MK17 EVO2/S600

• Sealed balanced diaphragm design makes for the ultimate compact first stage for cold water or contaminated diving conditions.

• Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.

• Dry chamber is completely environmentally sealed with a dual diaphragm system that keeps out contaminated water. The rib is designed to enhance heat exchange, making the first stage cold water-proof.  

• Two opposing high-pressure ports positioned on a 15º angle allow the first stage to be positioned either up or down, plus provide an optimal hose/transmitter layout.

• S600 second stage's air balanced valve smoothes out the inhalation effort at varying depths and supply pressures.

• Rugged reinforced technopolymer second stage case and front cover with stainless steel frame looks good plus is extremely durable.

• Metal valve housing (barrel) is able to withstand years of aggressive diving.

• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

• Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.

• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

• CE certified to EN250A European Standards for all diving conditions, including extreme cold water.

• Full regulator system package includes the R105 Octopus.
