SCUBAPRO MK17 EVO2 / S620Ti + R105 Octo Overview

The SCUBAPRO MK17 EVO2 / S620Ti + R105 Octo combines a sealed MK17 EVO2 first stage, premium S620Ti primary second stage and R105 alternate air source. The MK17 EVO2 is a balanced diaphragm first stage with a dry chamber, helping protect the internal mechanism from cold water, silt and contaminants.

The first stage includes 2 high-pressure ports and 4 low-pressure ports, giving divers practical hose-routing options for a pressure gauge, transmitter, BCD inflator hose, primary second stage and octopus setup. Its sealed design makes it a strong choice for warm, temperate, cold or silty diving environments when correctly configured and serviced.

The S620Ti primary second stage is compact, lightweight and air-balanced for smooth breathing at varying depths and cylinder pressures. Its full titanium barrel offers excellent corrosion resistance and reduced weight, while the large diaphragm, diver-adjustable inhalation effort and VIVA Venturi control let divers fine-tune breathing comfort.

The included R105 Octopus provides a dependable backup air source in a classic downstream design. Its Dive / Pre-Dive VIVA switch helps reduce unwanted freeflow risk, while the reversible hose attachment supports flexible setup by a qualified technician.

This product includes the MK17 EVO2 first stage, S620Ti primary second stage and R105 Octopus only unless your supplier states otherwise. It does not include a pressure gauge, dive computer, transmitter, BCD, cylinder, inflator hose, regulator bag, service parts, tools or other accessories unless supplied separately. Regulator setup and servicing should be completed by a qualified dive equipment technician.
