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!

mask.

• Ears

• Sinus

— Self equalize when descending and ascending

unless you have some sort of congestion.

— Never dive when you have a cold or

congestion problems.

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.
