Scubapro MK17 EVO 2 / C370 Regulator + R105 Octopus

Scubapro MK17 EVO 2 / C370 Regulator with R105 Octopus

The Scubapro MK17 EVO 2 / C370 Regulator provides a compact, lightweight system perfect for exploring dive sites around the globe. 

This redesigned setup features a sealed-diaphragm first stage and a dry chamber with a twin-spring layout. Additionally, the C370 second stage now offers optional diver-changeable colour frames in six vibrant colours. Consequently, you can personalise your gear in seconds while enjoying elite performance.

The MK17 EVO 2 includes two high-pressure ports set at a 15-degree angle to make hose routing much easier. Furthermore, the compact C370 offers convenient user controls, such as a diver-adjustable inhalation-effort knob. This system also features a coaxial dive/pre-dive lever and a large, easy-to-activate purge button. As a result, divers gain precision breathing control and reliable air delivery in any recreational scenario.

The R105 Octopus offers dependable breathing performance in a classic downstream design with a dive/pre-dive VIVA switch and reversible hose attachment.

What's in the box?

The package includes the C370 Second Stage in Black/Graphite with a regulator hose, the MK17 EVO2 first stage and R105 Octopus with a yellow 1m octopus hose. These components ensure you have everything needed to start your next underwater adventure with confidence.

DIN or A-clamp first stage?

Most of our divers prefer DIN fitting on the 1st stage regulator. A DIN regulator has a threaded post which screws into the inside of a DIN tank valve and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank.

YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened.

Both regulators seal to the scuba tank through an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators with their own o-ring.

DIN fittings are commonly accepted as more secure, but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
