The Scubapro MK17 EVO 2 / S620 Ti regulator system offers compact and comfortable breathing performance, making it an unbeatable choice for cold or silty water diving. The MK17 EVO 2 is a significant upgrade from its predecessor, the MK17 EVO, and the MK19 EVO. It features a new forged body and a dry chamber with a twin-spring layout, enhancing reliability and reducing size and weight.
The S620 Ti second stage incorporates the best features of Scubapro’s renowned S600 into a modern, state-of-the-art design. Smaller and lighter than the S600, it retains the same-sized diaphragm, ensuring exceptional performance and effortless airflow in any dive condition. The full titanium inlet tube is ultra-light, while the large purge cover improves water circulation, and the exhaust tee enhances performance by directing bubbles out of the diver's field of view. This advanced regulator system is designed to deliver top-notch performance and comfort in challenging environments.
