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.

• 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
Eq ua lizing
• 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!
Buo ya n c y Cont r o l
Buoyancy Control • Proper Weighting — Too much or to little weight makes it difficult to dive.
• A t 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.
• U nderwater a diver becomes neutrally buoyant to be able to enjoy diving.
Mo v in g U nd erwat er
Moving Underwater • Streamline Your Body — Kick with your legs straight...like scissors — Keep your arms at your sides

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.
K n o w Yo ur E q uipm ent
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.
Safe t y R ules
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 your during Dive.

the
amount of air you have in your scuba cylinder. Make sure that you let your instructor know when you are at 1000 psi.
Safe t y R ules
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.
Th e O ce an Env ironm ent
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!

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.
