About Scuba Diving

About Scuba Diving
Scuba diving requires some training and a complicated set of gear. It's a popular sport around the world, and divers can be found wherever there is something worth taking a look at underwater.

Basic Gear

The absolute minimum gear for a scuba diver is an air cylinder (tank), regulator, dive mask and swim fins. Many divers also use a snorkel, wet suit, weight belt or vest, and a buoyancy control device.

Advanced Gear

Technical divers who make very deep dives often bring along multiple air cylinders bridged by a manifold to prolong their dives. Many also use a dive computer to monitor decompression, depth, water temperature and other factors.

Decompression Sickness

The main health hazard for divers is the absorption of too much nitrogen by the blood when the body is under high pressure. When the pressure subsides as the diver returns to the surface, this nitrogen can rapidly come out of the blood in bubbles, leading to anything from mild aches to death.

Basic Training

Most scuba diving organizations teach beginners the equivalent of the Professional Association of Diving Instructors' Open Water basic dive training program. This covers the elementary skills needed for recreational diving, and at the end of the program divers are cleared for dives of up to 60 feet.

Recreational Dive Limits

The safe limit for a recreational diver is generally defined as between 130 and 140 feet. Past this, specialized skills, planning and equipment are required.


While most divers prefer warm waters, enthusiasts dive just about everywhere. The usual points of interest are shipwrecks, reefs and other undersea formations that attract fish.
