Known for its low work of breathing, this regulator set provides smooth air delivery and steady airflow across a wide range of conditions, making it a dependable component of your scuba gear.
The 1st stage uses chrome-plated brass in a piston design for robust, dependable performance, while the 2nd stage features a balanced S Series construction with a reinforced technopolymer casing for durability and light weight. With an INT connector and Nitrox compatibility up to 40%, this regulator pairs with a wide range of underwater gear configurations for diving in different environments.
Designed for various water temperatures—from cold to warm—the system includes anti-freeze protection and the XTIS Extended Thermal Insulating System to maintain stable airflow. It offers two high-pressure ports and multiple low-pressure ports to support flexible hose routing in your scuba setup, delivering consistent performance across dives.
SCUBAPRO’s regulator system emphasizes smooth inhalation and exhalation, offering ultra-fast breathing response and instantaneous air delivery as part of a reliable underwater breathing experience.

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.
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.
