This new addition to the Mares line combines the simplicity and reliability of the balanced diaphragm MR12 1st stage with the toughness of the Rebel 2nd stage. Ideal regulator for Dive Store and recreational divers looking for an economical air or nitrox scuba regulator with uncompromising performance.

Ultralight technopolymer technology
Exclusive technopolymers give the regulator exceptional durability sturdiness and make it very lightweight.

DFC – Dynamic Flow Control
DFC makes it possible to minimize the intermediate pressure drop during the inhalation phase, improving regulator performance and reducing breathing effort.

VAD – Vortex Assisted Design
The air coming from the hose passes through the second stage valve and is conveyed directly to the mouthpiece through the by-pass tube. There is a "vortex" movement in the airflow inside the by-pass tube (low pressure area). This low pressure helps hold down the second stage diaphragm while inhaling, thus increasing the regulator sensitivity. Regulators with the VAD system offer improved performance and allow for very natural breathing. One of the main causes of ice forming in the regulator is the expansion of air inside the second stage case, which causes an abrupt drop in temperature. With the VAD system, this expansion takes place inside the by-pass tube and mouthpiece, reducing the likelihood of icing.

Mesh-grid
The mesh design of the second stage cap optimizes the flow of water on the second stage diaphragm and minimizes the chance of free-flow.
