Best over all regulator on the market

By SEAN H.

 -  Anchorage, AK, US

I've used a few regulators and those one has been the best. Easy to tune, never freezes up and we do a ton of cold water diving! Breathes so good!

 

84 dives and counting

By Sebastien B.

 -  Montreal, QC, CA

I have over 80 dives with regulator and works really well in both cold (fresh) and warm waters. It breathes nicely and is super robust. It does sit a little high on the cylinder and takes some time figuring out the good height of your BCD before you stop banging your head on it but other then that, i cannot find a flaw to this thing. I stongly recommend it.

The Abyss 22 Navy II is the Mares answer for your challenge in every condition. With careful analysis and evaluation of what happens in cold water, Mares has designed an exclusive product accurately studied to guarantee top performance and reliability under the toughest conditions, including diving under the ice.

The all chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The Navy 22 Abyss II takes it one step further with the CWD. These kits further eliminate cold water from entering the spring cavity keeping the water further away from the internal mechanism and not allow the air flow of the regulator to be affected by the cold water.

The Abyss 22 Navy II uses Tri-Material Valve Technology. This patented technology created to optimize 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.

All metal technology second stages have superior performance over plastic second stages, especially in cold water, due to the high thermal conductivity that limits the freezing effect. Additional benefits are the improved durability, the longer working life and less dry mouth from breathing compressed air. This all metal second stage is made of marine grade brass and then coated with a special fluoropolymer resin finish on the second stage case and all key components to prevent ice crystals from forming in extreme cold conditions.

The patented mesh design of the second stage cover reduces the pressure of water flowing onto the regulators diaphragm and minimizes free-flow. Even in a strong current it eliminates the need for a knob to de-tune your air delivery system- advance technology through basic physics.

All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths. In a strenuous, unmanned evaluation performed by the U.S. Navy Experimental Diving Unit (NEDU) the Abyss 22 Navy II surpassed the high qualifications and standards of the US Navy cold regulator testing at 190' FSW (58 meters) for General Service and in water temperatures below 38°F (3.3°). Upon the Abyss 22 Navy II's approval by the NEDU, it has now been included in the AMU list (Authorized for Military Use) Approval Number 1.3.16. The regulator 47.2 oz. (1337 g), comes with a 1/2" threaded 29.5" (75 cm) low pressure hose, has 1/2" UNF threaded low pressure port, three 3/8" UNF threaded low pressure ports, and two 7/16" UNF high pressure ports.

This product can only be shipped to U.S. addresses.

Stage 2

Great first stage no problems in cold water. Unfortunatly, I do not like the Vortex system. It feed you too much air and in order to stop it you have to push pressure back into mouth piece, this causes jaw fatigue. I don't recommend for others by I blocked the Vortex with metal puddy, now it works fine.

Best first and second stage on the market

By Karl Z.

from Manila, Metro Manila, PH

This is currently the best first & second stage that you could possibly own. Performs flawlessly as expected in any diving situation. Breathing is simply rock solid. I have full confidence with this unit no matter the purpose the of dive. Indeed,Authorized for Military Use (AMU) as indicated. Forget about fancy overpriced & overrated rigs.

 

Rock Solid Regulator

By Mark W.

Best of the best. Very durable military approved first and second stage. Breathtaking rock solid performance at any depth. Never had any issues with it at all.

 

Great in ice and warmer conditions

By IceBoy

I've used this regulator for around 30 dives, with the last ten being freshwater ice dives. In warm water it has been a fine regulator, likely no different from a standard Mares 22. The second stage does tend to freeflow at the surface if the mouthpiece faces up. I've read that this may be a sign of a perfectly tuned regulator. Under ice, it behaved just as well. At the end of my course, we made a deliberate effort to try and freeze it. A minute of rapid breathing had no effect. It took over 30 seconds of continuous purging before the second stage locked. My instructor was very impressed, based on his experience with loads of other ice ready regulators. With that residence, I doubt it will ever freeze in normal use under ice.

 

Easy Breather

By sgravesmedical

from Toronto, ON, CA

only downside is that it's a bit heavy and once on your tank sits a bit high making it easy to bang your head on it. Once you have mastered the height at which your tank needs to be then you are golden..great reg..

 

Very Well Made

By Cold B.

I wanted a highly reliable first & second stage for my Deco bottle when tech diving. The Mares Abyss Navy gives me that comfort, knowing that it is reliable at 165 ft, in +3 C water. I'm happy with this product and will recommend it!

Questions & Answers

Questions about this item:

Rich H  does this not come with an environmental cap?
Christopher D  It comes with the Mares Cold Water Diving Kit, which is an environmental seal
박종인 박  how many number LP port?
Glenn G  The regulator has 4 low pressure ports and 2 high pressure ports
SEAN H  Pretty standard first stage. 4 LP ports and 2 HP ports. I do a ton of dry suit diving so I have my suit, my red and back up reg all hooked up as well as my bcd. All low pressure. Then monolog gauges as well as computer consider so. I have all 6 PORTS used.
DOUGLAS F  1 LP 1/2” UNF port, 3 LP 3/8” UNF ports
Shopper  I just purchased the Mares Abyss 22 Navy II. The picture on the site shows it with the Name NAVY printed on it. Mine came with the letters AMU printed on it. What does AMU stand for???
WILL D  "Authorized for Military Use," meaning it's been tested & approved by the US Navy.
SEAN H  He "AMU" stands for "Authorized For Military Use" It went through rigorous military testing to receive this stamp. I think they may have gone to AMU per ALL military rather than miss leading every one thinking it was "Navy" only.
DOUGLAS F  "AMU" means that it is on the US Navy's "Approved for Military Use" list. In this particular case it means that it has been tested and approved for "Cold Water Use" by the US Navy.
Glenn G  Look in the smaller manual "erogatore abyss 22 navy ii" AMU: Authorized for Military Use.
JAN K  AMU. Authorized Military Use
MTN biker M  It's the test performed on the regulator "extreme cold" ice diving condition
RUPERT M  AMU stands for approved for military use. I like really like this system for cold water use but it feeds me too much air. This takes a lot of time to get use to and you must push back on the air supply to stop the excess air.
Dan S  I believe the stands for, "Authorized for Military Use".
RONALD S  Authorized for Military Use
