Dive gear FAQs
What are scuba tanks?
Scuba tanks for containers that are worn on the back of the
diver. They normally contain mostly oxygen and nitrogen. About one percent
of the mixture is gases that are not oxygen or nitrogen. The scuba tank
allows air to flow from the tank to the diver’s mouth to enable
the diver to breathe underwater.
What is a wetsuit?
A wetsuit is a neoprene garment that insulates the body from cold. Hypothermia
is always a danger to divers and the core body temperature must be controlled.
During diving a thin layer of water enters the wetsuit and lodges between
the suit and the diver. This layer warms to body temperature and helps
keep the diver warm.
Does a scuba diver need a knife?
There are two reasons why a diver may need a knife:
• The diver gets wrapped up in kelp or sea weed
• The diver gets caught in a fishing line or fishing net
Under normal circumstances a diver usually does not need a knife. The
exceptions to that are for a commercial diver who may be working close
to fishing lines, straps, kelp, and seaweed.
Does one need to be certified to scuba dive?
One definitely needs to be certified to dive. Certification trains the
diver to be safe and responsible under water. It shows the diver how
to put on equipment and how the equipment functions. Certification training
advises the diver on how to stay out of dangerous situations. It is
next to impossible to rent scuba equipment from a reputable dive shop
without being certified.
