Diving Schools

Diving schools are places you can go to learn the basics of scuba diving. Many states require that a prospective diver attend enough classes to be able to pass an exam that features both a written and skills portion. Those that complete the test are accredited divers. It’s similar to the process for learning to drive.

Diving schools are also the best place to learn how to do technical diving. Technical diving is any type of diving that presents special hazards beyond the norm for a diver. Some common hazards are presented by enclosures (either caves or wrecks), by ice diving, and by extremely deep diving. In the case of ice or an enclosure, it’s impossible to directly ascend to the surface, which means a diver has to be able to keep their head in case of emergency.

Extremely deep diving offers its own set of challenges. For starters, past about 100 meters you cannot use a traditional diving air mix, or you will succumb to nitrogen toxicity. That occurs when the nitrogen enters the body at such a high pressure that it can begin to interfere with the normal cell functions such as respiration or combustion. A diving school will teach you how to switch air sources mid-dive to avoid this problem.
