NEOPRENE TYPE
Made from high density (HD) neoprene material:
Flexible and Durable.
FEATURES:
Typically neoprene material becomes more
durable as its density increases, though the
denser it becomes the less flexible it is. People
enjoying recreational diving want the comfort
that comes with flexibility! Mobby’s has
created an HD neoprene that maximizes
density while achieving supreme flexibility and
utmost durability.
Do not use the dry suit to lift objects heavier than 5.5lbs
underwater. A lift bag should be used to raise heavy objects.

04. MOBBY’S DRY SUITS: TYPES AND CHARACTERISTICS
Since it is made from Foam material, the insulation efficiency
and buoyancy will vary based on the level of water pressure.
FEATURES:
1. Your suit is manufactured with durable fabric
laminated with either a plastic or a breathable
hydrolysis resistant polycarbonate membrane.
2. This material is resistant to water and
chemical agents, and it normally lasts longer
than neoprene dry suits.
3. Because it’s made of durable fabric, you can
use the dry suit in various temperatures by
simply changing the clothing you wear under
the suit.
4. A dry suit made with SHELL fabric has lower
buoyancy and requires less weight than a
neoprene dry suit.
5. A dry suit made with SHELL fabric is lighter,
poses less impediment to movement and
swimming, and can be transported with ease
when you travel.
This suit is intended for use with compressed air or Enriched
Air Nitrox . Do not use any other gas or mixture for inflation of
the suit.
Color-transfer may result from storage in a hot and humid
place. Hang the suit in a cool and dry place preferably on a
hanger conforming to a dry suit.

your suit. The valve can rotate 360 degrees
allowing the low-pressure hose to be connected
in any direction.
・Large inlet lever
You can easily manipulate the valve even with
6.5mm thick gloves on. Rather than simply
pushing a button you can feel the valve in your
hand and operate it. Inflation is manually
triggered with a sliding button system avoiding
sudden and involuntary activation.

SUIT’S ENTRY
Each suit uses an airtight waterproof fastner.
Depending on the model, the fastner can be set
in different places. Even though some of our
models are self-entry, most of them, with a
zipper on the back, require assistance from your
buddy to be properly closed.
NECK & WRIST SEALS
The two main kinds of seals are made from
either latex or neoprene.
Latex Seals: highly waterpoof, they have a
remarkable stretching ability making the suit
easy to don and doff. These must be trimmed
appropriately to fit. (Please refer to page 8 for
cutting instructions).
Neoprene Seals: highly durable and long lasting.
・Large exhaust sliding button
(manually-operated)
You can easily manipulate the valve even with
6.5mm thick gloves on. Rather than simply
pushing a button you can feel the valve in your
hand and operate it. [LOCK]: Inflation is
manually triggered with a sliding button system
avoiding sudden involuntary activation.
Slide the hose connector back to lock the
hose into place over the inlet valve port.
Never connect the suit hose to the high pressure port on the
first stage. The hose would explode and could cause serious
damage.
CONNECTING THE INFLATOR HOSE
To connect the hose, please use the low
pressure port on the side of the valve. Make
sure it is not tangled with any other hoses.
・Outlet pressure adjustment lever

06. INNER WEAR
The heat generated inside the dry suit depends
both on the type of suit and on the type of inner
wear worn. If you wear the right inner wear you
can optimize resistance to heat loss. A good
inner wear is always necessary for diving in
complete comfort and safety.
INNER WEAR SELECTION:
For reference you should choose your inner
wear based on the water temperature, diving
skill level, type of dry suit, diving session time,
physical condition, gender, and if you are
planning a dive in which you will move a great
deal.
Mobby’s offers 3 different options of inner wear
for Shell Dry fabric suits. Please refer to the
catalog and select the items based on your
needs.
If you are planning to buy a ready-made dry suit,
choose the size carefully according to the type
of inner wear you plan to use.
