Since the early 20th century, SCUBA diving has gone from an incredibly risky undertaking well out of reach for all but the fabulously wealthy to a relatively safe sport with a rapidly growing participant community.
SCUBA stands for Self-Contained Underwater Breathing Apparatus, so named for the tanks and other gear which divers carry on their backs allowing them to breathe underwater. Although this gear termed “life-support equipment” and a commitment of real training is necessary in order to become safe and proficient enough with it to dive even in a small lake or quarry, technological advancements and improvements in science and engineering have enabled longer times underwater, deeper dives, and reduced danger in this exhilarating activity enjoyed by athletes and nature lovers.
Having originally been popularized by Jacques-Yves Cousteau and Emile Gagnan, who built the Aqualung (a name still used in Britain to describe Scuba equipment today), Scuba is now enjoyed by millions of people worldwide ranging from locations as temperate tropical waters to under-ice sub-arctic diving for scientific purposes or by adventure seekers.
Many people are unaware of the length of time necessary to attain Scuba proficiency and certification – in the United States, the two major certification bodies are National Association of Underwater Instructors (NAUI) and Professional Association of Dive Instructors (PADI). Depending on the course, new divers can get certified in as little as three to four days of actual instruction – since the courses are based on performance standards and not on hours of instruction, this number can be higher or lower. Also, if a diver wishes to do more technical and dangerous dives or to use more advanced equipment, more training would be necessary in order to ensure safety.
Anyone who enjoys vacations to tropical areas or who appreciates nature and enjoys the water can now consider Scuba diving, thanks to the advances mentioned in science and engineering, as well as the establishment of standardized certification and training programs worldwide. If you’ve never considered it, much more information is available online to help you decide if Scuba makes sense for you.
