Description
SCUBAPRO's MK25 EVO DIN 300/S620 Ti Dive Regulator with Mouthpiece delivers reliable air delivery for scuba and diving across conditions. This all-weather system combines a balanced first stage with the S620 Ti second stage to support underwater exploration. The DIN 300 connection provides a secure setup, and its design emphasizes resistance to freezing, smooth inhalation, and instant air delivery for dependable gear performance.
With chrome-plated brass for the first stage and full titanium components in the second stage, the regulator balances durability and lightweight feel. XTIS thermal protection helps guard against ice formation in cold-water dives, and anti-freeze features support breathing stability in challenging environments. The port layout includes two high-pressure ports and five low-pressure ports on a swivel turret, with external intermediate pressure adjustment for technician-tuned performance. The S620 Ti second stage uses an air-balanced valve and a Hi-Flow mouthpiece for comfortable airflow, while compatibility with all SCUBAPRO second stages ensures versatility for different diving setups. Nitrox support up to 40% is available, and the complete regulator weighs approximately 2.6 lb.
Features
Features
- First stage design: Air balanced flow-through piston in a chrome-plated brass body provides constant airflow unaffected by depth, tank pressure, or breathing rate.
- Thermal protection: Patented XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism to improve cold-water resistance and delay ice formation.
- Anti-freeze protection: Enhances breathing reliability in extreme cold-water conditions.
- Port configuration: Two high-pressure ports and five low-pressure ports on a swivel turret for flexible hose routing.
- Adjustability: External intermediate pressure adjustment allows quick tuning by technicians.
- Second stage performance: Air balanced valve provides smooth inhalation across depth and pressure changes; Hi-Flow mouthpiece improves airflow and comfort.
- Construction: Full titanium barrel and components offer lightweight durability and anti-corrosion properties; rugged reinforced housing.
- Breathing sensitivity: Large diaphragm in a compact second stage with easy-grip inhalation control and VIVA lever for airflow optimization.
- Versatility: Compatible with all SCUBAPRO second stages; DIN 300 connection; Nitrox up to 40%.
- Weight: Approximately 2.6 lb for the complete regulator.
- Materials: 1st stage: chrome-plated brass; 2nd stage: titanium components.
- Temperature range: Designed for cold, temperate, and warm water conditions.

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.
