Happy bubbles! Is scuba diving for you?

It’s a whole other world down there. Have you thought about scuba diving on your next vacation? Here’s a look at what you need to know before making the plunge.

Swimming in a sea of azure surrounded by coral and exotic creatures is exhilarating and fills the imagination with wonder, but scuba diving is not something you can improvise or learn overnight. It requires preparation, both physical and mental. The risks associated with diving can be serious and even deadly. Scuba is a combination of curiosity, passion and discipline.

If you’re interested in learning, you need to take courses to become certified. If you want to try it on your next vacation, you need to find a school or dive shop endorsed by a reputable association or resort. Considering the dangers involved, taking impromptu lessons from a local is strongly discouraged. It’s just not worth the risk.

Scuba diving is regulated by the PADI (Professional Association of Diving Instructors). It’s a global organization that provides diving courses and internationally recognized certification. They offer courses across Canada.

Like all sports, you need to be healthy and in good physical shape. Some health conditions may prevent you from diving. You mustn’t be obese, have respiratory problems or cardiovascular disease. People who have been diagnosed with epilepsy and asthma are also prohibited from diving. Anyone under the influence of alcohol or drugs should never dive.

You need to love the water and be a decent swimmer. You should be able to swim at least a dozen laps and be able to tread water for 10 minutes.

You can enroll in one of many dive courses offer by PADI. Courses range from beginner’s programs for first timers to instructor development courses for educators and explorers. Beginner's courses will earn you your first certificate (perfect for vacation excursions), while enriched courses, including photography, can help you work towards this generation’s Jacques Cousteau.

A basic scuba course in a pool will usually cost just under $500. These courses include equipment, and combine both theory and practical knowledge training. You’ll learn how to use the equipment, how to plan and execute secure dives, and how to foresee, prevent and manage any safety issues that may arise.

Upon completion of this 21-hour program, you'll receive your PADI card. Both your diving card and your dive logbook will be recognized around the world.

Scuba diving and visiting beautiful and exotic reefs can open up a whole new world for you on your next vacation, so take the appropriate measures to certification.
