The MK17 EVO 2/S600 features a newly designed sealed diaphragm first stage and an air-balanced second stage with years of proven performance under its belt. The S600, with its rugged reinforced technopolymer casing and stainless steel front face and ring, provides a steady, effortless flow of air, regardless of depth or water temperature, in the most demanding dive conditions.
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.
