Chapter 3 Flashcards
If you must walk with fins out of the water, you must walk
Backwards or side step
When you kick with fins, your kick must be
Slow, deliberate, and wide
The key to a successful surface dive is to
Get as much of your body out of the water as possible
You blast clear your snorkel by
Exhaling air forcefully as you surface
What method is an alternative technique to clear your snorkel?
Displacement clearing
Standard regulators are made to come over your
Right shoulder
When you test your scuba unit, be sure that your
Primary and back up second stages work and that your BC inflates and deflates properly
When standing on a boat or dock and the water is no more than 2 meters (7 feet) you should
use the grand stride entry
If diving from a small, unstable boat
Use a back roll entry
During a surf entry your BC should be
Not inflated
If you fall during a wading entry…
Crawl toward deeper water on your hands and knees and swim as soon as possible
When do you never stop?
A surf zone or boat exit area
When you clear a mask with a purge valve you tilt your head
Down
When you clear a mask without a purge valve, you tilt your head
Up
You can retrieve your regulator using the
sweep or reach method
You should check your submersible pressure gauge at least every
5 minutes
You should not continue your descent if you cannot
Equalize your ears
Your rate of ascent should not be faster than
9 meters per minute
If you must share air supply with another diver, preferred method is
Contingency Air supply
When you buddy breathe, each diver takes
2 breaths per cycle
The optimal method of knowing that you have air in an emergency is to carry
A contingency air supply
You should dive with your buddy
Side by side
When you are given a hand signal under water you should
Display it distinctly and wait for a response from your buddy
If you wave to someone under water they probably think you are
In distress
When you don your scuba unit in the water using the over the head method, the hose for your second stage should be
Between your arms
When removing your weight belt to either ditch it or hand it out of the water, you should hold the front end of the belt in one hand and pull the belt
Completely away from your body
For your compass to work properly
Hold it level and keep the lubber line aligned with the centerline of your body
You navigate a reciprocal course when you make a what degree turn halfway through your dive?
180
To turn off the air flow from a scuba cylinder turn the knob
Clockwise
Before you can remove the scuba cylinder, you must
Push and hold the purge button to relieve the air pressure in the hoses
