The MK19 EVO/G260 has been specially developed for technical and cave diving. The MK19 EVO is a fully sealed system that is extremely resistant to freezing and contamination of the internal mechanism. It has a dry ambient pressure chamber with a double spring and also a swivel head so that you can optimally connect the low-pressure hoses. In combination with the G260 with its metal components, high-flow exhalation valve, adjustment options and the hose on the left or right, this is a first-class regulator for the most extreme conditions.

FIRST STAGE MK19

• Specially developed as the ultimate first stage for diving in cold or contaminated water. The version is considerably smaller and lighter than the original MK19.
• Air-balanced diaphragm with professional-quality chrome-plated copper housing provides consistent, smooth air delivery regardless of depth, tank pressure or breathing rate.
• The housing is completely sealed so that the internal mechanism is not affected by water and contamination.
• The dry chamber has a double spring, making it even more compact and reliable.
• Thanks to the two high-pressure ports opposite each other, the first stage can be used upright or upside down and an additional hose/transmitter can be connected.
• The swivel head features four High Flow low pressure ports and an axial Super High Flow low pressure port so you can connect the hoses as desired.
• Compact, lightweight and superbly breathable - this first stage continues the SCUBAPRO regulator tradition.
• First stage ideal for recreational, technical, professional and military divers.
• Weight (g): INT 232, 885 grams; DIN 300, 665 grams
• Air flow at 200 bar: (l/min): >6,900 Medium pressure: 9.2-9.8 bar

SECOND STAGE G260

• The air-balanced valve ensures optimal breathing comfort at different depths and with varying cylinder pressure.
• The nylon fiberglass second stage features SCUBAPRO's largest housing and diaphragm and responds incredibly quickly, no matter how you are in the water.
• Thanks to the front cover ring made of dark anodized aluminum, the second stage is scratch-resistant without being heavier.
• The metal components, such as the metal valve seat and the metal inlet pipe, make the second stage more resistant to freezing during diving under extreme conditions.
• The exhalation valve has a high flow, which means that exhaling requires less effort and the second stage breathes more pleasantly.
• With the button that allows the diver to regulate the inhalation resistance, the air delivery can be adjusted to depth, water conditions and personal preference.
• The VIVA (Venturi-Initiated Vacuum Assist) lever for Dive or Pre-Dive mode prevents blowing in cold water or when used as an octopus.
• The hose can be connected on both the left and right for technical configurations.
• The Superflow hose has an extra large diameter so that more air is supplied during inhalation.
• The extremely comfortable, orthodontically shaped mouthpiece fits well in the mouth and does not hinder air flow.
• Air flow at 200 bar/2900 psi: 1800 l/min.
