Normally a trainee will be initially overcome with the many facts and figures involved. Of course they are pumped up with excitement and are impatient as well. We do understand the feeling very well, but it is important to be aware of the information you take in and where it comes from. This topic of dependable and trusty information is being confronted by the internet for a number of reasons. Good intentioned people sometimes publish erroneous or misleading information. Just remember to be positive that your resources are from a reliable source.
Making proper adjustments so you are at neutral buoyancy are a must for any diver. But one important point is to take into account your wetsuit and the effects of depth on buoyancy. As you go deeper under the water, your wetsuit will become less buoyant, due to the extra pressure compressing the bubbles. When you are in shallow waters you may feel like you need more weight. For the reasons just mentioned, as you go deeper you will no long feel underweight. Owning your own wetsuit is a good idea, if you plan on doing much diving. Owning your own wetsuit would allow you to learn what happens to buoyancy at certain depths. You will get the same things repeated many times, once you start taking classes, so you can get your PADI certification. Some things that could be life-threatening you will be taught, and you must never forget them. Being underwater could be dangerous to your health, when you have a cold. Congestion can be a big problem with equilibrium underwater, and that’s what usually comes with a cold. A common occurrence, known as “reverse squeeze, happens to people, who dive while on cold medication, as they come up to the surface. Maybe you had a dive planned, but don’t do it if you have a cold.
It is important to equalize in the first portion of your dive and remember to do it intermittently. Divers with experience advocate going through the equalization steps before you enter the water. This will give your ears the familiarity with what is about to take place. But you absolutely should do this once in the water and keep doing it every couple of feet or so. You can avoid ear problems while descending and obviously this is a good thing. You might discover that one of your ears is not equalizing; when this happens, just turn that ear to the surface.
Getting your PADI certification for scuba diving will be just the beginning of hopefully many years of safe and fun exploration under the sea and ocean. Always take your sport very seriously because there are dangers, as you know. So always prepare and follow the rules to avoid the possibility of problems while under water.
