PADI OPEN WATER UPDATED SETS TEST QUESTIONS
AND SOLUTIONS GUARANTEE A+
✔✔My sunglasses case falls out of my pocket into the water, but fortunately, it floats so
I retrieve it. I would say my sunglasses case is ________ buoyant. - ✔✔positively

✔✔Salt water causes more buoyancy than fresh water because it is less dense and
weighs less.
a. True
b. False - ✔✔b. False
Salt water causes more buoyancy because it is more dense and weighs more;
buoyancy results from the weight of the water displaced

✔✔To control my buoyancy, normally I will use my weight system and my ________ -
✔✔BCD

✔✔When I descend, my buoyancy tends to ________. When I ascend, it tends to
________. - ✔✔decrease, increase

✔✔Underwater, when I inhale, my buoyancy ________ - ✔✔increases slightly

✔✔It is important to master buoyancy control because it affects almost everything I do
in and underwater.
a. True
b. False - ✔✔a. True

✔✔In recreational diving, the buddy system means diving with another diver or divers in
a team that provides assistance and safety benefits.
a. True
b. False - ✔✔a. True

✔✔Overall benefits of the buddy system include ________ - ✔✔practicality, safety and
fun

✔✔The three most important considerations in choosing scuba equipment are
suitability, fit and ________ - ✔✔comfort

✔✔Getting the service my gear needs may be a consideration when choosing
equipment.
a. True
b. False - ✔✔a. True

✔✔Before each use, I should ________ my equipment. - ✔✔inspect

,✔✔I need a mask because ________ - ✔✔my eyes must be in air to focus

✔✔My mask encloses my nose so I can ________ - ✔✔equalize the mask

✔✔From among masks that fit me, I should choose a mask that fits as far away from my
face as possible.
a. True
b. False - ✔✔b. False
Choose a low profile that sits as close to your face as possible

✔✔I want to adjust my mask so the strap rests ________ - ✔✔above my ears, over the
crown of my head

✔✔Snorkels are standard equipment for scuba diving because they allow me to breathe
with my face in the water, or in rough conditions, without wasting my scuba air,
especially when I have little scuba air remaining.
a. True
b. False - ✔✔a. True

✔✔Some scuba divers prefer a snorkel with a flexible lower portion so it drops out of the
way when not in use.
a. True
b. False - ✔✔a. True

✔✔When my snorkel is in my mouth, the tip should be ________ - ✔✔over the crown of
my head

✔✔Fins provide a large surface area so my legs can push against the water effectively.
a. True
b. False - ✔✔a. True

✔✔The two basic fin styles are ________ fins. - ✔✔adjustable and full-foot

✔✔My primary considerations when choosing fins are fit and ________ - ✔✔blade size

✔✔To prepare adjustable fins, I should adjust the straps wearing my wet suit boots.
a. True
b. False - ✔✔a. True

✔✔BCD (Buoyancy Control Device) - ✔✔Holds your kit together and allows you to
adjust buoyancy throughout the dive.

, ✔✔Regulator - ✔✔Delivers breathing air at the surrounding pressure when you inhale
and directs exhaled air into the water

✔✔Cylinder - ✔✔Hold the high-pressure breathing air supplied by your regulator during
the dive.

✔✔Weight System - ✔✔Holds lead weight to counteract the positive buoyancy of your
body and some of your equipment, with a mechanism for dropping some or all the
weight in an emergency.

✔✔Identify the four systems that make up a scuba kit. - ✔✔Cylinder, BCD, Regulator,
Weight System

✔✔There's no real benefit to choosing the components of my scuba kit as an integrated
package.
a. True
b. False - ✔✔b. False
Although the components are generally interchangeable, choosing your scuba kit as a
package helps you best meet your preferences

✔✔Inflatable Bladder - ✔✔very durable bag that you inflate or deflate to change your
buoyancy

✔✔Cylinder band and harness/jacket - ✔✔The bladder integrates with an adjustable
harness that holds the cylinder on your back. The bladder may be entirely behind you,
or wrap partially around your waist and/or over your shoulders. With some systems, you
can interchange harnesses and bladders to accommodate sizing and preferences.

✔✔LPI (low-pressure inflator) mechanism - ✔✔Usually at the end of a large-diameter
hose, the LPI inflates the bladder with air from your cylinder, via the regulator, when you
press a button. Another button allows you to deflate the bladder, or inflate it orally.

✔✔Overpressure/quick exhaust valves - ✔✔to prevent rupturing the bladder due to
overfilling, BCDs have one or more overpressure valves that automatically vent if the
BCD is too full. Some may have "quick dump" valves that let you manually release air,
which is sometimes easier (due to your position in the water) that using the LPI exhaust.

✔✔Shoulder quick release - ✔✔a quick-release buckle on one or both shoulders makes
it easier to get out of your kit

✔✔Buoyancy Capacity - ✔✔Most BCDs cover a wide range of diving circumstances.
Your BCD should have ample buoyancy to easily float you and all your equipment at the
surface. You sometimes hear the amount of buoyancy called "lift" capacity.
