Scubadiving offers the divers
unlimited freedom of movement under water because they swim with fins,
minus any heavy equipment. The scuba gear is comparatively inexpensive
and simple to operate and maintain. Scuba diving is currently used for
recreational diving, as well as for conducting underwater tasks for
military, scientific and commercial purposes.
Tip!
It's easy to think that scuba diving is just about going underwater
and enjoying the fish. For most people who scuba dive on an ongoing
basis, there's a lot more to it than that.
Apart from the conventional mask and
fins, a basic scuba set comprises a cylinder of compressed air attached
to a two-stage ""demand regulator."" The purpose of the regulator is to
lower the air pressure from the cylinder and allocate it to the diver as
needed.
Scuba diving is commonly
sub-categorized into two types: open scuba and closed scuba. Open scuba
allows the diver to breathe air from a cylinder or canister, and the
exhaled air goes into the water and rises to the surface as bubbles. An
improvisation of this model, closed scuba allows the diver to reuse the
same gas.
Pursued professionally, as well as a
hobby, scubadiving has been a blessing for scientists and
researchers yearning to explore the underwater world.

To dive safely, divers need to
be able to control their rate of descent and ascent in the water.
Ignoring other forces such as water currents and swimming, the diver's
overall buoyancy determines whether he ascends or descends. Equipment
such as the diving weighting systems, diving suits (Wet, Dry &
Semi-dry suits are used depending on the water temperature) and buoyancy
compensators can be used to adjust the overall buoyancy. When divers
want to remain at constant depth, they try to achieve neutral buoyancy.
This minimizes gas consumption caused by swimming to maintain depth. |
