Not all masks are created equal! There are marked differences
when it comes to the quality of mask construction and materials.
There are two types of materials used to construct most mask
skirts on the market today. The first is plastic and the second
is silicone. Plastic mask skirts are generally very inexpensive,
and are fine for kids' use in swimming pools, etc. Plastic
mask skirts (or vinyl, or PVC) will not last as long as a
silicone mask will, due to the nature of the plastic material.
Plastic will crack after repeated use in the sun or in chlorinated
water (swimming pools).
Silicone masks, on the other hand, will last the user upwards
of ten years, if cared for properly. Silicone mask skirts
will always fit better, and give a better seal than other
materials. This is because silicone has more elasticity, and
can withstand repeated use in any type of water conditions.
Silicone mask skirts come in two colors, clear and black,
with the choice being a matter of personal preference. Clear
skirts will allow more light to enter the mask, and give a
brighter view of the environment. Black skirted masks, however,
are very popular with photographers who prefer not to have
any extraneous light entering their camera's viewfinder.
How should a mask fit? This is a question that has lots of
answers. First, try the mask on without the strap. Place the
mask on your face and inhale through your nose very lightly.
You should feel an even seal around the perimeter of the mask,
with no air leaking through the mask at any point. Be especially
cautious of the areas next to your eyes and under your nose,
where lots of folks have some little lines or creases that
can prevent a mask from sealing properly. Once you're satisfied
the mask fit without the strap, go ahead and place the mask
on with the strap. Is there any discomfort......do you feel
any air leaking when you try to inhale?
Let's talk about styles now. There a lots of different styles
on the market today....single lens designs, twin lens, three
lens and even four lens designs. As you move up in the number
of lenses, the internal volume of the mask (the amount of
air space inside the mask) tends to increase. This has both
advantages and disadvantages. The advantage is that you will
get better peripheral vision from a multi-window mask. The
downside is that if the mask leaks somewhat it requires more
effort to clear the water out of the mask. A great feature
for snorkelers is a purge valve mask. This type of mask has
a small one-way valve that will allow the wearer to purge
or remove the water from the mask without lifting the face
from the water. All that is required is to hold the entire
mask firmly against your face, and blow through your nose,
keeping the purge valve at the lowest point of ther mask.
This design saves energy and allows the wearer to keep their
face in the water.
In it's most basic form, a snorkel is nothing more than a
tube that allows you to breathe with your face underwater.
The things to look for in a snorkel are a large diameter tube,
allowing air to pass freely through the snorkel, and some
type of purge valve system, which lets you use the force of
gravity to help you move water down through the snorkel, rather
than up against the force of gravity. The purge valve on better
snorkels operates the same way as those on masks.....keep
the snorkel bottom in the water, and blow forcefully to move
the water through the purge valve, take a cautious breath,
and you're back to snorkeling! Snorkels cannot be more than
about 17 inches long, because your lungs do not have the strength
to fully move against the water pressure. Some snorkels are
curved to fit the side of your head better, making the snorkel
less resistant to water, causing less drag. Other models have
"dry tops" on them, meaning they have special one-way valves
that will close off the top of the snorkel when the user dips
their head under water or if a wave comes over the top of
the user's head. These valves work great for those that have
had a less than desirable previous experience, or for those
that can't purge their snorkel completely of water when it
fills. The best snorkels have special mouthpieces designed
by an orthodontist, to alleviate the jaw and mouth discomfort
some folks have when snorkeling for extended periods.
Like masks and snorkels there are lots of different fins on
the market today. Some fins are better utilized for Scuba
Diving, rather than snorkeling. There are really two types
of fins used, and these are full-foot or adjustable heel models.
Again, each has it's own advantages. For example, the full-foot
fins, which are designed to be worn barefoot, are better for
travel, as they weigh less, and are generally shorter and
narrower than the adjustable heel style. The full-foot fins
come in a variety of price ranges and materials, with thermoplastic
blades and rubber foot pockets being most common for snorkeling
fins. Adjustable heel fins require the use of neoprene booties
to protect your feet from the rather stiff foot pocket. The
booties will, however, make rocky or coral shoreline entries
much more comfortable, as well as warmer in cooler local waters.
The downside to strap fins is their bulk...they tend to be
heavier and more cumbersome for snorkeling than full-foot
styles, consequently you'll see more Wisconsin divers using
this type of fin for local diving. They also provide more
proulsion with scuba gear than full-foot styles can. Strap
style fins may be used in both warm and cooler waters, with
many folks simply changing the thickness of booties they wear
when traveling to warmer waters. When selecting fins, most
manufacturers make their full-foot fins in regular men's shoe
sizes. Women generally have to order one size smaller than
a man's size for best fit. Full-foot fins should be worn comfortably,
but not tight, as this can cause irritation on the top of
the foot and can also cause blisters in the toe area. Adjustable
heel fins generally come in three sizes...small, regular,
and extra large. The small sizes generally fit shoe sizes
7 through 8, while the regular sizes fit sizes 9 thru 10,
and the extra large size fits 11 and up. Some things to consider
when trying adjustable heel fins: make sure you try them with
booties. Next, be sure there are no tight areas; the fins
should be comfortable across all parts of your foot. Extend
your foot outwards to see if there are any tight spots across
the top of your foot. Next, try wiggling your toes, so you'll
have good circulation. Lastly, try wiggling the entire fin
side-to-side, to see how much play there is in the toe area.
A little is OK, but too much will cause leg cramps. Either
style of fins should feel like they're an extension of your
leg.
Some of the most popular accessories for scuba and snorkeling
include lights, slates, and marine life identification cards
or books. Lights are a great way to explore the marine world
at night or early in the morning. Some of the most colorful
and interesting life can be found once the sun goes down.
Lights also help bring out the natural colors in corals and
fish, because as the light passes through water, some colors
like red get absorbed, and a light will bring out the true
colors. Having a waterproof writing slate with you can be
helpful when trying to describe a fish you saw, or when recording
data about your adventure. Even the most experienced snorkeler
sometimes has a difficult time remembering all the names of
fish they see, so having fish ID cards with you or a set of
fish ID books at home will make the job of identifyng fish
and corals much easier.
Because today's equipment is made from better materials, the
need for special care is practically eliminated. There is
really no other requirement other than to rinse all your gear
well in fresh water as soon as possible to avoid odors or
bacteria forming in your gear. There are special cleaners
available for deeper cleaning; these cleaners contain enzymes
that will attack the odor causing bacteria and eliminate them,
while giving your gear a fresh scent. Mask skirts sometimes
can have a buildup of suntan lotion on them....this is easily
removed by mild detergent and warm water. Some folks use dish
soap as a general purpose cleaner, as it cuts through grease
and rinses away easily. Before each outing or trip, inspect
all your gear for any tears, cuts, or breaks. Most locations
will have spare mask straps and snorkel keepers, but why bother?
Keep one of each in with your gear and you'll never have to
postpone or cancel an outing because you can't get a replacement
part.
