About Mares Abyss 22 Regulator

The Abyss (MR22) diaphragm first stage features the DFC system and a replaceable HP seat connector. The exclusive MARES DFC system featured minimizes the intermediate pressure drop which occurs in all regulators during the inhalation phase. This pressure drop is greater when higher airflow is demanded of the regulator. The DFC system substantially reduces breathing effort and inhalation resistance, especially during deep dives and under high air flow conditions.

The high pressure poppet was designed for a "2 year or 200 dives" service interval; double the high pressure seat life standard! Compact body, in a modern and smart style, it is made of hot-forged nickel-plating and chromed brass. It is fitted with a preferential intermediate pressure port for connection to the primary second stage, plus 3 other LP ports and 2 HP ports with 7/16" UNF thread. The latter are inclined at a 45° angle to allow a more ergonomic layout of hoses.

For extreme demanding conditions, such as use in cold or contaminated water, the Abyss second stage is made of nickel and chrome-plated brass. These materials offer a number of benefits: ruggedness and thinner walls which allow compact dimensions obtained without using smaller-diameter diaphragms; this result in reduced water drag. The second stage ha an anti-freeze function, which is enhanced by the "radiator action" of the metal.

The Abyss 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. Mares Abyss comes with a limited lifetime warranty.

Decent setup but I wish there were a few differences. This reg lack the ability to be adjusted, and the "flex" hose included witht he kit is just a little short and not all that flexible. The hose actually pulls on the reg when in my mouth.

    Comments about Mares Abyss 22 Regulator:

    This is a great regulator. The mouth piece that it came with caused jaw fatigue, but changing it to a custom mold one took 2 mins to do, so I can't consider it a con. It may make a weird "farting" noise when breathing above water, but it's nothing to be concerned about unless it makes the same sound under water, mine doesn't. I've been using it for about 7 months now. Breathing upside down or face up toward surface is not labored at all and overall, imho, it's definitely worth every penny.

      Comments about Mares Abyss 22 Regulator:

      Nothing bad to say about this reg, wish the flex hose was a tad longer, but it really only interferes when on deck of a boat. Under water it's plenty long enough. I like the HP/LP port positions, they don't interfere with anything else on my setup.

      Running this with the Suunto hoseless.

        Comments about Mares Abyss 22 Regulator:

        This is the first reg I bought after getting qualified. Out of the box you could feel the difference in quality from the training regs we were given. The first stage is also quite nice having 2 high pressure ports, makes it very expandable for having back up pressure gauge.

        Bought a miflex hose to go with it, and coudln't be happier.
