descent so that you don't crash into the reef. >Then, when I > did shoot air in my bcd, a couple of seconds later I shot up. Again, I was > shocked you can fill air in your bcd so quickly and it takes you right up. Again, a wetsuit would exacerbate the problem on the way up. I think it was one of your questions that got the answer to breathe your way up, and now you know why. When you do add air to the BC you should do it in tiny little bursts with just a short tap on the inflator button. Later you'll have a better idea of how much air you need, and can add more air with a longer push when you need to stop a descent at 75 or 100 feet. When you've gotten neutral at depth you'll want to let air out of the BC before you even start your ascent. Instructors tend to overweight beginners so that they don't shoot to the surface and so they can kneel while doing exercises. In your next class you'll hopefully start working on getting neutral and you'll do fin pivots, where you inhale to pivot up with you fin tips still on the bottom, then exhale to sink back down. > I was also surprised how much bigger things look. That still throws me sometimes. 12 ounce beer bottles look like wine bottles. Things look closer than they are, too.

Since I don't normally have anything else to do with my hands while descending I tend to hold my nose and keep a slight positive pressure down to 60 feet or so. Descending feet first helps if you don't equalize easily. > But I do have this feeling that I have water stuck in my ears > or something. Or my sinuses are giving me trouble. You may well have irritated your sinuses or your ears a bit. If you have a bit of water in your mask and trap a bit in your nose when you equalize it's possible to blow water up your eustachian tubes. That can definitely result in a full feeling that lasts for a couple of days. -- Steve The above can be construed as personal opinion in the absence of a reasonable belief that it was intended as a statement of fact.

Unfortunately, I do know what it feels like to blow too hard when learning how to dive. I do know how it feels to have a nasty ear infection from improper equalizing. Unfortunately, I also know how it feels to have a reverse block. As Steve was telling you, there's a point at which one has to decide to endure the pain and ascend anyway. Fortunately for me, that *very* painful reverse block cleared itself and I was able to ascend pain free. I hope to never experience that again. > > |

It's possible to rupture an eardrum and not even know it, but it's extremely unlikely that would happen while diving. The not noticing part, that is; rupturing an eardrum is certainly a possibility. Even worse, you can rupture the round window in your middle ear. A ruptured eardrum can heal leaving no permanent damage, but a ruptured round window is likely to leave you with permanent damage. Damaging your inner ear is something you would most likely do by making a valsalva too forcefully. Not equalizing is your best net for rupturing an eardrum, but it's more likely to happen while ascending. When you descend the pain from not equalizing would probably clue you in, but if you are unable to equalize while ascending running out of air will allow you to put up with the pain as the lesser of two evils. Go back to your Cd-rom and review all the stuff about equalizing and ears. -- Steve The above can be construed as personal opinion in the absence of a reasonable belief that it was intended as a statement of fact.
