Diving Equipment
There are a lot of pieces of diving equipment that every
diver should know about prior to going on their first dive. This is
why most areas require that prospective divers take classes and become
certified prior to beginning dives on their own. This article will present
the basics of the most essential portions of diving gear.
The most essential portions of your diving equipment are
the pieces that make up your air supply system. This system has three
main parts: the air tanks, the supply line, and the mouthpiece. Air
tanks are made of steel or aluminum and designed to withstand internal
pressures in excess of 100 psi. They are filled with a mixture of pure
gasses to ensure that impurities are not inadvertently delivered to
the body at a high pressure.
Your supply line is designed to take the highly pressurized
gasses in the tanks and deliver them to your mouthpiece at a breathable
pressure. It does this via a set of valves that operate similar to air
locks. The first lock depressurizes the air enough to be safe. The second
lock adjusts it further to the atmospheric pressure that a diver is
at with the aid of a sensor.
Finally, it is delivered to the mouthpiece, which is designed
to allow air to exit, but not enter the system.
Without an air supply system, you would die while scuba diving, which
is why it’s the most important system you bring with you. However
it’s not the only diving equipment you need. Other equipment protects
you from additional hazards that are associated with diving. For instance,
did you know that you can get hypothermia while diving in tropical water?
It’s true!
You see, water is a great conductor of heat, that’s
why we boil things to cook them. However, it can also sap heat away
from a hot object quickly if the water is cold. Even tropical ocean
water is 15 degrees cooler than your body temperature, which may not
seem significant. However if your body temperature dropped 15 degrees,
you would die. When you are immersed head to toe in water, you effectively
begin trying to heat up all the surrounding water to your body temperature,
which in something the size of the ocean is a futile task.
To help prevent that, divers wear wetsuits. These suits
are designed to trap a small layer of water against your skin and allow
your body to heat it. They then form a thermal barrier against the rest
of the ocean, keeping you comfortable as you dive. While you won’t
die in minutes without a wetsuit, you could suffer adverse health effects
if you dove without this handy piece of diving equipment.
Another piece of diving equipment that is more necessary
than many give it credit for is the diving mask. A diving mask protects
your eyes from irritation by the ocean water, and also enhances your
ability to see underwater. The ocean actually acts like a giant fish
eye lens, distorting your peripheral vision. This can cause motion sickness
among other things, and vomiting underwater is not something you should
try.
