PADI Deep Diving Practice Study Guide
Test.
What five activities can you enjoy while deep diving? - CORRECT ANSWER 1) Observe aquatic life that
doesn't live in shallower water.
2) Visit wrecks that rest in deeper water.
3) Shoot photographs.
4) Drift effortlessly past deep water reefs.
5) Collect or recover objects that were lost at great depths.
What is the difference between an appropriate and an inappropriate deep dive objective? - CORRECT
ANSWER An appropriate objective will be singular, reasonable, and based on your training, experience,
and dive conditions. An in appropriate objective is one that expects to accomplish too much in one dive
or for nothing more than the "thrill" of facing risk.
What is a recreational "deep dive"? - CORRECT ANSWER 18 meters/60 feet or below, but no deeper than
40 meters/ 130 feet.
What are the four reasons that 30 meters/ 100 feet is recommended as the optimal depth limit for
recreational diving? - CORRECT ANSWER 1) The short no decompression limits and rapid air use makes
dives short.
2) Nitrogen narcosis begins to have at that depth.
3) Dives to that depth are more associated with decompression sickness.
4) It becomes very dim, or completely dark. This makes it hard to see your gauges and what's around
you, and use your equipment.
What five factors should you consider when determining your personal depth limit? - CORRECT ANSWER
1) Environmental conditions.
2) Physical and psychological limitations.
3) Depth of previous dives, surface interval since your last dive, and your pressure group. Check your
computer.
4) Location and distance from medical care.
, 5) The previous factors as they apply to your buddy.
How do you determine whether your equipment is acceptable for deep diving? - CORRECT ANSWER
Regulator-Should be balanced and serviced annually. SPG-Should be serviced annually. Tanks-Should be
71.2 cubic feet or larger. BCD-Check it, and have it serviced as needed. Exposure suits-Choose a suit
based on the deep water temperatures. Alternate air source-Have one and think about a pony bottle.
Gauges-Have a dive computer, or depth gauge and timer, plus a compass. Have them checked for
accuracy annually, or if they're dropped or subjected to any abuse. Surface signaling devices-Use an
audible and/or surface signaling device.
What five pieces of specialized equipment are recommended for deep diving? - CORRECT ANSWER 1)
Reference line
2) Emergency breathing equipment
3) Spare weights
4) Dive Light
5) First aid and emergency oxygen
How do you set up a deep diving support station, with and without using a boat? - CORRECT ANSWER
Set up a float with an anchored line and a weighted 5 meter/15 foot line for suspending your emergency
breathing equipment and spare weights.
What six basic guidelines should you follow when using a dive computer? - CORRECT ANSWER 1) Use the
computer as a no decompression device.
2) You and your buddy should have individual computers.
3) Always follow the computer with the more conservative readout, yours or your buddy's.
4) If your computer fails, follow manufacturers instructions. If there are none, make a normal ascent and
a safety stop.
5) Back up your computer with dive tables.
6) If your group doesn't have computers, let your dive master know that you do.
What are two techniques for maintaining contact with your buddy during a deep dive? - CORRECT
ANSWER Watch each other during ascents and descents. Stay within touching distance of each other
and swim side-by-side just above the bottom. In poor visibility you can use a short "buddy-line" to
maintain contact.
