scuba diving

Scuba diving is a fun activity. It can be done both personally and professionally. Scuba divers use fins and breathing equipment while diving underwater. Some of the basic equipment used during this activity is given below.

Basic Scuba Diving Equipments :

Alternate air source

This works as a back up for divers. Whenever a diver’s first or primary air source fails, this equipment comes to rescue. It works the same as the primary. It is attached between your chin and rib cage in a triangle. It is usually bright in color.

Buoyancy control device

A BCD is a jacket worn by divers. It controls the buoyancy or their ascent or descent in water. There is a lot of pressure underwater and this jacket helps in keeping you safe.


These are boots with fins specially designed for scuba diving. They are made to keep our feet warm and comfortable in cold water.


It is very important to know the directions underwater. A compass is worn on the wrist that is attached to a watch or dive computer. Digital compasses are designed for diving.


It is an important equipment in scuba diving as it carries your compressed breathing gas that is required underwater for breathing. It is a tank that has almost 3000psi/210bar. Its size is about 90 cubic feet or it may even vary.

Depth gauge

This device tells you how deep you are underwater. It shows depth either in meters or feet.

Dive computer

These computers handle various operations like showing directions using a compass that is attached to it. A depth gauge is also attached to it that shows your depth and dive time. They also tell us the air consumption and the amount left in the tank. Its other functions include showing underwater temperature details and is used as a mask.

Dive knife

A dive knife is not used as a weapon. It is an instrument that is used to free the divers from any kind of entanglement like fishing line. Some divers carry more than one knife. It is carried on the BCD and the leg.


They are attached with boots or booties. They are made up of flat rubber or plastic extensions that help you in swimming easily and faster. They keep us warm and comfortable in cold water. They are of two types- full foot and open heeled.


It is a tube-like structure made of plastic that is attached to the left side of the mask. It helps you to breathe when you are on the surface of the water. Thus helps you in saving the air in the tank.

Weight system

People who are light weighted need artificial weight to sink in water. The weight belt and integrated weights help you to do this.

Underwater vision

It is difficult to see underwater because the refractive index of water is higher than air. This device provides air space in front of the diver’s eye and thus allows you to have a clear vision when underwater.
