Water Pressure
• Descending
— Pressure increases in weight as we go down approximately 1/2 pound for every foot
underwater you descend
— You will need to remember to equalize early and often.
Depth Atmospheres Volume of Air
Surface 1
33 Feet/10 metres 2
66 Feet/20 metres 3
• Ascending
– Pressure decreases as we come to the surface
— What happens when you shake up a soda
bottle and then release the pressure quickly?
Breathe normally at all times and never hold your breath!

Equalizing
• Mask
— To equalize your mask, blow through nose into
mask.
• Ears
— Remember to equalize early, often and gently.
• Sinus
— Self equalize when descending and ascending
unless you have some sort of congestion.
• Problems
— Reverse Block and Lung over expansion problems.
— Never dive when you have a cold or
congestion problems.
— Remember to breathe normally at all
times while scuba diving. NEVER HOLD
YOUR BREATH!

Buoyancy Control
• Proper Weighting
— Too much or to little weight makes it difficult to dive.
• At the surface you must become positively buoyant and not struggle to stay afloat
— Push your power inflator button as soon as you reach the surface.
• Underwater a diver becomes neutrally buoyant to be able to enjoy diving.

Know Your Equipment
• Masks do fill with water, therefore you will learn how to clear
your mask whether you have a purge in your mask or not.
• Regulators make it possible for a person to stay underwater
and enjoy diving. You will learn how to clear your regulator in
the event it should come out of your mouth.
• The submersible pressure gauge monitors the amount of air
in your scuba cylinder at all times. While the depth gauge
indicates or tells you how deep you are.

Know Your Equipment
• To inflate the buoyancy
compensator you use a button
that uses air from your scuba
cylinder to fill the BC.
• To deflate the buoyancy
compensator use another
button that will allow the air
to escape and you will be able
to descend and begin your
dive.
• Floatation at the surface makes it easier for you to wait for your
boat or swim back to your exit point.
• You will become neutrally buoyant during your dive so you will
be able to enjoy the dive.

Safety Rules
• The buddy system is used at all
times while diving. Not only is it
safer, it is more enjoyable to dive
with someone.
• You need to stay with
your Instructor/Dive Leader
during your Try Scuba
Dive. Remember if you
and your buddy wish to dive independent of your
instructor you will need to become certified as an open
water diver.
• Remember to breathe normally
at all times and watch the
amount of air you have in your
scuba cylinder. Make sure that
you let your instructor know
when you are at 1000 psi.

Safety Rules
• You may use many hand signals during your dive. Some of the
standard ones are.
— OK? OK
— I need to share air
— I am low on air
— I am out of air
— Look
— Something is wrong
— Let’s Go Up or Down
— Come here
— I don’t understand
— Check your Air
— Ears OK?
— Stop
• Make sure to inform your instructor if you get tired, cold low
on air or if you are ready to end the dive.
• You will need to wait 24 hours after diving before you fly in
an airplane or drive to a destination that is 1000 feet or more
above sea level.

The Ocean Environment
• To protect the environment you need to make sure you stay
away and off of reefs. Remember it may have taken tens,
hundreds or even thousands of years for a piece of coral to
grow but if you are not careful you can destroy it in seconds.
• Marine animals should be viewed appreciated and admired
but do not touch!

Try Scuba Diving Review
True False If you experience discomfort in your ears while descending, you should slowly ascend until the discomfort is gone and attempt to equalize again.
It is important for your safety to breathe continuously at all times while scuba diving.
The submersible pressure gauge allows you to monitor the air in your scuba cylinder.
You do not need to be within touching distance of your instructor or buddy if you can see them.
Scuba diving is easier and more enjoyable if you maintain neutral buoyancy while submerged.
If you get tired or cold, you should signal your instructor and end the dive.
To dive without the supervision of an instructor you must become a certified scuba diver.
Some animals can sting, bite or cut when touched.
