Essential Scuba Diving Equipment To Know

Scuba diving is an activity that consists of staying underwater, either free-diving in
the case of free-diving or spearfishing or breathing a compressed gas as part of
scuba diving practice.

Diving equipment
Underwater diving requires specific equipment which may vary depending on the
type of activity.
The common equipment consists of a mask allowing vision underwater, a snorkel for
surface breathing, fins for propulsion and stabilization, a more or less thick wetsuit to
protect against the cold, and ballast.
For the practice of hunting, a crossbow or underwater rifle will be necessary as well
as a knife or dagger. In many countries, it is forbidden to practice scuba hunting.
Regarding the practice in scuba, the equipment is more substantial.
It requires the use of a scuba tank (or block) containing a compressed gas (most of
the time air), and a regulator to allow breathing at ambient pressure. The inflatable
lifejacket or buoyancy or stab allows the diver to carry the bottle in the back
comfortably and stabilizing whatever the depth by injecting air through the inflator
and the live system connected to the pressure regulator.
Additional instruments may be recommended in order to manage the activity in
complete safety:
 The manometer to control the pressure of the bottle and therefore, its
autonomy.
 The dive computer to know the depth, the dive time and the calculation of
decompression stops.
 The lighting underwater to explore and observe wildlife and flora.
 The underwater camera and its housing to immortalize your underwater
experiences.
Diving can be practised professionally:
In the context of underwater work, the equipment will be adapted to the requirements
of the task at hand. The diver can use a face mask and a communication system. A
specific gas can be breathed depending on the time spent underwater (nitrox) or
depending on the depth (trimix). Technological progress sees the emergence of
drones for foresight or pre-dive expertise.
