MK25 EVO FIRST STAGE
\nThe air-balanced flow-through piston in a marine-grade chrome-plated brass body provides continuous airflow regardless of depth, tank pressure, or breathing rate. The patented Extended Thermal Insulating System (XTIS) thermally isolates the internal mechanism from the environment, improving cold water resistance by 30% and delaying ice formation in extremely cold water conditions without compromising breathing performance. Key components of the insulation system are highlighted in blue. The spring insulation jacket, body insulation bushing, anti-freeze cap, larger body, and cap thread combine seamlessly with the XTIS system to improve cold water performance. Anti-freeze protection significantly increases breathing reliability when diving in extremely cold water. Two opposing high-pressure ports allow the first stage to be positioned high or low. Four high-flow low-pressure ports and one ultra-high-flow axial port on a rotating turret increase the hose’s routing options. External intermediate pressure adjustment allows technicians to fine-tune performance quickly and easily. The DIN version features a dual-compound handwheel with an ergonomic shape and soft grip on a sturdy black nylon frame.
\nDIN 300 weight: 570g <\/p>\n
S600 SECOND STAGE
\nThe balanced valve alleviates inhalation effort when diving at varying depths and pressures. The metal valve housing can withstand years of diving
\nin extreme conditions. User controls include an inhalation effort adjustment knob and a dive-pre-dive lever for adjusting the Venturi effect (VIVA – Venturi Initiated Vacuum Assist).
\nThe superflow hose features an oversized bore that allows for greater airflow with each inhalation. The ultra-comfortable orthodontic mouthpiece is easy to grip but does not restrict airflow.
\nCE certified in compliance with the latest European standards EN250A for all diving conditions, including diving in extremely cold water.
\nWeight (without mouthpiece): 200 g <\/p>\n
