Although snorkeling on the surface is great to
explore the underwater, if you feel more adventurous, you may want to try skin
diving. Diving deeper below the surface will provide you with better views of
fish, coral and other sea creatures.
The skill to practice diving down safely during
snorkeling, will greatly enhance your snorkeling adventure. There is a sort of
zen to diving deeper below the waves...diving safely below, being immersed in an alien environment
you will suddenly feel as one with your surroundings...trust me it's great.
Besides there is so much to be explored beneath the surface that snorkeling
deeper is worth giving it a try.
An important advice you need to know about skin
diving is that you need to know your limits and be completely relaxed when
underwater. Always remember to limit the depth of your dive to your breathing
capacity.
What you should need to know
about diving deeper
Because water is much denser than air, when you
dive deeper you will quickly become aware that water will exert pressure on your
air bodily spaces. The deeper you descend, the greater the pressure. For every
10 meters, pressure is increased by 1 atmosphere. This means that at a depth of
10 meters, the total pressure exerted on you is one atmosphere of water pressure
and one atmosphere of air pressure. To counter this effect of pressure on your
air bodily spaces you will then need to equalize. If you want to lean more about
equalization techniques, I recommend that you to take a look at our article on
how to equalize. Here you will find useful techniques on how to overcome
underwater pressure.
How to descend effectively
To increase amount of time you can spend
underwater, try taking in 3 to 4 deep rapid breaths before diving. It is
important not to exceed this amount of breaths as it may cause you to have
excessive hyperventilation which could lead to sudden unconsciousness whilst
underwater.

The head first-dive in my opinion is the far
most effective way for getting deeper as it provides you with a great amount of
forward momentum and will help you to get down quickly without expending too
much energy during your skin diving adventure.
Whilst resting at the surface in a horizontal
position bend forward in the middle so that your head faces down toward the sea
bed. Pull your legs straight up out of the water, (just like you are doing a
handstand) with your arms stretched out towards the sea bed.
Maintain this position to immerse into
the water. When your fins are finally below the surface, start to kick with your
feet so that you may descend deeper. Remember to equalize whenever you feel
pressure in your ears.
As you skin dive along underwater, try not to
make rapid movements but instead move slowly in a graceful fashion as this will
allow you to conserve the oxygen in your body. If you relax, you may be
surprised at how long you can comfortably stay underwater.
Ascending back up to the Water’s Surface and Clearing the
Snorkel Tube
When you feel the need to breath during your skin dive,
begin your ascent. It is important that you leave some air in your lungs so that
you will be able to exhale any water out when you surface. During your ascend,
place your hand stretched out towards the surface and tilt you head to look up
so you can get a complete view of the surface
The
advantage of using this snorkeling technique for deep diving is that the opening
of the snorkel barrel is lower than the mouthpiece. Throughout your ascent,
continue to keep your head tilted back while looking at the surface and exhale a
small amount of air into your snorkel. As you ascend, this air will expand,
forcing the water out of the snorkel barrel's opening. As long as you keep
looking upwards towards the surface, the snorkel will remain free of water due
to trapped air inside the barrel.
When you reach the surface, begin exhaling and continue to
exhale until you reach the face down resting position. Although the snorkel
should now be clear of any water, it is important to use airway control and
cautiously take your first breath, in case some water remains in the snorkel.
Before you attempt another skin dive, be sure to rest for
at least a minute or so between dives so that your body can return to its normal
oxygen level. If you should feel in any way, fatigued, dizzy or light headed, it
is best if you discontinue your skin diving and rest until you have recuperated
your energy.
After your skin diving adventure is over, remember to take care of the
equipment. So check out our snorkeling
gear guides on information for
how to maintain your snorkeling equipment after each and every
snorkeling outing.
