PADI OPEN WATER EXAMS 2026/2027 SCRIPTED
QUESTIONS AND SOLUTIONS GUARANTEE A+
✔✔Why does my mask need to enclose my nose? - ✔✔Because the mask creates an
air space, you need your nose to blow in it to equalize it
✔✔Why do I need a snorkel? - ✔✔It saves your air supply while your face is in the
water
✔✔What are 2 basic fin styles? - ✔✔Full-foot and adjustable strap
✔✔What consists of your scuba kit? - ✔✔Buoyancy control device, regulator, air
cylinder, weight system
✔✔What 5 components make up a BCD? - ✔✔Inflatable bladder, harness/jacket and
cylinder band, low pressure inflator (LPI) mechanism, overpressure/quick dump exhaust
valve, weight system
✔✔inflatable bladder - ✔✔Controls buoyancy
✔✔harness/jacket and cylinder band - ✔✔Holds cylinder on back
✔✔low pressure inflator (LPI) mechanism - ✔✔Inflates bladder with air from your
cylinder with the touch of a button
✔✔overpressure/quick dump exhaust valve - ✔✔Vents air if the bladder is overfilled
✔✔weight system - ✔✔Contain weight pockets that you release and drop in case of
emergency
✔✔What 2 special maintenance considerations do BCDs have? - ✔✔Rinse the inside of
the bladder with fresh water, and store them partially inflated to keep the bladder from
sticking together
✔✔What 5 components make up a regulator? - ✔✔First stage, second stage, alternate
air source, low pressure inflator (LPI) hose, submersible pressure gauge (SPG)
✔✔first stage - ✔✔Supplies air to all the other components, connecting to the cylinder
valve by screw or clamp, reduces cylinder pressure to intermediate pressure (above
surrounding pressure)
✔✔alternate air source - ✔✔An extra second stage you use for sharing air with a buddy
Attaches in triangle area between chin and hips
, ✔✔second stage - ✔✔Reduces pressure to surrounding pressure, delivers air upon
inhalation, vents exhalation
Goes over right shoulder
✔✔low pressure inflator (LPI) hose - ✔✔Supplies air to your BCD inflator
✔✔submersible pressure gauge (SPG) - ✔✔Hose that tells you air pressure remaining
in your cylinder
Goes under left arm
✔✔What is the most important consideration in choosing a regulator? - ✔✔The ease of
breathing
✔✔yoke system - ✔✔Holds first stage to cylinder with a clamp
✔✔DIN system - ✔✔Regulator screws into valve
✔✔What 3 special maintenance considerations do regulators have? - ✔✔Rinse first
stage individually, run water through second stage, have professional overhaul it about
every year
✔✔What 2 components make up a scuba cylinder? - ✔✔The aluminum/steel container
and the valve to control air flow
✔✔What is a burst disk? - ✔✔A safety device that relieves overpressure by rupturing
and releasing air
✔✔What is the most important feature in my weight system? - ✔✔A quick release that
will enable you to float with an uninflated BC
✔✔Why use more than 1 weight system? - ✔✔It will help distribute weight
✔✔trim - ✔✔The orientation and balance of a swimmer in the water - the ideal is
horizontal
✔✔danger/hazard - ✔✔
✔✔okay - ✔✔
✔✔go up/end dive - ✔✔
✔✔something's wrong - ✔✔
✔✔down/descend - ✔✔