08. DRY SUIT SETTING
The thickness of the undersuit that you wear will influence the
weight on your belt for neutral buoyancy (larger volume of air
gets trapped within). Generally, the thicker the undersuit, the
more weight you’ll need.
Inadequate inner wear may lead to hypothermia or
overheating. Please carefully choose your inner wear based on
the water temperature you will dive.
Overheating is very dangerous when diving with a dry suit. It
can lead to exhaustion, blackout, or even death. Wear the right
It is highly recommended that you correctly set
up and adjust your dry suit for proper fit and
comfort as well as a safe diving session.
Latex Seals adjustment
The latex seals must be trimmed appropriately
to fit. It is a very simple operation, but it requires
a great deal of attention. If you cut away too
much material the error cannot be repaired and
the seals will have to be replaced.
Adjustment method
Turn the suit inside out.
You will find on the seal’s surface molded
lines. Please cut carefully starting from the first
line.

causing serious physical harm.
Make sure to inspect the neck and wrist seals before each
diving session. If you find small cracks on the surface you will
need to replace the seal.
Avoid direct contact of chemicals with the latex seals as they
can breakdown the seal. Examples include hair conditioner,
wax, perfume, etc. If there is contact rinse quickly with fresh
water.
If the neck seal feels too tight, you can insert
a scuba tank and leave it for about two hours to
enlarge it. In the event that you are unable to
perform these tasks, please contact your
authorized MOBBY’S Dealer for assistance.
Similar to the illustration, you can use a scuba
diving tank to enlarge the wrist seals.

Following the molded lines on the seal, remove
one ring of material at a time. Your goal should
be to make each cut on a single pass. The seal
must be adjusted so that if fits properly. When it
is correctly adjusted, the neck seal must be
snug, but not tight.
Please follow the same process for the wrist
seals.
Connecting the Low-pressure hose
The inflator hose supplied with the dry suit must
be connected to the first stage low pressure
port. In the event of a limited number of ports,
you can use a rotating “T” shape adapter. Please
contact your Authorized MOBBY’S dealer for
advice and assistance. Finally, please make sure
that the hose connector is reaching the inlet
valve without being obstructed.
09. HOW TO PUT ON YOUR DRY SUIT
INSPECTING THE DRY SUIT BEFORE DIVING
Always inspect your dry suit before diving by
following the instructions below.
Neck and wrist seals
Seals that are cracked, worn, or sticky must be
replaced.

Inspect it for damage or teeth that are out of
alignment. Damaged zippers must be
replaced. Please contact your Authorized
MOBBY’S Dealer for assistance.
Ask assistance from your buddy to close the
zipper firmly before diving.
Valves
Inspect the inlet and outlet valves for cracks
and damage. Make sure that the valves
function properly and there are no
obstructions.
Furthermore, check that valves are firmly
attached to the suit.
Inner wear
Make sure you prepare and fully set up your
diving equipment before putting on your inner
wear and dry suit, especially on a hot day.
Overheating may result from all of the
operations and movement required to set up
your gear. Furthermore, the sweat will
increase the amount of humidity inside the
suit. It will cool off inside the water resulting in
high volume of condensation.
DRY SUIT DONNING INSTRUCTIONS
Back zipper type:
1. Make sure the suspenders are not twisted.
Insert your feet one at the time into the suit and
pull it up and onto your legs. The knee pads
should be set right on the knees.
4. Insert your right arm and pull the suit up to
your shoulders.
5. Be careful if you have long hair, it might get
caught under the collar. Push your head through
the collar while stretching the latex as much as
possible, holding it between your fingers and
the palms of your hands. For neoprene seals,
you can fold them inside.
7. Once the zipper is closed it will be more
comfortable to wear the dry suit if you take the
time to expel the air inside. Crouch down and
press the discharge valve, holding your arms
crossed over your chest. You can also simply
stretch out the latex collar to let the air out.
