Mares Abyss 22 Review: Delivering Record-Breaking Performance

Mares Abyss 22

The Mares Abyss 22 has been getting great reviews for quite some time now for its high performing balanced diaphragm first stage and very responsive second stage.

Mares claims that the Abyss 22 gained its reputation for being reliable by setting many records, such as the deepest solo dive to -313m as well as 101 divers breathing simultaneously for 40 minutes from a single first stage.

The first stage has also been recently upgraded by stripping all unnecessary metal while still keeping its structural integrity.

This gives the regulator a distinct look while allowing it to deliver better performance than its predecessor.

Now Let us Take A Look At The Record Breaking First Stage

Mares Abyss 22 first Stage

To help reduce the overall weight of the MR22 First Stage, Mares has stripped it of all unnecessary metal without compromising the structural integrity of the regulator.

This reworking of the design increases the surface area of the first stage, giving it even better thermal characteristics on cold water dives – making an already reliable regulator even more reliable.

It also uses Mares’ patented “Dynamic Flow Control” (DFC) system, which minimizes the drop in intermediate pressure on inhalation, especially in extremely demanding dive conditions.

This is one of the main reason this first stage was able to break the record for the most number of divers breathing from a single first stage. You will never have to push the regulator to these extremes, but it is assuring to know it’s there when you need it.

The overall performance, safety,  and reliability have also been enhanced by the use of Mares patented Tri-Material Valve.

Thanks to this special technology the head of the valve always provides a perfect seal, even under extreme conditions, and prevent uncontrollable free from occurring even under the most stressful conditions.

It is also equipped with 2 high-pressure ports at fixed angles and 4 low-pressure ports, as well as Nitrox compatible to 40% oxygen right out of the box.

Second Stage Features

TMares Abyss 22 second stage regulatorhe Mares Abyss second stage features an all metal construction. This provides great thermal properties, preventing the formation of ice that can cause unwanted free flows when diving in colder temperatures.

It also uses a downstream demand valve system. Mares claims the DFC system, which minimizes the drop in the intermediate press during inhalation, they were able to use a simple and reliable valve system without sacrificing performance.

There is also no user controls on the second stage. This is due to “Mares Vortex Assisted Design” (VAD) System and Mesh Grid Technology.

The VAD System uses a bypass tube to deliver air directly to the mouthpiece. This creates a vortex inside the second stage that keeps the diaphragm down during inhalation, providing lower breathing resistance at any depth.

And, a mesh grid incorporated into the front cover lowers the effect that water flow has on the diaphragm, helping to prevent free flows in strong currents.

The Abyss second stage is now outfitted with a new Super Flex hose that is more durable and flexible, adding a great margin of safety as well as increasing the freedom of movement which can help decrease jaw fatigue.
