The most efficient way to approximately measure 800 m underwater is to use kick
cycles to count the distance traveled - Answer -true
Natural navigation does not require you to look back at where you have been and
should never be combined with compass navigation - Answer -False
A compass is non-magnetic and does not interact with manmade objects or magnetic
fields - Answer -False
put the basic natural navigation procedure in the correct order - Answer -1) establish
starting references
2) follow pre-planned general course
3 )move forward from nav aid to nav aid and frequently look back
4) develop a desire to remember
pair navigation equipment with information it provides - Answer -Dive computer:
duration of swimming and vertical position in the water column
compass: bearings and degree markings to plot a path
timing device: duration of swimming
clear mind: concentration of maintaining a bearing and noting natural navigation aids
depth gauge: vertical position in the water column
match cardinal directions with their correct degree values - Answer -South: 180
north: 0
east: 90
west: 270
, put the basic procedure for compass navigation in the correct order - Answer -have a
starting heading and follow a general course
take a bearing on the most distant object you can see for your heading
as you go from point to point mentally note natural navigation items that might aid you
on return
be aware of deviation if you're navigating around wrecks or other ferrous metal objects
As you swim compensate for currents to maintain the bearing
Put the steps of surface positioning or getting a fix in the correct order - Answer -visually
identify two objects that are directly inline with each other
take a bearing on the first pair of objects
write down the objects and the bearing
turn 90 and select two more objects that are directly inline with that bearing
write down the second pair of objects and their bearing
Low visibility when diving can be defined as the inability to identify another diver at a
distance of 3m (10ft) in a horizontal direction - Answer -True
Place summary list in the correct order for the procedures of night diving - Answer -keep
excursions short
monitor instruments and buddy more frequently
if separated cover your light and slowly turn in a circle looking for your buddies light
keep your light beam out of other divers and animals eyes
if your light fails switch to a back up, signal your buddy, and make a controlled ascent
control your anxiety
lights are an obvious requirement for diving at night, but you may not be aware that
several different types are available. The principle requirement is a good ____ dive light.
A smaller ____ light is also useful to make a safe exit in the event your ____ light fails
during the dive. Each diver should have both a ____ and a ____ light - Answer -primary,
backup, primary, primary, backup