4. Push your head through the collar while
stretching the latex as much as possible.
5. Insert your left arm.
2. Slide into the suit and roll it up to your waist.
Make sure the suit fits properly and put on the
suspenders.
3. Insert your left arm into the left sleeve of the
suit. Cup the fingers on your left hand and
carefully insert your fingers into the wrist seal.
Do not force your hand through the seal. Take
your right hand and insert your index and
middle fingers under the wrist seal on your left
hand against your left wrist. Arrange the latex
cuffs so they lie snug against your wrists. They
should fit flat and moved slightly back toward
your elbow. Check that your undersuit is not
trapped inside the cuff, or water will seep into
the suit. There must not be any folds or twisting
in the cuff.
6. You’ll need to ask your dive buddy for help
closing it. Raise your arms in front of you even
with your shoulders and keep them slightly
bent. If you have long hair, tie it back so it
doesn’t get caught in the zipper. Ask your dive
buddy to slide a finger into the slider and to
close the zipper firmly. Make sure that no edges
of the inner wear fabric or hair is caught,
because not only could it cause water seepage
but it could also damage the zipper. The zipper
is not covered by a warranty for accidental
damage or neglect.
Front Zipper type: (S.E.A. Zipper layout)
1. Make sure the suspenders are not twisted.
Insert your feet one at the time into the suit and
pull it up and onto your legs. The knee pads
should be set right on the knees.
6. Slide the zipper down and close it firmly. Be
careful not to catch your inner wear in the
zipper.
2. Slide into the suit and roll it up to your waist.
Put on the suspenders.
3. Insert your right arm.
7.Adjust and fasten the telescopic torso belt.
Do not bend the zipper.
Do not force the zipper if something is stuck inside.
8. Once the zipper is closed it will be more
comfortable to wear the dry suit if you take the
time to expel the air inside the suit. Crouch
down and press the discharge valve, holding
your arms crossed over your chest. You can also
simply stretch out the latex collar to let the air
out.
7. Roll up the zipper close to your abdomen and
then seize the crossed belts on your back to

Whenever you enter the water from a boat or a
beach, make sure your BC is inflated so that you
will be positively buoyant on the surface.
8. Once the zipper is closed it will be more
comfortable to wear the dry suit if you take the
time to expel the air inside the suit. Crouch
down and press the discharge valve, holding
your arms crossed over your chest. You can also
simply stretch out the latex collar to let the air
out.
In the event of waves, do not over inflate your
BC so that you are able to dive below the waves.
It is likely that at the end of the dive, when your tanks are
nearly empty, you will need additional weights in order to
complete your safety stop. Make sure your BC is correctly
inflated when you are at the water surface.
Compression of the suit during the dive
As soon as you enter the water you will notice
slight compression of the suit to your body. This
is due to the pressure that water exerts on
immersed bodies. To compensate, simply inflate
a minimal amount of air into your suit.
Always wear a BC during your dives. Do not jump into the
water from higher than one meter because it could damage
4. Pull the suit up on your shoulders.
Donning the Scuba unit
Ask your buddy to help you put on the unit. You
may damage the suit trying to put it on without
assistance.
Always wear a BC during your dives. This device is essential
for surface flotation and for ascending.
6. Close the front zipper firmly. Be careful not to
catch your inner wear in the zipper.
Diving without air inflated into your suit may cause an
dry suit diving. You must practice in a safe environment,
Entry
Before entering the water you need to
completely expel all the air inside the suit.
2. Pull the dry suit and roll it up up to your waist.
Put on the suspenders.
5. Push your head through the collar while
stretching the latex seal. Be careful not to catch
your hair or inner wear in the zipper.
This manual cannot replace training in a course specifically for
authorized to teach a dry suit diving course.
1. Check that the neck fastener is fully open.
Slide into the suit one leg at a time.
