The forged body of the 1st Stage FSR5, made from a single piece of material, features a thoughtful design tuned for best performance. Four medium pressure outlets, routed for optimum hose configuration, are complemented by a fifth, axial outlet for special configurations (sidemount, dual mount). The FSR5 is a closed DS system. The insulation from the surrounding environment together with the replaceable HP seat made of high quality ARCAP alloy makes it extremely durable and suitable for diving in cold water and contaminated environments.
FSR5 TUNGSTEN is coated with a layer of titanium, zirconium and chromium by PVD (physical layer deposition) technology, which gives it not only a luxurious matte appearance, but also superior protection against mechanical damage, corrosion and other harmful effects.
