Scuba diving is more than a sport. It's a science that operationally integrates physics, chemistry, physiology, and oceanography. It's also pretty cool.
Scuba-from the phrase "self-contained underwater breathing apparatus"-refers to a type of diving in which an individual carries his or her own supply of air. This air supply is stored within a steel or aluminum cylinder called a scuba tank. A device called a regulator "taps" the pressurized air and adjusts its flow for breathing.
Scubadiving is not a sport that you can just go and do, you must have some training to be able to dive. If you want to learn to scuba dive, take a PADI (Professional Association of Diving Instructors) Open Water Diver course, the most widely recognized and respected diving certification in the world. Within a few days, you can be enjoying the underwater world.
Not sure if a full-blown course is for you? Take a Discover Scuba Diving program at a PADI Dive Center or Resort and experience what you're missing. Kids are welcome too. There are a variety of fun and exciting programs available for them as well.
