Full Face Diving Mask
A full-face diving mask is a type of diving mask that seals the whole of the diver's face from the water and contains a mouthpiece or demand valve that provides the diver with breathing gas. The full face mask has several functions: it lets the diver see clearly underwater, it provides the diver's face with some protection from cold and polluted water, it increases breathing security and provides a space for equipment that lets the diver communicate with the surface support team.
Full face masks can be more secure than breathing from an independent mouthpiece; if the diver becomes unconscious or suffers an oxygen toxicity convulsion, the diver can continue to breathe from the mask unlike a mouthpiece which must be always gripped between the teeth.
Full-face diving masks are often used in professional diving. They are relatively rarely used in recreational diving, where they protect the face from cold water or stings, such as from jellyfish or coral, and prevent the discomfort derived from gripping a mouthpiece between the teeth for long periods.
This type of gear is also sometimes referred to as a Jack Browne rig, named for a Desco engineer who designed an early version of a full-face mask with an integrated air-supply attachment.

Famous quotes containing the words full face, full, face, diving and/or mask:
“Half life is over now,
And I meet full face on dark mornings
The bestial visor, bent in
By the blows of what happened to happen.
What does it prove? Sod all.”
—Philip Larkin (1922–1986)
“1st Murderer. Where’s thy conscience now?...
2nd Murderer. I’ll not meddle with it. It makes a man a coward.... It fills a man full of obstacles. It made me once restore a purse of gold that by chance I found. It beggars any man that keeps it. It is turned out of towns and cities for a dangerous thing, and every man that means to live well endeavors to trust to himself and live without it.”
—William Shakespeare (1564–1616)
“Fate will bring together those a thousand miles apart; without fate, they will miss each other though they come face to face.”
—Chinese proverb.
“all the fine
Points of diving feet together toes pointed hands shaped right
To insert her into water like a needle”
—James Dickey (b. 1923)
“We never really are the adults we pretend to be. We wear the mask and perhaps the clothes and posture of grown-ups, but inside our skin we are never as wise or as sure or as strong as we want to convince ourselves and others we are. We may fool all the rest of the people all of the time, but we never fool our parents. They can see behind the mask of adulthood. To her mommy and daddy, the empress never has on any clothes—and knows it.”
—Frank Pittman (20th century)
