The MK17 EVO 2/S620 Ti regulator system from Scubapro is designed for divers who want compact design, extreme reliability and effortless breathing – even in cold water. The combination of the fully sealed MK17 EVO 2 first stage and the lightweight, air-balanced S620 Ti second stage delivers stable airflow in all conditions.
The regulator set is ideal for both cold Nordic waters and warm holiday destinations, and is aimed at divers who want high performance in a compact and durable setup.
MK17 EVO 2 – sealed diaphragm first stage for Scandinavian conditions
The MK17 EVO 2 is an air-balanced diaphragm first stage with a fully sealed dry chamber that effectively protects against dirt, salt and contaminated water. The dual diaphragm system combined with heat-exchanging fins ensures high resistance to freezing, making the first stage especially suitable for cold-water diving. The air-balanced construction provides smooth and effortless breathing regardless of depth, tank pressure and breathing demand.
Optimized hose routing and flexible configuration
The two high-pressure ports are positioned opposite each other at a smart 15° angle, allowing the first stage to be mounted either upward or downward while ensuring streamlined hose routing. Together with four low-pressure ports, this provides maximum flexibility for regulator, octopus, inflator and additional equipment.
S620 Ti second stage – lightweight and built for long-term use
The S620 Ti second stage delivers extremely smooth and effortless breathing in all conditions. The air-balanced valve ensures consistent airflow at varying depths and pressures, while the large diaphragm provides high sensitivity in a compact housing. The valve housing is made of titanium, making it lightweight, corrosion-resistant and extremely durable. The reinforced technopolymer casing with stainless steel front frame ensures excellent durability.
Full adjustability and maximum comfort
The S620 Ti features adjustable inhalation resistance and the Venturi Initiated Vacuum Assist (VIVA) system, allowing you to fine-tune airflow and reduce the risk of freeflow. The compact Hi-Flow mouthpiece mounted on an enlarged air inlet improves airflow and provides excellent comfort.
Ready for all diving conditions
The regulator set is suitable for warm, temperate and cold water and supports nitrox mixes up to 40%. It is CE certified to EN250A standards, ensuring safe operation – even in extreme cold-water conditions.
