My Naval SCUBA Dive class (06010)

A lot of people ask on how to become a diver, and though I must reiterate that this only a Navy SCUBA class, the advice is the same. Practice and stay in the game. The game is mental, so if you tell yourself you can do it, and really believe it, you can.

To clear any misconception that there may have been, and to prevent anyone from getting hurt, please do not practice negatives in water alone. Holding your breath in water is dangerous, and should not be taken lightly. If you are on compressed air and try this, there could be serious problems. If you are going to practice negatives, please do so in a safe, controlled environment.

For those of you who think this is not a dive class, regardless of length (This class actually took 6 weeks) or actual type of dive (SCUBA), you can just move along. There are is no need to leave nasty comments or tell me how much you disagree. Those comments will not be approved. If you would like to say something useful or ask a question, feel free.

In addition, the soundtrack on here is not the original. Youtube disabled my sound due to copyright laws, so I picked a song that fit the movement the best. It’s not my favorite song, but it works.

There seems to be an influx of accidental diving deaths in the media these past few weeks. An experienced instructor drowned in her own trainining pool, a renowned diver lost his life to the Andrea Doria in Massachusetts, as well as Ashley Mauldin, who’s family lost her on a dive trip in the Bahama’s. If you are a new diver or a seasoned veteran, you should never skip corners on safe diving practices. Below is an outline of common safe diving procedures. By all means, feel free to add your own, but our sport never allows for subtraction.

Scuba diving (“scuba” originally being an acronym for Self Contained Underwater Breathing Apparatus, although now widely considered a word in its own right[1]) is a form of underwater diving in which a diver uses a scuba set to breathe underwater for recreation, commercial or industrial reasons.[2]

Unlike early diving, which relied exclusively on air pumped from the surface, scuba divers carry their own source of breathing gas (usually compressed air),[3] allowing them greater freedom than with an air line. Both surface supplied and scuba diving allow divers to stay underwater significantly longer than with breath-holding techniques as used in snorkelling and free-diving.

According to the purpose of the dive, a diver usually moves underwater by swimfins attached to his feet, but external propulsion can come from an underwater vehicle, or a sled pulled from the surface.

Water normally contains dissolved oxygen from which fish and other aquatic animals extract all their required oxygen as the water flows past their gills. Humans lack gills and do not otherwise have the capacity to breathe underwater unaided by external devices.[3] Some experiments indicate the possibility of filling and ventilating artificially the lungs with a dedicated liquid (Liquid breathing) — this currently has only medical applications.

Early diving experimenters quickly discovered it is not enough simply to supply air in order to breathe comfortably underwater. As one descends, in addition to the normal atmospheric pressure, water exerts increasing pressure on the chest and lungs—approximately 1 bar or 14.7 psi for every 33 feet or 10 meters of depth—so the pressure of the inhaled breath must almost exactly counter the surrounding or ambient pressure to inflate the lungs. It generally becomes difficult to breathe through a tube past three feet under the water.[3]

By always providing the breathing gas at ambient pressure, modern demand valve regulators ensure the diver can inhale and exhale naturally and virtually effortlessly, regardless of depth.

Because the diver’s nose and eyes are covered by a diving mask; the diver cannot breathe in through the nose, except when wearing a full face diving mask. However, inhaling from a regulator’s mouthpiece becomes second nature very quickly.
