MK17 EVO/S620Ti + R105 OCTO:
Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
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.
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.
S620Ti second stage's air balanced valve smooths out the inhalation effort at varying depths and supply pressures.
Rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is able to withstand years of aggressive diving.
Full titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
Large diaphragm fits inside a more compact second stage casing for maximum breathing sensitivity.
User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
Exclusive compact Hi-Flow mouthpiece is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort.
CE certified to EN250A European Standards for all diving conditions, including extreme cold water.