3. Insert your arms one at a time. Cup your
fingers and carefully insert your hand into the
wrist seal. Be careful not to damage the seal
with your nails. Arrange the latex cuffs so they
lie snug against your wrists. They should fit flat.
Check that your innerwear is not trapped inside
the cuff. There must not be any folds or twisting.
10. DIVING WITH YOUR DRY SUIT

Make sure that your suit doesn’t restrain your
mobility and allows you to use your diving
instrument and gear with ease.
your suit.
Always dive with the least weight possible. Always keep a
minimum quantity of air in your suit. Blowing too much air
Check your buoyancy before diving
It is recommended to check your buoyancy
under the supervision of an instructor qualified
to teach dry suit diving. Check your buoyancy in
order to determine the proper weight in shallow
water.
Proper weight depends on your body type, your
type of Mobby’s dry suit, the undersuit you are
wearing, and the type of tank.
After you have put on the unit, enter the water
at a point where you can touch the bottom or
hold onto a ladder. In any case, never dive into
the water.
While swimming on the surface, expel all air
from your BC. If you begin to descend as soon as
you deflate the BC just a tiny bit, it means that
you are too negatively buoyant, and that you
must remove a few kilos from your belt before
proceeding.
into the suit could make it difficult to control your buoyancy
and could lead to an unexpected rapid ascent.
How to begin the dive
Before beginning the dive, make sure that the
exhaust valve is set on [AUTO].
Empty your BC.
Lift your left elbow to allow the air to channel
upward and exit through the valve. Your wrist
should be lower than your elbow.
You may not be able to see the valve, but you
will certainly be able to feel the air exiting.
Do not suddenly exhaust a large amount of air from your suit.
You will lose neutral buoyancy and it may lead to a rapid and
uncontrolled descent. Make sure you do not release too much
air at one time.
Inflate with air in stages, pressing the button a few times
quickly instead of in one long blast. This is especially
important when ice diving, because it will prevent the exhaust
valve from becoming blocked. It will also prevent you from
sending too much air.
Do not use the dry suit to lift objects heavier than 5.5 lbs
underwater. A lift bag should be used to raise heavy objects.
If you were to use the buoyancy of your dry suit or BC vest for
such a recovery operation and then lose your grip on the
Empty your lungs. And when you start to
descent, lower your arm.
(Make sure the valve is set on [LOCK])
Neutral buoyancy at depth
Do not add air to both the suit and the BC at
depth, because it will be more difficult to
control both volumes of air at the same time.
Primarily add air to the dry suit. At depth, you
will need a sufficient amount of air in your suit
to allow you to maintain neutral buoyancy.
Use the inflation valve to regulate your
buoyancy at depth. Add a minimal amount of air
to compensate for the suit’s compression due to
the water pressure. If you add too much air you
will not be able to continue your descent.
To move air into your boot, you will need to
move to a horizontal position, parallel to the
surface of the water.
In the event of an excess of air, lift your left
elbow to allow the air to channel upward and
exit through the valve. Your wrist should be
lower than your elbow.
object, you would find yourself making a rapid and
uncontrolled ascent.
How to ascend
Before beginning your ascent, make sure that
the exhaust valve is set on [AUTO]. As soon as
you start to ascend, the air inside your dry suit
will begin to expand. That means that you must
begin to exhaust air from the valve on your arm
at the same time. Don’t forget to keep a position
with your left arm at the highest position. If you
begin to ascend too quickly, you can intervene
manually by pressing the valve button.
If you have trouble beginning your ascent, you
will have to add a little air to your suit.
Make sure that you control your ascent by
monitoring information about your dive using
your instruments (depth gauge, dive watch and
computer).
To slow down your ascent you can also spread
out your arms and legs and use your fins for
further control of your ascent.
If you are accustomed to diving with a lot of
weight on your belt, you will have to close the
exhaust valve to allow the dry suit to retain
enough air to achieve neutral buoyancy at
depth. However, this practice is not advised in
recreational diving and should be avoided.
