Scuba diving is very much a black and white world in terms of the laws and rules one must abide by. It comes down to clear-cut physics. If the laws are broken, severe penalties are exacted, including paralysis or even death.
Scuba Diving is a hobby that is generally misunderstood by the public. Many people have this picture in their minds of brazen divers searching for sunken treasure who get attacked by sharks and have to defend themselves with their diving knives. On their way up, they ascend too rapidly, which gives them the bends and their blood starts to fizz like a bottle of soda that's been shaken up. This picture is rather inaccurate. In fact, nothing could be further from the truth. Scuba diving is a very safe sport that results in fewer injuries than bicycling or roller skating in any given year. Diving knives are rather boring tools that are put to more use as levers to pry shells off of objects or to signal to your dive buddy than as a defense from dangerous ocean creatures and the bends can be avoided by any properly trained diver who knows his limits and plans correctly. A scuba diver must be certified by an accrediting agency before they are allowed to rent dive equipment or use a dive agency's facilities. In my case this certification involved several days of classroom work, three days of pool drills and five open water dives. This training gave me all the needed information to avoid the common dangers of scuba diving and deal with emergency situations. My certification agency was SSI (Scuba Schools International) and I've included a link to there homepage here at the bottom of mine. Hopefully, this site will be able to give you a much clearer picture of what scuba diving is truly like and clear up any misconceptions you may have about what really goes into a scuba dive.
