Description
The Scubapro MK17 EVO2 S620Ti Dive Regulator delivers reliable breathing for scuba diving in cold or challenging water. This system pairs a redesigned forged first stage with a compact, lightweight profile to reduce weight and bulk while maintaining performance. The MK17 EVO 2 first stage features a forged body that is smaller and lighter than the MK17 EVO and MK19 EVO, supporting dependable airflow across demanding underwater conditions.
The S620 Ti second stage blends high performance with a modern, lightweight design. Titanium components and a reinforced technopolymer casing contribute to durability in underwater environments, while a titanium inlet tube offers ultra-lightweight operation and corrosion resistance. An efficient air circulation path—highlighted by a large air shower cover—promotes smooth breathing, and the exhaust T-piece provides improved bubble deflection to keep visibility clear. The diaphragm is optimized to match the size of the S600 for consistent airflow in a range of diving conditions. This scuba gear supports Nitrox up to 40% and is suitable for warm, cold, and temperate water.

Frequently Asked Questions
ScubaPro MK25 EVO vs MK17 EVO2: which first stage should I choose?
The MK25 EVO is a balanced piston first stage — it delivers the highest airflow and instant response, and it is the choice of many performance-focused and warm-to-cold water divers. The MK17 EVO2 is a sealed diaphragm first stage — its internals are isolated from water, which makes it the traditional pick for very cold water and silty or salty conditions with less maintenance sensitivity. Both are excellent; choose the MK25 EVO for maximum performance and adjustability, the MK17 EVO2 for a fully sealed set-and-forget workhorse.
Should I order my ScubaPro regulator in DIN or yoke?
Yoke (INT) is the most common fitting on rental tanks in North America and the Caribbean, so it is the simplest choice if you mostly dive at resorts. DIN screws directly into the tank valve, is rated for higher pressures, and is standard in Europe and technical diving — and a DIN regulator can use a simple adapter on yoke tanks, which makes DIN the more flexible long-term choice for traveling divers. ScubaPro sells both versions, and a yoke regulator can later be converted to DIN by an authorized dealer using a genuine ScubaPro conversion kit (DIN owners going the other way simply use a DIN-to-yoke adapter — no conversion needed).
What is the difference between the MK25 EVO and the original MK25?
The EVO generation added ScubaPro's XTIS (Extended Thermal Insulating System), which improves freezing resistance in cold water, along with updated materials and finishes. The core balanced-piston design that made the MK25 famous is unchanged — the EVO is the same performance with better cold-water protection.
Is the S620Ti second stage good for cold water, and what does the Ti mean?
Ti refers to the S620Ti's titanium components — the inlet tube and barrel are full titanium, making the second stage ultralight and highly corrosion-resistant, housed in a rugged fiber-reinforced technopolymer casing. It is the successor to ScubaPro's legendary S600: smaller and lighter, but with the same-size diaphragm for effortless airflow in all conditions. Paired with the MK25 EVO first stage, the system is cold-water rated.
How often does a ScubaPro regulator need service?
ScubaPro's official recommendation is a full service by an authorized ScubaPro technician every 2 years or 100 dives, whichever comes first. If you dive heavily (100+ dives a year), ScubaPro recommends an inspection every 6 months and an overhaul annually. Staying on schedule also keeps you eligible for ScubaPro's Parts For Life program — free service parts for the original owner when the regulator is registered and purchased as part of a qualifying package from an authorized dealer. As an authorized ScubaPro dealer, we can help with registration and service when it is due.
