Key Features:

MK17 First Stage:
The MK17 is a balanced diaphragm first stage engineered for consistent air flow even in cold, silty, or contaminated waters. Its environmentally sealed design prevents water from entering the internal components, ensuring reliable performance and reducing the risk of freezing in cold conditions. The dual high-pressure and multiple low-pressure ports provide flexible hose routing for both recreational and advanced divers.

S620TI Second Stage:
Constructed from lightweight technopolymer with a titanium air barrel, the S620TI offers reduced weight, excellent corrosion resistance, and high-efficiency airflow. Its compact design minimizes jaw fatigue while maintaining Scubapro’s signature breathing performance. The high-flow exhaust system and precision air-balanced valve help deliver smooth, powerful inhalation even at depth.

Air Balanced Valve:
The S620TI’s air-balanced valve ensures consistent breathing effort regardless of depth or remaining tank pressure, providing a stable and comfortable breathing experience during the entire dive.

Dual Exhaust Valve:
The dual exhaust system improves exhalation efficiency while reducing bubble interference, offering clearer breathing and better visibility during sensitive moments like photography or safety stops.

Adjustable Inhalation Effort:
Divers can fine-tune breathing resistance with a simple adjustment knob, allowing personalized airflow control to match conditions, preferences, and dive style.

Compact & Ergonomic Design:
The streamlined second stage is designed for reduced jaw fatigue and improved comfort during long dives. Its lightweight materials and balanced design make it an excellent choice for frequent divers and travelers.
