MK17 EVO2 / C370 GRAPHITE + R105 OCTO

This regulator set pairs the SCUBAPRO MK17 EVO 2 first stage with the C370 second stage in its graphite finish and adds the R105 as an alternate air source. The MK17 EVO 2 is a sealed balanced diaphragm first stage with a dry chamber, twin spring layout and dual diaphragm system, which keeps cold and contaminated water away from the inner mechanism. Its two high pressure ports sit on a 15-degree angle and accept a SCUBAPRO transmitter directly.

The C370 second stage is air-balanced, with a diver-adjustable inhalation effort knob, a coaxial dive/pre-dive lever for VIVA and a large purge button, housed in a fibreglass-reinforced nylon casing. This version carries an impact-resistant polymer front frame in graphite rather than the stainless steel one, and that frame can be swapped for any of the C370 colour frames, which are sold separately. The R105 octopus is a classic downstream design with a metal valve housing and a reversible hose attachment on a 1 m high-visibility yellow Super-Flow hose.

First stage: MK17 EVO 2, sealed balanced diaphragm, forged chrome-plated marine-grade brass, 4 high-flow low pressure and 2 high pressure ports, 860 g in INT 232, intermediate pressure 9.2 to 9.8 bar (133 to 142 psi). Second stage: C370 with graphite polymer colour frame, air-balanced. Octopus: R105 on a 1 m yellow Super-Flow hose. Connections: DIN 300 and INT 232.
