MK11 EVO FIRST STAGE

The SCUBAPRO MK11 EVO is a balanced diaphragm first stage in a forged brass body, more compact than the MK11 it replaces. Metal fins on the body improve thermal exchange, and plastic bumpers protect the finish from the knocks a first stage takes in a kit bag. An innovative double spring layout is what keeps it small without giving up reliability.

Two high pressure ports sit on a 15-degree angle, which makes high pressure hose routing easier and gives a transmitter somewhere sensible to sit. All four low pressure ports are high-flow, so airflow and hose routing options are both improved over the previous generation. Intermediate pressure is externally adjustable, letting a technician fine-tune the first stage without stripping it. It is CE certified to EN 250A for all diving conditions, including extreme cold water.
