Product Information
The SCUBAPRO MK2 EVO/R195 Dive Regulator System is an entry-level to intermediate INT (yoke) scuba regulator built for divers who want simple, dependable breathing performance in cold, temperate, or warm water. It pairs a chrome-plated brass, piston-style MK2 EVO first stage with 1 high-pressure and 4 low-pressure ports to a metal-housed R195 second stage, and this listing includes a colored mouthpiece and hose protector kit for personalizing the regulator or marking gas mixes.
Who it is for
This regulator suits new divers who want an economical, dependable setup as well as veteran divers who need a reg that handles everything from Caribbean reef dives to cold Great Lakes wrecks. The MK2 EVO's cold-water design also appeals to divers who travel between warm and cold destinations without swapping gear. The colored mouthpiece and hose protector kit also lets tech divers easily distinguish their gas mixes.
Key details
The MK2 EVO first stage uses a downstream piston design with a chrome-plated brass body, 1 HP port, and 4 LP ports. SCUBAPRO's patented XTIS (Extended Thermal Insulating System) isolates the mechanical components from cold water using an insulating spring bushing and coating, insulating piston bushing, insulating sleeve, and antifreeze cap, and an oversized piston increases airflow by 15 percent. A stainless steel removable orifice simplifies maintenance. The R195 second stage is an unbalanced, R Series design with a metal valve housing and reinforced technopolymer casing, a classic downstream valve, a VIVA switch to control free flow, a super-flow hose with a larger inner diameter, and a reversible hose attachment for use on deco tanks. The system is rated for nitrox mixes up to 40 percent, uses an INT connector, weighs 2.35 lb, and ships with a 39-inch hose.
Compatibility and sizing
The mouthpiece and hose protector kit is made of PVC and is offered in Purple, Red, Yellow, White, Pink, and Orange to match the rest of a diver's gear or to color-code gas mixes. It is compatible with the entire range of currently offered SCUBAPRO second stages.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
What colors are available for the MK2 EVO/R195 mouthpiece and hose protector kit?
The kit is offered in six colors: Purple, Red, Yellow, White, Pink, and Orange. It is made of PVC and lets you personalize the regulator's look or color-code gas mixes on tech dives.
Is the MK2 EVO/R195 good for cold-water diving?
Yes. The MK2 EVO first stage uses SCUBAPRO's patented XTIS system, which isolates internal mechanical components from cold water with an insulating spring bushing, piston bushing, sleeve, and antifreeze cap. This design is specifically built to resist freezing, so the regulator performs across cold, temperate, and warm water.
What is included when I order the MK2 EVO/R195?
Each order includes the complete MK2 EVO/R195 regulator system, which combines the first and second stage, along with a printed product manual. This listing also includes a mouthpiece and hose protector kit in the color you select.
How many ports does the MK2 EVO first stage have?
The MK2 EVO first stage has 1 high-pressure port and 4 low-pressure ports. The high-pressure port typically feeds a dive computer or SPG, while the low-pressure ports supply the second stage, octopus, BCD inflator, and dry suit inflator as needed.
