Brand: Mares
Located in: Essential Equipment, Regulators
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, givingvery 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.

Comments about Mares Mares Abyss 22 Regulator:

Mares makes some great dive equipment, and I’m exceptionally pleased with the total regulator. These regulators are extremely non-complicated and easy to repair. They follow in the footsteps of AMF Swimmaster’s MR12. The Abyss breaths like a dream in the shallows as well as at deeper than normal sport diving. Rem: Diaphragm first stages give little warning for last breath keep an eyeball on the pressure gauge.

I was impressed at how natural it was to breath with this reg - certainly a huge improvement on the Oceanic stuff the Dive school used.

I was surprised that it free-flows very easily. That's manageable, so the bottom line is I love my Mares reg!

Comments about Mares Mares Abyss 22 Regulator:

I've had this reg for four years, now. It replaced
a nearly 20-year-old MR12III (on mine, the 2nd stage is almost identical to the MR12III; it was succeeded by the "turbine-face" 2nd stage; which was itself succeded by the current "spaghetti
collander" style 2nd stage). Aside from the issues I have with it, which in reality are minor at worst, I swear BY this regulator...not AT it!

Comments about Mares Mares Abyss 22 Regulator:

Great look, breathes easy...which is the most important feature.

Great regulator, well built and sturdy. I wanted something good for both warm and cold water and this seems to be it. Also very serviceable, easy to find service people for this piece of equipment. Have used in the Caribbean, Bahamas and also in Thailand.

Only downside is that it can get heavy, both carrying to the divesite and also during the dive.

Service & Delivery comments:

Was assembled when delivered, wish it had included a low pressure hose.

Yes, I would recommend this to a friend

Comments about Mares Mares Abyss 22 Regulator:

Got it as a gift four years ago, to replace a 20-year-old MR12III, which was an awesome reg. Despite the fact that it will give you a dry throat, and the exhaust tee compromises keeping bubbles from getting in your way (while you're stationary; no biggie when swimming)for aerodynamics, I love this unit. It's very, very easy-breathing, and overall, quite fun to use. I highly recommend it for sport/recreational diving. (I understand it's great for just about any diving application, but you be the judge!)

Comments about Mares Mares Abyss 22 Regulator:

Well, this is the one for me! Excellent breathing (that's what it's for). Had no problems in colder water.
The only thing to remark is that it's a little heavy, so that's something to remember if you fly a lot. For me that has never been a problem and gives an overall sturdy and robust feeling to the reg.

Comments about Mares Mares Abyss 22 Regulator:

This is an excellent regulator, i have done more than 1200 dives with it and i only had it serviced by professionals 2 times. But the breathing at depth gets harder you feel sometimes like you are sucking the air. And it's not because it's used and abused, was always like that. I got used to it but i cannot say that it's the most comfortable breathing, specially after trying the scubapro s600/mk25 what difference! I won't say that my abyss is a bad regulator it has been my buddy for a lot of dives and never failed on me, but the air flow is not the best. I specially don't recommend it for extreme depths.

Comments about Mares Mares Abyss 22 Regulator:

Hi! Hope this review helps! I have had this reg for about 9 months and dove at least 60 dives with it. It is well built and easy to use. It breathes absolutely perfectly, and despite some comments I saw, the exhaust manifold hasn't bubbled up any of my picture taking moments. It doesnt have any adjustment switches and doesn't need them; and in turn you don't pay hundreds more for any gimmicks. I found the factory bite block was a little small so I got a moldable one and switched them out. Besides that there are no complaints. As I said, it breathes great. Also, it doesn't have the free flow problems I see with other types of regs..less air wasted is good :) I would definitely recommend this reg to friends and one friend did buy the same one and has also enjoyed it. I would buy it again!
