If you dive deep, dive cold, or often find yourself on silty bottoms, the MK19 EVO/G260 is the regulator for you. While you don’t need to dive less-than-pristine waters to appreciate this system, it’s a great choice for cold water or harsh conditions, which is why tech divers and cave explorers just love this reg. The compact MK19 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. The G260 is the most imitated air balanced second stage of all time. It features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer. Put them together and you’ve got a winner.

MK19 EVO

MK19 EVO is designed to be the ultimate first stage for cold water or contaminated diving conditions.

• Ideal first stage for avid recreational, technical, professional and military divers.
• Latest design makes it substantially smaller and lighter than the original MK19.
• Air-balanced first stage diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the inner mechanism and is extremely resistant to freezing.
• New dry chamber is equipped with a double spring making it more compact and reliable.
• Two opposing high pressure ports allow the first stage to be positioned either up or down, plus provide for an optimum hose/transmitter layout.
• Swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port to maximize hose routing options for technical diving layouts.
• CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.

G260

Aimed at technical divers, this system can face any dive situation with rock-solid performances and outstanding reliability.

The G260 is a new balanced adjustable second stage featuring metal components for excellent cold water resistance (inlet tube, orifice, inhalation control knob and hose connector). It's high performance makes it a choice for all demanding divers and it will be the natural choice for G250 fans. The new left-right hose attachment option makes it ideally suited for tech diving configurations.

• Nylon fiberglass design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
• Anodized aluminum front cover ring adds resistance without adding weight.
• Metal components provide increased resistance to freezing when diving in extreme water conditions.
• High-flow exhaust valve reduces exhalation for better overall breathing comfort.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes.
• Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
• Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
• Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
• Weight: 275g.
• Airflow at 200bar: 1800 l/min - 64 SCFM.
• Maximum low pressure: 14bar.
