M4 – The Scuba Gear

The equipment carried by the diver is called an autonomous Scuba Gear, which allows him to evolve autonomously underwater, allowing him a submerged time of permanence that he would never be able to dive into apnea.

This equipment consists primarily of:

A high-pressure tank with a tap.
A tank fixing system.
A regulator.

This very simple set (very heavy in dry but extraordinarily light in water) allows the diver to breathe safely underwater, whatever depth it is.

The diver, when exhaling, releases the air directly into the water, so this equipment is called an “open circuit”. There are also “closed-circuit” and “semi-closed circuit”, in which the expiration is not direct to the water, but passes through a chemical filter that allows to breathe back the unused oxygen, but these equipment are not part of the scope of this course.
