About Mares Rover 12S Regulator

Rover 12S is an excellent choice for intensive use at a Diving Center and for recreational divers who demand reliability. The balanced diaphragm first stage uses the Mares Tri-material valve; the medium-size second stage features a cover made of soft material that makes it easy to push the purge button, even when wearing gloves. The latest technologies offer easy, natural, regular breathing.

The all chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The Rover 12S uses Tri-Material Valve Technology. This patented technology created to optimize performance, safety and reliability. The valve is covered with a hard Polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty" PU) reaches new levels of durability.

Another unique feature of the first-stage is the Dynamic Flow Control (DFC). The DFC system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler more reliable second stage. No type of manual adjustment of the second stage is necessary due to the consistency derived from a first stage that guarantees a stable flow of air, even under extreme conditions.

The techno-polymer second stage has superior performance. The patented mesh design of the second stage cover reduces the pressure of water flowing onto the regulators diaphragm and minimizes free-flow. Even in a strong current it eliminates the need for a knob to de-tune your air delivery system- advance technology through basic physics.

All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

Mares Rover second stage incorporates the Fluid Dynamic Deflector, developed after in-depth studies and tests of fluid dynamics, is engineered to receive and properly direct the airflow from the bypass tube to the mouthpiece. Combined with the VAD system it delivers very natural and effortless breathing. Rover 12S has a 3/8" threaded 31.5" (80 cm) hose and comes with a limited lifetime warranty.

Questions about this item:

Michael D  Is there a DIN conversion available for the 12S?
earl w  what is the "work of breathing" on this regulator ?
JOEY W  This is my first regulator, but I would consider it at entry level. There is a getting used to period where it feels like your having to work to breath, but I got used to it and don't even think about it anymore.
