Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater for recreation, commercial or industrial reasons. Unlike early diving, which relied exclusively on air pumped from the surface, scuba divers carry their own source of breathing gas allowing them greater freedom than with an air line. Both surface supplied and scuba diving allow divers to stay underwater significantly longer than with breath holding techniques as used in snorkeling and free diving.
While not an actual scuba certification, during the discover scuba diving experience you will learn how to use scuba equipment in shallow water, and get a quick and easy introduction to what it takes to explore the underwater world. This can be done in the pool during an open water class or at the ocean inconjuction with a dive trip. Cost varies depending on your situation and desires. The fun part there is nothing like breathing underwater for the very first time. It takes a little getting used to after all, human beings weren’t designed to do that but after a few minutes of awestruck wonder, most participants realize how easy scuba diving really is.
The biggest challenge instructors have with the discover scuba diving program is not coaxing participants into the water, but coaxing them out when the program is over. The fun part? It’s all fun! Plus, you can get credit! If your discover scuba diving program includes an actual scuba dive in open water, your experience may count toward PADI Scuba diver or open water diver certification, putting you a step ahead of the game when you decide to go for it.

Scuba diving is heavily reliant on technology to be successful, and the first development of the idea of scuba was developed by Alexander Lodygin many years before the term appeared. The first commercially successful scuba sets were the aqualung open-circuit units developed by Emile Gagnan and Jacques Yves Cousteau, in which compressed gas is inhaled from a tank and then exhaled into the water, and the descendants of these systems are still the most popular units today.
Scuba diving may be performed for a number of reasons, both personal and professional. Most people being though recreational diving, which is performed purely for enjoyment and has a number of distinct technical disciplines to increase interest underwater, such as cave diving, wreck diving, ice diving and deep diving. Other specialist areas of diving include military diving, with a long history of military frogmen in various roles. They can perform roles including direct combat, infiltration behind enemy lines, pacing mines or using a manned torpedo, bomb disposal or engineering operations.
