Scuba masks
Scuba masks allow one to view the vast underwater panorama available
to the skin diver only. The variety of sights range from fish and sea
mammals to dazzling coral reefs. Masks are made in a variety of styles
and colors. The most important considerations when buying a mask are
comfort, lasting seal, field of vision, comfortable snug-fitting nose
pocket, and the silicone straps and fasteners.
When purchasing scuba masks two of the most common ones found are the
three-pane and four-pane lens. On the three-pane lens the front piece
is a single window with side panel lenses to allow one to see left and
right. A four-pane mask is divided in the front pane and includes the
right and left side pieces. Some divers prefer the three-sided lens
because the frame of the mask doesn’t block their vision while
looking from side to side.
Scuba masks all have different shapes of the nose pockets. This is
where the mask fits underneath the nose to give a water-tight seal.
The pocket cushions and protects one’s nose while keeping the
mask from fogging up during a dive. They also help maintain equalization.
A snug nose pocket will allow the diver to purge his or her mask efficiently.
