Going deep down with diving gears is an adventure underwater


Diving gears include the diving suit and helmet, diving regulator, BCD (buoyancy control device), fins, and snorkel. Diving gears play a very important role in scuba diving and it’s not an exaggeration to say that without them we cannot dive. Although we can do some free diving without any equipment, for recreational scuba divers who want to enjoy their lives more, good quality gears are necessary. We also recommend Unitex wetsuits for those who like winter scuba diving.

Diving gears Helmets and their history

The history of the modern diving helmet is closely linked with helmets used by workers at hazardous tasks in mines and at the construction of tunnels. The oldest known helmets were made by the ancient Egyptians. They covered only the head and upper torso with a heavy, rigid leather hood, with glass to let light in and small slits for vision.

The earliest helmets had a bag placed below them to increase their volume and help the diver keep his mouth above water or allow him to breathe out inside the suit if necessary.

Helmets used by early American pearl divers were made of metal but they found that these restricted their peripheral vision so they switched to lighter-weight leather helmets with windows cut into them; examples from around 1900 can be seen in marine archaeology museums today (including helmet diving).

Diving and Diving gears

They can be divided into three categories: surface-supplied diving, self-contained underwater breathing apparatus (scuba), and atmospheric diving suits.

Surface-supplied diving

This kind of diving is supplied with air from the surface through an umbilical line that carries pressurized air for breathing and communications and hot water or electrical power for heating if necessary. A surface air supply system includes a compressor that provides high-pressure gas to storage tanks on the dive boat, scoops that bring compressed air down from those storage tanks to the divers at depth, and hoses that deliver air from the scoops to each diver. The most commonly used scuba sets are open-circuit scuba, semi-closed circuit scuba, closed-circuit scuba.

Self-contained underwater breathing apparatus (scuba)

Scuba is a common term for self-contained diving gear that allows the diver to breathe underwater without relying on surface-supplied equipment. Scuba equipment typically consists of an oxygen tank containing gas under pressure, a pressure regulator valve that reduces high pressure from the tank to a usable/reliable lower pressure and then directs the gas to the mask or mouthpiece, diving regulator, submersible pressure gauge container, buoyancy control device(BCD), HP hose line with inflator mechanism used for depth control and propulsion management by finning or use of arms only in a horizontal position, depth pressure gauge(DPG)and an emergency release to inflate the buoyancy control device.

Atmospheric diving suit

It is a type of armored suit that protects the diver from the underwater environment. It also provides means for breathing while on-site or in transit by providing an air supply independent of surface supply, which may provide some safety advantages over scuba. Diving suits designed for surface-supplied use are usually considered ‘hard suits’ whereas atmospheric diving suits are ‘soft suits’. Atmospheric diving suits have their own codes based on similar designs even though they would not strictly qualify as hard suit systems. These types of suits were developed for very deep dives during oil exploration and had a number of features in common.