Position during diving
You are advised to maintain a horizontal
position during the dive. Your head and feet
should be level, unless you are involved in
special activities such as wreck diving, cave
diving, or ice diving. In addition, in this position
the suit will adhere less to your body, since it
will be less affected by the effect of water
pressure.
An excess of weight may cause pain on the back and hips. To
If you find yourself head down, it will be impossible to
exhaust air. Make sure you are parallel to the sea surface or in
a head up position to allow air to exhaust.
As soon as you reach the surface, you should
inflate your BC so that you can swim back to
your exit point. Use your BC to achieve positive
buoyancy on the surface. Never use your dry
suit to float on the surface. It is advisable to
completely close the dry suit exhaust valve to
prevent any water seepage as you swim.
Remember to open it again before beginning
your next dive.
provide a better balance and avoid additional discomfort you
can use extra weight accessories such as ankle weights.
However please be cautious that it won’t bother you during a
diving session requiring intensive fin kick.
Never use your dry suit to float on the surface. Especially in
the case of a neoprene neck seal. The high air pressure will
compress the throat causing breathing difficulties and may
also restrict the normal flow of blood to the brain, which
could cause serious harm to your physical safety.
Do not suddenly inflate your suit with a large amount of air. It
may cause a rapid and uncontrolled ascent.
Possible reasons for an outlet valve malfunction
If the valve leaks:
If the exhaust valve leaks, your suit will not be
airtight and you will also get wet quickly.
Immediately stop your dive, and use your BC to
control your buoyancy and return to the surface.
11. EMERGENCY PROCEDURES
Mobby’s dry suits are manufactured to the
strictest quality controls and conforming to the
highest safety standards. In any event you
should be ready for any emergency procedure.
The valve is stuck in the closed position:
If the exhaust valve gets stuck in the closed
position, the only thing you can do is let air out of
the latex seals at your neck and wrists. However,
this maneuver will allow a certain amount of
water to seep into your suit.
Emergency procedures related to diving with a dry suit must
be practiced in a contained area such as a pool and under the
supervision of an instructor authorized to teach a dry suit
before diving in open water.
If you have more air in your suit, returning to a
vertical position could be more difficult, unless
you have sufficiently practiced the emergency
procedures.
If you find yourself near the bottom:
Kick vigorously toward the bottom.
Grabbing hold of a rock, rotate yourself to a
vertical position.
Immediately release air from your suit until you
regain your neutral buoyancy.
If you find yourself head down at mid-depth:
Kick vigorously toward the bottom.
Continue kicking, and stretch your chest
forward or arch your back. Roll forward or
backward to return to an upright position.
Immediately release air from the valve until you
recover neutral buoyancy.
Use your BC to regain neutral buoyancy.
Move the area that is leaking as far downward
as possible to reduce both the loss of air from
the suit and infiltration of water.
Begin a controlled ascent.
Modest water seepage does not constitute
true flooding.
course. You should be comfortable with these procedures
How to recover your buoyancy from an upside
down position. (Dry suits without foot valves):
If you ever rotate into a head-down position,
the air in your suit will move immediately to the
area of your boots. As long as you remain in the
head-down position, it is impossible to release
air from your suit. Therefore, you will have to
regain a proper position.
WHAT TO DO IF YOUR SUIT FLOODS
Dry suits hardly ever flood, but if the zipper
were to break or if the material were to tear in
an accident, then the suit could begin to rapidly
fill with water. In this case, you must abandon
your dive and follow these steps.
Foot valves will exhaust the air in the boots in a
head-down position. Thus, allowing you to
regain head-up position with greater ease.
CONDENSATION
Even if there is no water seepage, some
condensation may occur inside the suit. This is
very commom and usually happens for several
reasons.
