Scubapro Mk17 EVO 2 / S600 + Octopus R105

First Stage:

• The new design allows it to be considerably smaller and lighter than the MK17 EVO and MK19 EVO.
• The design is based on a forged brass body and dry chamber with a dual spring arrangement for increased compactness and reliability.
• The sealed offset diaphragm design makes it the ultimate compact first stage for cold water or contaminated submersible conditions.
• The balanced diaphragm with marine-grade◊ chrome-plated brass body allows you to obtain air consistently and effortlessly whatever the depth, tank pressure or breathing rate.
• The dry chamber is completely isolated from the environment with a unique double membrane system that prevents the entry of contaminated water. The edge is designed to enhance heat exchange, making the first stage resistant to cold water.
• Two opposing high-pressure outlets positioned at a 15-degree angle allow the first stage to be positioned up or down, facilitating optimal hose/transmitter placement.
• Due to the position of the high-pressure outlet, a transmitter adapter is not required.
• Weight (g): INT 232 : 797g ; DIN 300 : 572g
• Intermediate pressure (bar): 9.2-9.8.

Second Stage:

• Balanced valve reduces inspiratory effort at different depths and supply pressures.
• The heavy-duty front cover and housing, made of reinforced technopolymer, withstand many years of diving in the most demanding conditions.
• The larger membrane  provides maximum breathing sensitivity.
• It includes an easy-to-grip inhalation effort control knob and diver-adjustable VIVA (Venturi-Initiated Vacuum Assist) lever.
• The high-flow hose has an oversized inner section to increase airflow with each inhalation.
• Compact, ultra-comfortable orthodontic mouthpiece is easy to hold and does not reduce airflow.
• CE marked according to the latest European standard EN250A for all diving conditions, including diving in extremely cold water.

R105 Octopus Features:

• Classic downstream valve design for dependable breathing performance
• Dive/pre-dive VIVA switch helps control free flows.
• Metal valve housing is built rugged and increases overall reliability.
• Reversible hose attachment makes it easy to use on pony or deco tanks.
• High-viz yellow super-flow hose is 39in/1m long and features an oversized bore that allows more air to flow on each inhalation.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
