Exceptionally light weight, incorporating state-of-the-art technology. Integrated bypass and next-generation technopolymers, this new, ultra-compact second stage with two-component construction, the V16 Proton and MR12 Proton are an ideal choice for recreational diving.
V16 First Stage
Mares V16 First stage is the latest version of the balanced diaphragm regulator.
In addition to all the characteristics that have made the success of this Mares product, including the DFC system, the V16 is also equipped with the now famous SCS (Spherical Core Seal) valve for longer life. The piston shuts off the flow of air by means of a highly durable titanium hemisphere, which is unassailable by oils or grease. The valve seat is made from a special high strength technopolymer. Two HP ports and four LP ports, pre-positioned for rational hose routing.
The shock and scratch-resistant black coating is unique and makes the V16 the perfect companion for hundreds of dives.
Proton second stage
Light weight, ruggedness, high performance and simple construction.
These are the distinguishing features of this brand new and ultra-compact second stage. Two-component body for a unique look, coupled with superior mechanical characteristics.
Integrated VAD by-pass system, for effortless, natural breathing under all conditions. Coverplate with ultra-light alloy ring, anodized and incorporating the “mesh-grid” system for maximum performance.
”Super-soft” hose and a new orthodontic mouthpiece for unparalleled comfort.