Possible reasons for an inlet valve malfunction
The valve is stuck in the open position:
If you do not appropriately observe maintenance
procedures for your dry suit, the inflation valve
may get stuck in the open position rapidly
inflating air into your suit. The inflation valve may
freeze and get stuck during ice diving as well.
Immediately disconnect the inflation hose from
the valve and release the excess of air through
the exhaust valve. The following instructions
have to be perform quickly, otherwise it could
lead to an uncontrolled ascent which could
seriously harm your safey.
Raise your left elbow as high as possible and
activate the exhaust valve manually. Air will
release rapidly. Once fully open, the exhaust
valves are designed specifically to release air
faster than the inflation valves.
The valve does not supply air:
If during your descent you notice that you are
unable to add air to your suit even though the
hose is connected correctly, immediately
interrupt your dive and return to the surface. If
you are negatively buoyant, use your BC to help
you ascend.
For example, on the surface, if there is a large
difference in temperature between the
external air and the water in which you are
diving, small drops of condensation will likely
be created inside as the dry suit cools when you
begin your dive.
In the event you are not able to expel the air,
get into a spread eagle emergency ascent
position.
[Spread Eagle] is an emergency ascent
position with your arms and legs spread and
your back arched to provide the greatest
possible resistance to the water. DO NOT
HOLD YOUR BREATH! Remember to keep
exhaling while you ascend.
Stretching out in the “spread-eagle” horizontal position is a
procedure you should only use in an emergency uncontrolled
ascent. Do not try to execute this procedure unless you are
being supervised by an instructor qualified to teach a dry suit
course.
WHAT TO DO IF YOU LOSE YOUR WEIGHT BELT
If you lose your weight belt during the dive, you
will suddenly become positively buoyant.
If you feel the belt releasing, always try to catch
it. If you can’t, immediately grab hold of
something stationary, such as a rock or the
anchor line, and immediately release air from
your suit. If there is nothing within reach,
stretch into the emergency ascent position,
with your arms and legs spread and your back
arched. Remember to keep exhaling while you
ascend. If the valve does not release enough air,
gently open the latex coller or cuff while you
ascend in the emergency position.
12. DOFFING YOUR DRY SUIT
If the temperature outside is moderate, you
should open the zipper of your dry suit to avoid
overheating. You can also remove the upper
portion of the suit, or you can even remove the
suit entirely.
BACK ZIPPER
1. Ask assistance from your buddy to open the
zipper. Raise your arms in front of you even with
your shoulders and keep them slightly bent.
Make sure that no edges of the undersuit fabric
or hair are entrapped.
2. Grab and pull the lapel above your jaw, and
then push your head through the collar while
stretching the neck seal as much as possible,
holding it between your fingers and the palms
of your hands. Make sure that no hair is
trapped.
13. CARE AND MAINTENANCE
FRONT ZIPPER (S.E.A. ZIPPER LAYOUT)
1. Open the Velcro closures of the dry suit (if
applicable).
2. Fully open the front zipper. Slide your left
hand under the seal, and enlarge it while
retracting your right hand into the sleeve. Take
care to avoid damaging the seal with your
fingernails.

6. Pull off the boots, removing them from the
heel. Sit down and remove the rest of the suit.
WRAP LAYOUT SYSTEM
1. Open the side buckles.
AFTER CARE
Your suit will last a long time and will retain all of
its functions at maximum performance levels if
properly maintained. After each dive it must be
carefully rinsed with fresh water, especially the
zipper and valves. If any amount of water has
seeped into the suit, you must also rinse the
inside. We suggest that you also rinse inside if it
is damp simply due to your own perspiration.
Use only fresh water to rinse your dry suit. Do not use boiling
water or any chemial agent. You may damage the suit
material or cause colors to fade.
After rinsing carefully, hang it up to dry. Turn it
inside out to make sure you dry it completely.
Be careful not to lay the suit in the direct sun
light.
