For centuries, people have tried to explore
the aquatic environment. In past times, their main reason was to gather
food or to salvage some items from rivers, lakes and oceans. Also, young
girls and boys were trained to free dive to gather shellfish and seaweed,
and even sponges from the sea floor.
In modern times, although people still
continue to dive for valuable objects and food, diving's popularity grew
especially in warm vacation destinations. Tourists and diving enthusiasts
skin dive to explore the underwater world. Without any special training
and equipment, they were able to observe the beauty of aquatic
life.
Basically, skin diving is defined as a water
activity wherein swimmers depend on their lung capacity, a diving mask,
snorkel, and fins to move about underwater for several
minutes.
It's an extension of snorkeling, where
a person views the underwater environment from the water
surface.
Skin diving is termed as such
because of the little equipment it requires. Its basic requirements
are only a waterproof mask, fins for the feet, and a snorkel. A
snorkel is just a tube about 38 cm long with a mouthpiece on one
end, used for breathing underwater.
The diving mask should allow the skin
divers to see clearly even when underwater. A mask, which completely
encapsulates the nose and eyes to form an air space between the
water and diver’s eyes, is preferred.
Fins, also called flippers, are like
the webbed feet of a duck. These enhance the divers' movements below
the water, and help propel them in a smooth and efficient motion.
All fins have a foot pocket to secure your feet in, and large sheets
of flexible plastic.
Snorkels are also helpful in observing
shallow marine life. As long as one end extends out of the surface,
the diver will be able to breathe normally. However, snorkels
shouldn't be more than 15 inches long since air can't be drawn to
greater depths.
If you want to go deeper into
the water, you have to hold your breath. Since you can’t possibly
live without breathing for hours, you can only stay beneath the
ocean for brief periods, usually about two minutes. Experienced skin
divers, however, are known to stay underwater for several
minutes.
The main difference of between skin
diving and scuba diving is the device used by scuba divers. Scuba
stands for "self-contained underwater-breathing apparatus", which is
basically just a metal tank filled with air. This tank should be
connected to a valve regulator for pressure adjustment so the diver
can breathe comfortably even at greater water pressures.
Also, since scuba diving involves
exploring the water at greater depths, there are other major
considerations. A scuba diver needs a suit to keep him warm enough
while underwater.
Scuba divers also make use of buoyancy
compensators to help them control their position while underwater. A
diver just controls the amount of air in these buoyancy compensators
to adjust their overall buoyancy.
Of course, there are several
pressure related injuries that a scuba diver is exposed to.
Ascending or descending too quickly causing significant rapid
changes in the pressure difference between a diver’s body and his
surroundings may be fatal. That’s why, scuba divers need to go
through specialized training to be able to stay safe and remain
alive even when more than a hundred feet below
water.
That's basically the difference between
scuba diving and skin diving. When you scuba dive, you are largely
dependent on your diving gear for survival. Skin diving on the other
hand is a simpler form of exploring the underwater environment,
that’s probably what makes it very popular. As mentioned, you only
need to rely on your own swimming prowess. You won’t need to pay for
any expensive special breathing equipment.
So if you plan to stay at greater
depths for a longer period of time, you can take some scuba diving
lessons. Scuba diving is mostly beneficial for those who wish to
study and collect date on marine environments.
Skin diving is mostly used for food
gathering underwater. In some parts of the Caribbean, it's illegal
to catch lobsters using any scuba equipment, thus, those who are
good in skin make hundreds of dives each day to collect
lobsters.
