Scubapro MK17 EVO/S600 Regulator Stage 3 Set

*Stage 3 sets come with 1st stage, 2nd stage and octo*

Teaming Scubapro’s best-selling second stage with its environmentally sealed first stage creates a reliable air delivery system for all diving conditions.The MK17 EVO is engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism.  This total sealing system also allows for a dry ambient pressure chamber which works to prevent freezing, provides better protection and improves performance, ensuring trouble-free operation no matter how cold or murky the water gets.

The set includes a highly reliable R195 octopus with an extra-long visibility hose and reversible hose attachment.

FIRST STAGE:

• Air balanced diaphragm in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
• Two high pressure and four high-flow low pressure ports maximise air delivery.
• High-flow performance is available from all four low pressure ports, which are configured for optimum hose routing.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Chrome-plated marine grade brass body is able to withstand years of aggressive diving.

SECOND STAGE:

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Metal valve housing (barrel) is able to withstand years of aggressive diving.
• User controls include a diver-adjustable inhalation effort knob and VenturiInitiated Vacuum Assist (VIVA) dive/pre-dive switch.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.

OCTO:

• High visibility yellow cover makes it easy to see when it comes time to share air with a buddy in need.
• Rugged reinforced technopolymer casing is fitted with a large diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
• Classic downstream valve comes with a VIVA switch to control free flows.
• Metal valve housing is built rugged and increases overall reliability.
• Yellow super-flow hose is 39in/1m long and features an oversized bore that allows more air to flow on each inhalation.
• Reversible hose attachment makes it easy to use on deco tanks.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
