"How deep can you
dive?" this is the question most asked by Scuba Diving fanatics. As in any
sport, there are various answers to this question depending on various factors.
One of which is how much experience does the diver have? This is perhaps the
most important factor since depth of diving depends directly related to how
deep a person can go without getting decompressed.
The second factor that
makes a difference is pressure. As divers develop their skills and become more
experienced, they may need to ascend higher to go deeper. Or, their breathing
capacity may increase which would allow them to go deeper. Or personal capacities
to high partial pressurization of inert gas at ambient pressure, usually in air
tanks.
Diving equipment, or
sub-zero level (SV or SD) as it is referred to in scuba gear reviews, comes in
different forms. Usually, people tend to talk about the physical form or
function of an underwater gadget first before discussing its performance under
water conditions. And this is usually where many get confused. If you think the
pressure at sea level is the same as what a diver experiences underwater, then
you are wrong. There are differences in how deep can a diver go and how
buoyancy control is affected.
For starters,
underwater pressure varies according to the water temperature, its composition,
and the geographical location. Deep sea, cold water, and even extremely deep
water can have very low or zero pressures. These conditions, together with the
rate of rock erosion and the rate with which water is resurfaced, can affect
the rate with which divers can dive.
The pressure decreases
gradually, from ten to thirty pounds per square inch at twenty meters and ten
pounds per square foot at forty meters. As the water temperature falls further,
the rate of resurfacing slows down, which leads to a slower rate of
decompression. At one hundred feet and six meters, a diver may be able to dive
to a maximum of eighteen meters and can go no deeper than eighteen meters if he
uses solid compressed buoyancy. Anything less than that may be considered a
standard deep dive.
Once a diver has passed
the minimal safety stop time limits, he may proceed to explore the area
surrounding the dive site. At this point, he should have encountered the first
coral or other organism. He can now proceed to sample the waters and observe
its fauna and flora, since this will determine the nature and depth of the pool
or reef which will dictate the number of dives allowed. Diving equipment, the
regulator and other items are also needed. However, no matter how deep a diver
can go, he is still subject to the same rules and restrictions as any other
diver, including wearing a personal flotation device, maintaining correct
swimming and diving procedures, following the area's diving laws, and remaining
alert at all times.
