00:00:05.000 --> 00:00:07.000
[underwater exhalation]

00:00:11.500 --> 00:00:14.600
Divers need to be able to perform a controlled

00:00:14.600 --> 00:00:18.233
and must be able to slow or stop if they have a
problem clearing their ears or sinuses.

00:00:18.233 --> 00:00:21.266
Not all dives are on the bottom.

00:00:21.266 --> 00:00:23.266
Some dives are mid-water or on a ship's hull.

00:00:23.266 --> 00:00:27.932
if you plan a dive to a certain depth, you should
not exceed that depth or your dive tables will

00:00:28.733 --> 00:00:32.766
In the case of Nitrox you may have a maximum
depth based on what you are breathing.

00:00:35.133 --> 00:00:38.999
Before you make a controlled descent, there are
a few things you need to do.

00:00:39.000 --> 00:00:42.433
Check with your dive buddies and make sure
they are ready to leave surface.

00:00:42.433 --> 00:00:46.766
Get a compass heading on the beach, or your
exit point, as a reference.

00:00:46.766 --> 00:00:52.099
Check your cylinder pressure and then check
your time so you know when your dive starts.

00:00:52.100 --> 00:00:59.866
To make a controlled descent, put your inflator/
deflator high above your left shoulder and vent
air from your BC until you start to descend.

00:00:59.866 --> 00:01:06.099
On the way down, if you need to, You can add
small bursts of air to your BC to control your

00:01:06.100 --> 00:01:11.233
When making a controlled descent we always
keep our feet beneath us so if we need to use
our fins

00:01:11.233 --> 00:01:16.399
to slow or stop our descent because of ear or
sinus issues, we can.

00:01:16.400 --> 00:01:25.233
We only descend as fast as the slowest diver in
the team and we always stay together as buddy
teams when diving.

00:01:25.233 --> 00:01:26.633
That's a controlled descent.
