Scubapro has recently introduced the MK17 EVO 2 regulator first stage, a state-of-the-art regulator engineered for superior performance in cold and challenging underwater environments. This new first stage is an enhancement of the highly acclaimed MK17 model. It can be paired with the S620 TI, S600, or C370 second stage and is expected to be available for shipping by the end of 2024.
The MK17 series has long been SCUBAPRO’s premier sealed diaphragm first stage. In its latest iteration, the MK17 EVO 2 elevates performance, reliability, compactness, and freezing resistance, establishing itself as one of the finest SCUBAPRO sealed diaphragm first stages to date. More compact and lighter than its predecessors, the MK17 EVO and MK19 EVO, the MK17 EVO 2 features a new forged body and a dry chamber with a twin spring layout for enhanced reliability and compactness. The two newly designed HP ports are positioned at a specific 15-degree angle to facilitate easier HP hose routing, eliminating the need for a transmitter adapter. A SCUBAPRO transmitter can now be directly attached to the first stage.
The New 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 unique dual diaphragm system that keeps out contaminated water. The rib is designed to enhance heat exchange, making the first stage cold waterproof.
◊ 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.
◊ Weight: INT 232: 797g; DIN 300: 572g
◊ Intermediate pressure (230 bar): 9.2-9.8
