Let’s take a look at some of the features of the First Stage

  • The Rovers 12s use a balanced diaphragm first stage to deliver air from the dive tank to the second stage. This ensures that the performance of the regulator remains the same at any recreational dive depths and tank pressure,  delivering consistent breathing efforts through your dive. The first stage allows for 2 high-pressure ports and 4 low pressure which is perfect for most hose routing. 
  • The first stage also uses Mares’ “Tri-Material Valve Technology” which is made from brass, soft polyurethane,  and heavy-duty polyurethane.  Meres claims the combination of these materials ensures that the regulator delivers optimum performance during servicing.  ( You can watch the mares Tri-Material Valve Technology video to get a better understanding of who this works).
  • This regulator also features Mares DFC System which minimizes the drop in intermediate pressure on inhalation, which in-turn increases the regulator performance on deeper dives or high demanding situations (like swimming up current). This is why Mares say their second stages does not require manual adjustment.  (You can also watch the Mares DFC system Video to learn how this works and also see it in action).

Now let’s look at some of the features of the Second Stage

  • The second stage uses a standard downstream valve with no user adjustment. Mares claims that because the first stage delivers a constant flow of air to the second stage in almost all diving conditions, there is no need for the diver to make any adjustments to breathing efforts, and many divers that had first-hand experience with this regulator claims this to be true.
  • The second stage is also very easy to purge even while wearing thick gloves. This is mainly because the entire front of the regulator is made of soft rubber-like material.
  • Mares also claims the second stage breathes naturally, and easily, and will reduce the formation of ice in cold water diving due to its’ Vortex Assisted Design (VAD) system.  This system bypass air coming from the low-pressure house directly to the mouthpiece, offering superior performance and initially very natural breathing, even for an unbalanced second stage.
