The ideal system for tech divers and cave explorers, perfect for cold waters and with optimal routing options.
The G260 is a 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 left-right hose attachment option makes it ideally suited for tech diving configurations.
MK17 EVO First Stage:
Air balanced 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.
More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
Substantial increase in airflow -- 6900 l/min versus 6500 l/min -- includes improved balance of air supply pressure.
Two high pressure and four high-flow ports maximize air delivery and hose routing options.
High-flow performance is available from all four LP ports which are configured for optimum hose routing.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
Available in a 3364psi/232bar INT configuration.
Weight: INT 232 - 30oz/850g.
Airflow at 2900psi/200bar: 6900 l/ min - 230 SCFM.
Intermediate pressure (psi/bar): 130-142/9.0-9.8.
G260 Second Stage:
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.
