Diving Information. Information about Scuba Diving





Types of Diving: Recreational Diving The most common type of diving as you do it for fun and leisure Cage Diving Cage Diving involves diving while in a cage, normally for Shark encounters. It can be very thrilling and one-of-a-kind experience. Cave Diving diving into submerged caves. This can be extremely interesting and exciting. It can be a slightly more dangerous form of Diving (depending on the wreck) and can require additional technical skills. Drift Diving Is basically like 'going with the flow' The diver is moved by the current. Can be an extremely effective way of diving (reduced air consumption), but care is needed as you normally finish your dive in a different location from your start. Night Diving Seeing the nocturnal marine animals alone will surely make the night dive worthwhile. Predators are most active during the night, Night Diving is slightly more risky than when you are diving during the day., due to reduced visibility. Wreck Diving Wreck Diving involves exploring sunken wrecks . This is often done as part of recreational diving, but is also very useful in archaeological researches. It can be a slightly more dangerous form of Diving (depending on the wreck) and can require additional technical skills. Professional Diving, Divers are paid to dive This can include working as a divemaster/instructor in a Dive centre, Media Diving, underwater photography, Scientific Diving, Military Diving, Police Diving, and Commercial Diving (construction of underwater structures, engineering, surveys, underwater salvage, maintenance of fish farms etc

Scuba Diving:
What is it?
Diving Dictionary!
Types of Diving

Scuba diving is basically swimming underwater with a self-contained underwater-breathing apparatus (scuba), to allow you to breathe and stay underwater for extended periods.

Scuba gear was invented by Jacques-Yves Cousteau and Émile Gagnan in 1943.
What is Scuba? The word SCUBA stands for Self - Contained Underwater Breathing Apparatus.

Diving Dictionary!

ACTUAL BOTTOM TIME
The total time in minutes from the beginning of descent until the beginning of ascent

ANOXIA
Lack of oxygen in tissues to support normal activities. Brain cells can be damaged when there is too low oxygen present in the blood.

BAROTRAUMAS
A state brought about by the difference in pressure between air spaces inside the body and its surrounding environment. This health risk usually damages the eyes, lungs, skin, ear, and the sinuses

BUDDY SYSTEM
Where you ‘pair’ off (or sometimes threes) with another diver to keep an eye on each other when diving. Is commonly practiced so that Divers can give assistance to each other, especially in case help or rescue is necessary.

BUOYANCY
Is an upward force on something that is immersed in a liquid or gas. It enables an object to float or make it look like it is lighter.

BUOYANCY COMPENSATOR (DEVICE)
Commonly called a BC, or BCD. Is used by Scuba Divers to stay at a certain depth and to control Buoyancy during descent and ascent

CERTIFICATION CARD
Commonly called a ‘c-card’. Used to show proof of completed diver training and evidence of experience.

CPR
Cardiopulmonary Resuscitation. It is an emergency First Aid which is done on an unconscious person whose pulse and breathing cannot be found.

DECOMPRESSION BUOY
Also called as Surface Marker Buoy. A surface tool used by Divers to mark their position while at a Decompression Stop.

DECOMPRESSION SICKNESS
Commonly called the ‘bends’. It is caused by the formation of nitrogen bubbles in the blood as well as in the tissues of the body.

DECOMPRESSION STOP
Is a period of time when the Diver stays in shallower water in order to get rid of inert gases absorbed by the body during the dive and avoid Decompression sickness.

DIVE COMPUTER
An electronic device used in determining important diving information such as the current depth, maximum depth reached, dive time, time for no-stop dive, and water temperature

DIVE FLAG
Flag used by a boat to indicate that it has 'divers down' diving

DYE MARKERS
Bright-coloured water dyes used as a surface tool. Dye Markers are basically used to increase the visibility of Divers from the air especially in the case of emergency

HYPOXIA
Occurs when the body or part of the body is not provided with sufficient oxygen

LOG BOOK
List of the dives a diver has recorded for proof of experience

NITROGEN NARCOSIS
Occurs when there is a higher concentration of nitrogen dissolved in the blood. For more

OPEN CIRCUIT SCUBA
An apparatus used in recreational diving in which exhaled air is expelled as bubbles into the water.

OXYGEN TOXICITY
Occurs when the Diver is breathing oxygen with a high partial pressure for a considerable period of time..

PADI
'Professional Association of Diving Instructors'. PADI is the largest and most well known professional diving group in the world.

RE-BREATHER
Is a type of Scuba set that converts exhaled air to a gas that the Diver can breathe again. More commonly used by the armed forces

RECOMPRESSION CHAMBER
It is a pressure vessel used to treat divers suffering from certain diving disorders such as decompression sickness.

RECREATIONAL DIVING
Is a type of Diving which is done mainly as a leisure activity and for enjoyment. As opposed to employment etc

REEF
An area or ridge of rocks, sand, or coral that rises to or near the surface of a body of water.

REPETITIVE DIVE
A dive made between 10 minutes and twelve hours of a previous dive.

SAFETY STOP
A specific time spent at a set depth for nitrogen off-gassing (ie to decrease the amount of nitrogen in your blood) while ascending. This is to help stop you getting the ‘bends’.

SATURATION DIVING
A dive performed after the body is fully saturated with nitrogen.

SCUBA
Stands for Self-Contained Underwater Breathing Apparatus. This enables Divers to breathe underwater for a considerable period of time.

SHALLOW WATER BLACKOUT
Characterized by sudden unconsciousness caused from hypoxia. This is also called as latent hypoxia.

SINGLE DIVE
A dive performed 12 hours after the last dive.

SKIN DIVING
Diving without the use of scuba equipment, using with snorkel mask and fins/flippers

SNORKEL
Is a hollow, curved tube made of either rubber or plastic with a mouthpiece that enables you to breathe while you are on the water surface with your face down.

SURFACE INTERVAL
This is the time between dives.

SURFACE MARKER BUOY
Is a float with a strong thin line wound around a reel and is attached to the Diver. This buoy makes it possible for the surface boat cover to know where the Divers are.

TINNITUS
Caused by barotraumas in the inner ear and by per lymph fistula. Described as a ringing sound heard by divers and sometimes need surgical repair.

WHISTLES/POWER WHISTLES
A surface tool used by Divers to get the attention of the surface boat cover.

WRECK DIVING
This form of Diving involves exploration of wrecks, particularly shipwrecks.
