SCS Spherical Core Seal System - patented
First stage valve with spherical seal for superior durability. The valve is optimally specular, unassailable by oil or grease and resistant to any form of corrosion: it does not deteriorate. The valve seat, constructed from a special extra-tough technopolymer, results in a tight seal.

DFC Dynamic Flow Control - patented
Mares' first stages feature the exclusive DFC (Dynamic Flow Control) system, which minimises the intermediate pressure drop during the inhalation phase, thereby considerably improving regulator performance in terms of breathing effort and inhalation resistance.

VAD Vortex Assisted Design - patented
TiPlanet, Ruby, Abyss and Orbiter second stages offer the unique Mares patented VAD (Vortex Assisted Design) system. This system is unique and allows smooth breathing at all depths and its operating principle is very simple. The air coming from the hose passes through the second stage valve and is conveyed directly to the mouthpiece through the by-pass tube. Within the mouthpiece, the air flow undergoes a "vortex" effect. Whenever this swirl occurs, the core of the vortex creates a low-presure area. This low pressure helps keep the second stage diaphragm down while inhaling, thus increasing the regulator sensitivity.

Pivoting Deflector - patented
During the inhalation phase, the deflector positions itself in such a way as to maximise the Venturi effect. During the exhalation phase, it automatically returns to the rest position, in order not to obstruct the flow of exhaled air.

Mesh Grid - patented
Coverplate design, which disperses the water flow around the 2nd stage diaphragm, reduces the likelihood of free-flow. The calibrated holes allow a large amount of water to flow through, while at the same time reducing undesirable dynamic effects, even when swimming against a strong current. The Orbiter 2nd stage also features the mesh grid system on the side walls.

Metal Inserts - patented
Metal foil inserts, set within the second stage body, act as heat exchangers. The principal characteristic of this patented feature is it's anti-freeze function, which, while retaining the light weight of a technopolymer, permits rapid dispersion of the cold produced by expansion of the inhaled air.

Ultralight two-component technopolymer technology - patented
The second stage body, moulded from high strength technopolymers, is over moulded with a special elastomer that confers a unified appearance to the component as well as high resistance to abrasion.

Cold water diving
The following technical features make Mares regulators ideal for diving in punishing cold-water conditions:
Balanced diaphragm first stages
The balanced diaphragm first stage design has amply proved itself ideal for cold water diving. For particularly demanding conditions, it can be fitted with a CWD kit, which completely isolates all of the moving parts of the first stage from contact with the water.
Second stages with VAD system
One of the principal causes of icing in regulators is the expansion of air inside the body of the second stage. With the VAD system, this expansion takes place inside the bypass tube and mouthpiece, reducing the likelihood of icing.
