AIRTRIM

The BC inflator provides an exceptional new solution for controlling the
inflow and outflow of air.
Its innovative mechanism completely revolutionizes the ergonomics of using
an inflator underwater.
In fact, on traditional BCs the inflator must be secured within easy reach by
a retainer- but this does not always take place, making the inflator difficult
to use.
The innermost end of the group is fitted with a quick coupling which can be
manually detached in the event of a malfunction, to immediately shut off
the flow of air.

EXHAUST VALVES

The BC deflation button actuates an innovative "Twin Exhaust Valve System".
These valves release air simultaneously, regardless of the diver's underwater
swimming position.
This makes it extremely easy to adjust the buoyancy.
This new sophisticated valve system overcomes the limitations of traditional
inflators, which require a specific diver position to facilitate air discharge.



WARNING

The "Twin Exhaust Valve System" allows the user to control the air
discharge rate.
To obtain a quick air dump, press and hold down the "OUT" button.
To obtain gradual deflation, press the "OUT" button lightly and
repeatedly.

All models also feature at least one mechanical quick air dump valve,
operated by a pull cord with a knob, that also functions as an over-expansion
relief valve.

BUOYANCY BAG

First quality fabrics with multilayer polyurethane coating, sealed at high
frequency, in a variety of styles to meet the needs of every diver.

SOFT GRIP

Neutrally buoyant padding specifically designed to provide unparalleled
comfort and ensure maximum adherence between the wetsuit and the BC.

B.P.S. (Back Protection System)

A neutrally buoyant padding system that is both rugged and secure, thanks
to a combination of materials with different mechanical properties. The
capacity to absorb shocks is greatly superior to that of ordinary protection
materials. What's more, the contoured cut and the special design of the
seams ensure exceptional adherence between the wetsuit and BC.

M.R.S. (MECHANICAL RELEASE SYSTEM), PATENTED

The most modern integrated weight release system. Simple, reliable and
easy to use even underwater. The weight compartment, which can hold
any type of weight, is mechanically connected to the BC and always readily
accessible. The oversized release button is easy to use, even when wearing
thick neoprene gloves.

M.R.S. PLUS

M.R.S. Plus represents the evolution of the first mechanical-release weight
system introduced on the market. Incorporating a newly designed buckle
system, simply click the buckle in place for optimum security, one pull
movement to release your weights.

MOUTH INFLATION SYSTEM

The oral inflation system is located inside the pocket, and consists of a small a
silicone tube fitted with a check valve.

MATERIALS

- 1500 denier Cordura®, with triple polyurethane resin coating, extremely
resistant to abrasion.

- 840 D nylon, with triple polyurethane coating, highly resistant to
abrasion.

- High impact YKK® technopolymer zips.

- YKK® Velcro.

- Stainless steel or technopolymer rings.

- Valves, buckles and rings constructed from high impact technopolymer,
resistant to knocks and to aging.

- Shoulder straps with quick-release "thumbledge" buckles, which can
be instantly adjusted using only the thumb, permitting easy, quick and
precise fitting of the BC on different body types. The buckle adjustment
straps are finished with pull-rings which ensure a secure grip, even when
wearing thick neoprene gloves.

- Quick-release waist strap with two-side adjustment.

- Adjustable quick-release chest buckle keeps the shoulder straps in the
correct natural position and prevents them from slipping.

- Double seam construction using 100% polyester thread, for maximum
durability.

- Practical swivel hose retainers ensure safe and optimal positioning of the
octopus and console (Fig. 1).

INSTRUCTIONS FOR USE

Before using the B/C in open water conditions, carefully read the instructions
for use provided in this manual, which can help ensure the life and safety of
the equipment.
It is also recommended to try the B/C in a swimming pool first, donning full gear
as for an open water dive, in order to become acquainted with this equipment
which retains the shape and working principle of the traditional BC, but is used
in a different way.
One recommended shallow water exercise, for example, is to practice
controlling buoyancy while pivoting on the fins. This simple move helps the
diver become familiar with the "IN - OUT" inflation and deflation buttons,
experiencing their air flow rate and - most importantly - their ease of use.
The purpose of a B/C is to make diving easier by enabling the diver to
maintain neutral buoyancy.

INTEGRATED WEIGHTS SYSTEM

M.R.S. PLUS

M.R.S. Plus represents the evolution of the first mechanical-release weight
system introduced on the market. It introduces a newly-designed buckle
system: simply click the buckle in place for optimum security, and a single
outward pull releases your weights. Max load of 6 kg/13 lbs with most sizes.
The interior is divided into multiple sections in the event you do not use the
full capacity.

ASSEMBLING THE INTEGRATED WEIGHT

Open the zipper and insert the desired quantity of weights, up to a maximum
of 6 kg/13 lb in each container (Fig. 2).

FIG. 2

When using a limited quantity of weights, close the Velcro (A) inside the pocket
to prevent the weights from shifting during the dive (Fig. 3).

WARNING

MAKE SURE THAT THE SYSTEM IS CORRECTLY ASSEMBLED BEFORE
STARTING THE DIVE.

