Which
mask is the best for you?
Out
of all the masks on the market, how do you find the right one? You
need to narrow it down. First, with some exceptions, the general
rule of thumb for photography, videography, freediving and spearfishing
is that low volume,
black silicone masks are ideal.
Clear silicone has a tendency to cast images or reflection on the
inside of the lens causing distractions or even loss of clarity
to viewing, however, some people prefer clear silicone claiming a
less “claustrophobic” feeling.
Side-windows greatly increase the air volume of a mask making them
restrictive for deeper freediving but can be beneficial to increase
peripheral vision or to at least enable a diver to see movement to
the sides. Nose purges often leak defeating the purpose of the purge
but they can be beneficial if a diver has facial hair or other specific
needs. Proper fit will eliminate the need for a purge. Mirrored lenses
will darken the lens and make seeing into caves more difficult and
darken already poor visibility conditions but they can aid in “hiding” the
divers eyes which can help fish remain calm or even attract them
to the reflection. Color tinted lenses that are tinted too much will
distort your vision, change the color of familiar objects and can
even create nausea in some people but they can also increase depth
perception, clarity and light intake. A mild color tint is recommended.
The air volume of a mask is important for freediving but not as
important for scuba diving. Therefore using a generic “scuba mask” for
freediving is not a good idea but using a low-volume “freediving
mask” for scuba is fine. A low volume mask is an equation of
the distance from your face to the glass x the height and width of
the mask. As a freediver descends, water pressure creates an effect
that pushes the mask against the divers face where a diver must “equalize” the
pressure within the mask or risk causing damage to the divers eyes
and/or sinuses. To equalize the pressure within the mask a diver
needs to exhale from the nose and into the mask. A low volume mask
requires less air that a freediver must “waste” into
the mask. Clearing the pressure in the mask is considered a waste
because the divers lungs cannot utilize the air/oxygen within the
mask, therefore, the more wasted air, the less time a diver can stay
underwater.
The visibility of a mask can vary greatly for each person and each
mask. Visibility is simply defined as how much a person can see
while the mask in on. When fitting
a mask, pay close attention to how far your eyes are from the glass. The distance
from your eyes as well as the height and width of the glass will determine
visibility.
The descriptions of proper fit, air volume and visibility overlap
in some ways so you will need to find a medium between them to
figure out the best overall
fit and comfort.
At this point you have hopefully narrowed down the options and
style of mask you need and want. However, with all the different
options in the market today,
the mask isn’t worth anything if it doesn’t fit you properly. The
shape of your face is the most important feature about mask selection. There
are literally dozens of facial features I look at to determine which selection
of masks will work for each individual. Here are some tips:
The height and weight of a person will help determine the general
face shape. However, a persons ethnic background can also help determine
things like
high cheek bones, flat or substantial cheeks, wide or narrow face, long
and skinny
or flat and wide nose, low or high nose bridge, narrow or greater distance
between eyes, shape of eye socket, flat or protruding brow area, distance
from the bottom
of the nose to the upper lip, fullness of the lips… etc.
If you don’t have access to an experienced mask tender you can use these
tips to help fit a mask on yourself. You will need a mirror for best results.
Step One (1)
Pick up a mask in both hands and hold it up to your
face but before you place it onto your face use your thumbs to gently
fold
back each
side of
the skirt. Gently place the mask on your face but stop as SOON as you
make contact with any part of your face. Release the sides of the skirt
you
were holding with
your thumbs so the skirt will gently touch your face. Do NOT apply
ANY pressure to the mask to push it onto your face. By gently placing
a mask
onto your
face you are trying to see light coming through any gaps between the
skirt and your
face. Keep in mind, if you press ANY mask hard enough it will appear
to fit, when in reality it will not. The best fitting masks will not
show
ANY light
between the skirt and your face and will seem to “stick” to
your face with little or no effort to press it on. Note: Facial hair
or “stubble,” as
well as facial expressions, such as smiling or laughing will GREATLY
decrease the ability to fit a mask properly.
While the mask is placed gently on your face look carefully into
the mirror for any light, all the way around, between the skirt and
your
face. If
you see ANY
light at all the mask may not be right for you. After you have determined
a good fit then proceed to step two (2).
Step Two (2)
Inhale very gently through your nose to verify if
the mask will stick to your face with the minimal effort. Again,
if you
smash
the mask against
your face and suck-in too hard you may make a “bad fitting” mask
appear to fit.
Step Three (3)
Now is the time to press hard, evenly distributing
pressure throughout the mask frame, against the mask to your face.
The purpose
for this is to find
out if the hard frame of the mask hits or makes contact to your
face. This can sometimes be uncomfortable and if it’s uncomfortable
on land it will be very uncomfortable after wearing the mask for
several hours in the water. Common
areas of concern are the bridge of the nose, eye sockets, eyebrow
and cheekbones. If it’s uncomfortable than you may be experiencing
a less than desirable mask. Keep trying different masks until you
find the best medium.
