Scuba Diving Communications
is the way people relay messages to each other or the ability to share
information. Oral communication is a very common way of
expression, but there are other ways to communicate. It is imperative in
diving that we have a variety of ways to communicate with others in our
effectively communicate underwater, you must first start before the dive
to learn the many forms of hand and body posture. In some situations,
like technical and cave diving, you can even communicate by touch and
very comprehensive pre-dive discussions and planning, issues can arise
during a dive. Examples include the need to check a partnerís air
supply, to tell them to go a certain direction, crisis situation (like
they have a leak), or to simply signal to see if they are okay. To
end a dive requires one of the most basic of hand signals, the ĎGo
Upí or end the dive hand signal -- the thumbs up.
are many hand signals you could learn, but some are deemed more
important or more appropriate for diving. Hand signals meanings can
vary by agency and area, kind of like the many different oral languages.
As long as you and your dive buddies use the same signals, your
communication efforts will be better than trying to communicate with
someone who has a different 'signal' vocabulary.
can find and learn more about underwater communications and hand signals
from professional divers, online resources, and manuals. You
should learn and coordinate your hand signals with all your dive buddies
as well. We will display multiple video clips for many of the
underwater signals to show you variances in them as well as putting them
to use with other signals.
is not the intention of Dayo Scuba and those that created and
contributed to this page to make you experts in underwater
communications; by merely by viewing this site, but we do hope to
improve and broaden your underwater communications skills. Nothing can
replace practicing underwater communications with your dive partners.
