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 MK17 EVO 2 is more compact and lighter weight than its MK17 EVO predecessor and the MK19 EVO with a NEW forged body, dry chamber with a twin spring layout for increased reliability and compactness. 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.
MK17 EVO FIRST STAGE
NEW design allows it to be substantially smaller and lighter than the MK17 EVO and the MK19 EVO.
Design is based on a forged brass body and a dry chamber with a twin spring layout for compactness and reliability.
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 diaphragm 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.
Due to the high-pressure port positioning, a transmitter adapter is not needed.
