What Is a Deep Sea Diver?
Deep sea divers swim deep into a body of water using an apparatus for breathing and remain submerged for extended periods of time. Deep sea divers are also known as commercial divers; they are not diving for fun and enjoyment, but for a purpose.

Reasons to Deep Sea Dive

Deep sea divers may dive for commercial, military or industrial reasons. They may inspect and repair bridges, boats and other structures that are submerged, or search for sunken ships with possible hidden treasures. Some may fish for coral, pearls and sponges. Deep sea divers are used in the military for reconnaissance and even sabotage.

Equipment for Deep Sea Diving

Diving suits are waterproof suits made of canvas and rubber. The hands are free, with the suit sealed at the wrists with heavy rubber bands. Boots that weigh around 40 pounds are worn and weights are attached to the upper torso to help maintain equilibrium. A metal helmet is worn on the head; it has two sides and a front window.

How to Deep Sea Divers Breathe?

A pipe attached to the deep sea diver's helmet connects him to his source of air. The pipe is constructed of non-collapsible material.


Hypothermia, circulatory or respiratory problems (not to mention possible drowning) are just some hazards deep sea divers face. The work a deep sea diver is asked to perform may be hazardous in itself. Lifelines are attached to deep sea divers so they can be hauled to the surface if a problem arises.

Decompression Sickness

Decompression sickness can occur if a diver ascends too quickly to the surface from a great depth. Commonly known as "the bends," decompression sickness causes a variety of problems and could result in death. All-steel suits, a special mixture of gases and guidelines on the correct rate of ascent can prevent decompression sickness.
