REFERENCES TO EN 250: 2000 OBJECT - DEFINITIONS - LIMITS
Object: The requirements and tests provided for in EN 250: 2000 are aimed
at providing a minimum safety level for the operating of diving breathing apparatuses at a maximum depth of 50 m/ 162 feet.
Scuba - Definition (EN 132): Self-contained, open-circuit compressed
air underwater breathing apparatus in an apparatus which has a portable supply of compressed air carried by the diver, allowing him to breathe underwater.
Scuba - Minimum equipment (EN 250: 2000):
a) Air cylinder / cylinders. b) Demand regulator. c) Safety device, e.g. pressure gauge / computer or reserve or alarm. d) Carrying frame or holding device for air cylinder(s) to mount
the harness, or carrying system, e.g. backpack and/or straps, B/C
harness. e) Facepiece: mouthpiece assembly or full face mask or diving helmet. f) Operating instructions.
Limits (EN 250: 2000) - Maximum depth: 50 m / 162 feet.
SCUBA - Component units (EN 250: 2000): The SCUBA equipment
may consist of separate component units such as cylinders, regulator and pressure gauge. The MARES B/Cs described in this manual may be used with any SCUBA components certified in compliance with EC directive 89/686. The air contained in the cylinders must comply with the requirements for breathable air set forth in EN 12021.
REFERENCES TO EN 1809 OBJECTS - DEFINITIONS - LIMITS
Object: The EN 1809 directive examines the minimum safety requirements
and the performance of inflatable buoyancy compensator vests.
Buoyancy Compensator Vest - Definition (EN 1809): A device allowing
the diver to control his/her buoyancy during the dive.
Limits: The object of the EN 1809 Standard does not cover the requirements
for floating devices or safety jackets. A buoyancy compensator vest is not intended to guarantee, on the surface, a head-up position to an unconscious or a temporarily disabled diver.
WARNING
Read this manual carefully. The improper use of any diving equipment can result in serious injury or death. SCUBA diving equipment should be used by certified divers only. Professional training should be obtained exclusively from a certified instructor. For your protection, your equipment should be serviced by MARES or a MARES AUTHORIZED SERVICE CENTER.
The BCs described in this manual have been tested and certified for temperatures between -20°C and + 60°C. The following warning label is stitched on the BC.
IMPORTANT
Read the instructions carefully. The BC is not a life vest: it does not guarantee a head-up position of the diver on the surface. If the instruction manual is lost, it can be re-ordered from your MARES dealer. Before use, check for any air leaks and make sure all the components of the BC are working correctly. Connect the LP hoses to a Low Pressure port of the 1st stage BEFORE connecting the regulator to the tank. After use, rinse the inside and outside of the BC thoroughly with fresh water. This operation is particularly important after use in a swimming pool. Inadequate maintenance may result in damage to the BC or impair its operation. Inflate the BC slightly before storing. Do not remove this label for any reason.

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.

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).
