About Mares Carbon 52 Regulator

The Carbon 52 Regulator is available with the Compact Top Performer MR52 First Stage: the best for a unique high caliber set up. The Carbon 52 incorporates a Double DFC System that provides a Consistent Flow of air at any Depth, even when breathing simultaneously from both the Primary Second Stage and the Octopus. The Natural Convection Channel (NCC) System and the design of the Carbon 52 Second Stage with complete Carbon Material Design, allows this combination to achieve very High Performance in Cold Water. The NCC System increases cold water performance by creating a flow of water across the regulator. The flow is driven by the change of density in water with temperature. The Carbon 52's Pre-Oriented Pressure Ports provide for an ideal placement of hoses even when using two independent regulators.

The all Chrome Plated Marine Brass First Stage Regulator is a Balanced Diaphragm Design which transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism.

The Carbon 52 uses Tri-Material Valve Technology. This patented technology created to optimiz e performance, safety and reliability. The valve is covered with a hard Polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty" PU) reaches new levels of durability.

Another unique feature of the first-stage is the Dynamic Flow Control (DFC). The DFC system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler more reliable second stage. No type of manual adjustment of the second stage is necessary due to the consistency derived from a first stage that guarantees a stable flow of air, even under extreme conditions. The First Stage is equipped with 3 LP ports with 3/8" and 1 LP port with 1/2" Threads. There are also 2 7/8" HP ports for attachment of a Pressure Gauge or Air Integrated Console.

For extreme demanding conditions, such as use in cold water, the Carbon 52 Second Stage Case is made of 100% Carbon. The Superior Thermal Conductivity of Carbon Reduces the Condensation of Humidity in the Exhaled Breath thereby Diminishing the Dry Mouth feeling at the end of the dive. This material offers Extreme Light Weight and Exceptional Mechanical Resistance.

The Carbon 52 Second Stage with its Vortex Assist Design (V.A.D.) system: all Mares second stages offer the unique patented VAD system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in the center this keeps the diaphragm down during inhalation, giving very sensitive and easy breathing at all depths. The second stage cover features the new "mesh-grid" system for water inflow and outflow, which provides a further performance improvement.

Furthermore, the compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. The mouthpiece is made of soft hypoallergenic silicone: limiting jaw fatigue and offering a secure fit even after very long dives. Mares developed the Superflex hose after many years of testing and research. The results achieved far surpassed the tests required by EN250. Hose is extremely light weight and exceptionally soft, guaranteeing the maximum freedom of movement and further reducing jaw fatigue. Superflex hose is 1/2" Threaded High Flow hose and is 29.5" (75 cm) in length. The regulators total weight is 2.28 lbs (1.034 kg) Mares Abyss 52 comes with a Comprehensive Owner's Manual and a limited lifetime warranty.

Questions about this item:

pearl v  Can be used for tech diving too? Is it compatible with all kinds of BCD's?
WAYNE H  hi im not a tech diver but my buddy is he loves his
Shopper  Could it be used for Nitrox diving??
MICHAEL T  Yes, no problem
Steven H  I have a wrist mounted, transmitter connected dive computer and I was wondering if the angle of connection for the HP ports would interfere with installation? As in, if I have my transmitter installed on this reg will I be able to install the reg without the transmitter striking the bottle? I looked at the Navy and it seems a steeper angle and would def interfere but this looks like less of an angle. Does anyone out there have this reg and can attest to whether or not I would be able to use it?
Monica s  The HP ports are angled upward so its not a problem for a transmitter
