Engineered for tough conditions, the MK17 EVO 2 / G260 Regulator System offers compact comfortable breathing performance through icy depths or silty wrecks. The MK17 EVO 2 is smaller and lighter weight than its MK17 EVO predecessor and the MK19 EVO, thanks to a forged body, dry chamber with a twin spring layout for increased reliability and compactness. Teamed with the G260, with its metal internal components, high-flow exhaust valve, diving controls and reversible hose attachment, you’ve got a top-performing regulator system for the most extreme diving conditions. The MK17 EVO 2 / G260 Regulator System is your partner in precision, performance, and confidence beneath the surface.
Features
-
Compact Sealed First Stage
Sealed balanced diaphragm design makes for the ultimate compact first stage for cold water or contaminated diving conditions.
-
Effortless Airflow
Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
-
Environmentally Sealed Dry Chamber
Dry chamber is completely environmentally sealed with a dual diaphragm system that keeps out contaminated water. The rib is designed to enhance heat exchange, making the first stage cold water-proof.
-
Optimized Hose Routing
Two opposing high-pressure ports positioned on a 15º angle allow the first stage to be positioned either up or down, plus provide an optimal hose/transmitter layout.
-
Smooth Breathing Performance
Air balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.
-
Rugged Second Stage Design
Rugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
-
Extreme Cold Friendly
Metal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.
-
Adjustable Breathing Controls
A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
-
High-Flow Exhaust Valve
High-flow exhaust valve reduces exhalation for better overall breathing comfort, and the reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
-
Super-Flow Hose
Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