POCKETS

The B/C pockets are of the bellows type for increased capacity and can be
easily accessed with the opposite-side arm. Always remember to close the
zip or the Velcro flap to avoid losing any objects contained in the pockets.



WARNING

USE OF BC POCKETS AS WEIGHT HOLDERS TEARING POCKETS:
the pockets are not designed to hold excessive weight. They are
intended exclusively to contain small objects.Inserting weights,
stones, or sharp or pointed objects is considered improper use and
will consequently invalidate the warranty that we offer.

HIGH-VISIBILITY LOGOS

Silver-color bands and logos are attached on the B/C; they are made of a
highly reflective material to provide good visibility even when visibility is low
in typical dim underwater environments.
The reflective logos are located, anteriorly, on the shoulder straps (bands)
and, at the back, on the bladder (MARES logos).

ꔼ

CAUTION

Due to its highly technical properties, the reflecting material
requires a special and difficult attachment procedure. Be careful,
in particular, to avoid scratching your B/C against sand, rocks,
stones etc..
MARES is not liable for partial or total detaching of these logos or
parts thereof.

ADJUSTING THE B/C

CUSTOMIZING THE FIT

Before the B/C is used underwater, it must be adapted to the shape of the
diver's body by making some adjustments.
If the cummerbund needs to be tightened or enlarged, remove it from both
the left and right inner loops and then, using the adjusting strap with buckle,
obtain the desired length by moving the Velcro-covered part backward or
forward (Fig. 8).

Airtrim Line

20

FIG. 8

After completing the adjustment, replace the cummerbund inside its loops
and check the resulting fit, taking into account the thickness of the wetsuit
and ensuring that the two sides are exactly symmetrical.
The cummerbund is correctly adjusted when the Velcro flaps overlap each
other at the center of the diver's waist.
After obtaining the desired girth, use the quick-adjusting shoulder straps on
the left and right side to finish customizing the fit.

PRE-DIVE INSPECTION

1) Check that all fittings and valves are securely fastened and that the
locking nuts are tightened.

2) Make sure that tank and backpack are properly connected (Fig. 9-10).

FIG. 9

FIG. 10

3) Inflate the B/C and wait for approximately 15 minutes If the B/C deflates
at all, do not use it and bring it to a MARES Authorized Service Center for
inspection.

4) Next, check the operation of the pneumatic inflation and deflation
system by pressing the IN and OUT buttons.

Finally, check the oral inflation system using the silicone tube inside the
pocket.
Fully extract the tube and blow into it to inflate the BC.
Replace its cap and correctly reposition the tube inside the pocket.

Volume: Single tank set Max. 20 lt/4.4 gal.
Two-tank set Max. 2 x 10 lt./2.2 gal.



WARNING

Any leakage of micro-bubbles does not indicate that the BC is
losing pressure, but instead could be air that was trapped in spaces
between the fabric fibers.

5) Operate the overpressure / rapid exhaust valve (Fig. 11) to be sure it is

functioning properly.

21

FIG. 11

6) Do not leave the B/C in the sun and do not place or drag it on rough
surfaces that might scrape or puncture it.



WARNING

WHEN USING A BC WITH INTEGRATED WEIGHTS, ALWAYS SECURE
THE UNIT TO A LINE IF YOU ARE PLANNING TO PUT ON THE BC IN
THE WATER. THIS IS BECAUSE, IN CERTAIN CASES, THE SCUBA UNIT
CAN BE NEGATIVELY BUOYANT EVEN WITH THE BC FULLY INFLATED.



WARNING

Always soak the tank fastening straps before securing the B/C to
the air tank. Failure to do so could allow the tank to slip out of the
B/C strap, causing serious injury or death.



WARNING

Remember to fully extract the oral inflation tube before blowing
inside.



WARNING

The rear pockets are sized to accommodate a maximum of 2 kg of
weights each.
Refer to your instructor for information about how to make the
most of this feature.

USING THE B/C UNDERWATER

To begin the descent, there is no need to raise your left arm as with traditional
BCs: simply press the "OUT" button on the inflator unit, or operate one of the
mechanical quick air dump valves by pulling its cord.
During the descent, compensate for the progressive loss of buoyancy by pressing
the "IN" button with your thumb to inflate the BC.

DURING THE ASCENT

To control the speed of ascent, it may be necessary to discharge some of the
excess air.
Use the OUT button, pressing it briefly and repeatedly.
In the event of an excessively rapid ascent, a quick air dump can be obtained
by holding down the OUT button.



WARNING

When ascending, your buoyancy must be controlled to avoid too
rapid an ascent when approaching the surface. For information
concerning a safe rate of ascent, refer to a certified diving
instructor or your diving manual. Follow your decompression table
or diving computer during the whole ascent. Failure to make a
slow, controlled ascent could lead to serious injury or death.



WARNING

Do not use your B/C to lift objects in the water. Should you drop
the object, you could become too buoyant and your rate of ascent
could become too rapid and potentially dangerous and serious
injury or death could result.

ON THE SURFACE

After returning to the surface, inflate the BC to become positively buoyant.



WARNING

A B/C is not a safety jacket or personal floatation device and is not
designed to keep the diver on the surface with head up should
he/she become unconscious.
