Description
Description
SCUBAPRO MK25 Evo / S600 Dive Regulator System combines an air-balanced first stage with an air-balanced second stage to deliver steady airflow with low work of breathing across a range of diving conditions. It provides reliable, consistent air delivery for scuba and underwater exploration, supporting comfortable breathing and dependable gear performance in varied water temperatures and depths.
Built for durability and precise control, the MK25 Evo first stage uses chrome-plated brass with Extended Thermal Insulating System (XTIS) to improve cold-water resistance and delay ice formation, while anti-freeze protection enhances breathing reliability in extreme temperatures. The S600 second stage features a rugged technopolymer housing with a stainless steel frame, a diver-adjustable inhalation effort knob, and a Venturi-Initiated Vacuum Assist (VIVA) switch. The system offers flexible hose routing via a swivel turret with four high-flow and one axial high-flow low-pressure ports, plus two opposing high-pressure ports for up or down orientation. External intermediate pressure adjustment enables quick tuning in the field, and the DIN connector type ensures compatibility with compatible scuba gear.
Features
Features
- Air-balanced flow-through piston in a chrome plated brass body provides constant airflow unaffected by depth, tank pressure, or breathing rate, supporting smooth scuba and diving performance.
- XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in underwater conditions.
- Anti-freeze protection increases breathing reliability in extreme water temperatures during scuba diving.
- Two opposing high-pressure ports allow the first stage to be positioned up or down, providing flexible setup for underwater gear.
- Four high-flow and one axial super high-flow low-pressure ports on a swivel turret maximize hose routing options for your diving configuration.
- External intermediate pressure adjustment enables quick tuning by technicians for consistent performance at depth.
- Air-balanced second stage valve smooths inhalation effort at varying depths and supply pressures.
- Second stage’s rugged technopolymer case with stainless steel frame offers durability and a modern look for scuba gear.
- Metal valve housing (barrel) is built to withstand years of aggressive diving.
- User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) switch for dive/pre-dive adjustments.
- Super-flow hose with an oversized bore delivers more air per inhalation for efficient underwater breathing.
- Orthodontic mouthpiece provides comfort and easy grip without inhibiting airflow during long dives.

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.
