The MK25 EVO\/G260 is just such a system. The MK25 EVO delivers an ultra-fast breathing response, great sensitivity and extra-high airflow, making it the ultimate do-it-all first stage for all water temperatures. The G260 is the most imitated air-balanced second stage of all time. It features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eAir-balanced flow-through piston in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.\u003c\/li\u003e\n\u003cli\u003ePatented XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.\u003c\/li\u003e\n\u003cli\u003eAnti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.\u003c\/li\u003e\n\u003cli\u003eTwo opposing high pressure ports allow the first stage to be positioned either up or down.\u003c\/li\u003e\n\u003cli\u003eFour high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options.\u003c\/li\u003e\n\u003cli\u003eExternal intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.\u003c\/li\u003e\n\u003cli\u003eAir-balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.\u003c\/li\u003e\n\u003cli\u003eRugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.\u003c\/li\u003e\n\u003cli\u003eMetal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.\u003c\/li\u003e\n\u003cli\u003eA diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive\/pre-dive switch prevents free flows in cold water or when used as an octopus.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eWhat our Experts