Waterproof Zipper
Use a soft-bristled toothbrush soaked in water
and neutral soap to carefully wash all areas of
the zipper. Once it has dried, lubricate the outer
section only with some recommended paraffin
or wax.

SEALS
The neck and wrist seals must be rinsed with
fresh water and neutral soap. Makeup and body
oils will noticeably damage the latex, shortening
its working life and compromising performance.
Once fully dry, sprinkle them with talcum
powder.
Do not force the waterproof zipper. If you use too much force
you may damage or bend the zipper teeth element.

neoprene leading to water leakage. Similar results can occur
if heavy objects are laid on the suits for a prolonged length of
time.
14. REPAIR
Please contact your Authorized MOBBY’S Dealer
for advice and assistance.
(1) Water seepage may occur due to various
reasons. Before you get ready to repair your dry
suit, please check the following points:
・Did you fully close the dry zipper?
・Was the fabric of your undersuit partially
trapped under your latex cuffs or collar?
・Were the exhaust valves partially jammed by
residue of dirt, hair, mud, etc.?
・Could the humidity inside the suit be caused
by excessive perspiration?
・Did you make any excessive movements that
may have caused some water to enter the suit?
(2) MICRO HOLE REPAIR
If you decide to repair a micro hole yourself,
please follow the steps listed below:
Seal off the latex seals with rubber elastic bands,
close the exhaust valve, and inflate the suit with
air until it is fully inflated.
Brush the suspected area of the suit with a soapy
solution. Make a mark for your reference.
Once you have located the micro-hole, carefully
remove the soapy solution, dry the suit and
release the air.
Cut two appropriate sized patches from the
repair fabric provided with your dry suit. Attach
the patches as indicated in the instructions,
placing a patch on each side of the hole.
If you add excessive amounts of air you could damage the dry
zipper or the suit bonding structure. Only inflate with the
proper amount of air.
15. WRIST AND ANKLE VALVES (OPTIONS)
(3) Latex seal, waterpoof zipper replacement:
We highly recommend that you contact your
Authorized MOBBY’S Dealer to perform these
operations.
On a dry suit you have the option to add extra
valves on the wrists and ankles.
*Depending on the suit structure it might not be
possible.
(4) Periodic inspection:
Make sure your periodic overhaul inspection is
done by your Authorized MOBBY’S Dealer.
The inspection should be performed every 100
tanks, or within a year of your last inspection
regardless of the number of dives.
Small and compact, the wrist and ankle valves
are used to support the main exhaust valve by
exhausting air automatically. The exhaust
pressure level is already pre-set.
User maintenance for wrist and foot valves
Turn the cover counterclockwise while
pushing down the strip button. Remove
the cover.
Set up on each ankle, the valves will allow you to
exhaust excess air that moves from the upper
body to your legs.
・Allows you to adopt any posture while diving.
・Allows to exhaust the air at the water surface
level or in a head first position.
・Prevents uncontrolled rapid ascent.
・Prevents excess air from accumulating in your
boots.
In addition, the wrist valve will allow you to
exhaust excess air in a difficult position simply
by raising your arm.
Remove the spring and retainer.
The wrist and ankle valves are used solely for extra support
and are not to be used for primary exhaust valves.
Remove the valve sheet from the retina.
Make sure the cover has been correctly locked. It may come
off which would lead to a water leak. Lay the parts out to dry
in a well-ventilated place. Be careful not to lay the valve in
direct sunlight. Do not use any type of lubricant spray and/or
grease on the small parts.
Rinse the dissembled parts with lukewarm
water to remove the salt, sand, or dirt.
(2) STORAGE
Make sure that both the wrist and foot valves are
attached before you store your dry suit. Do not
store in direct sunlight. The suit must be placed
in a well-ventilated and cool place with low
humidity.
Improper use of the wrist and foot valves can cause serious
injury. You must be familiar with how the valves work prior to
use. It is recommended that you practice first in shallow
water.
