MK11 EVO First Stage

Product Description

The SCUBAPRO MK11 EVO First Stage is a compact, air-balanced diaphragm regulator designed for reliable performance in all diving conditions, including cold water environments. Built with a durable brass body and integrated thermal exchange ribs, this first stage improves heat transfer to reduce the risk of freezing during demanding dives.

Compared to its predecessor, the MK11, the MK11 EVO features a more compact design and improved breathing performance. The innovative dual-spring mechanism enhances reliability while keeping the first stage lightweight and efficient.

The housing includes protective synthetic bumpers to help prevent scratches during use and transport. Two angled high-pressure ports (15°) improve hose routing, while the four high-flow low-pressure ports ensure optimal airflow and flexible configuration options.

The externally adjustable intermediate pressure allows technicians to fine-tune performance quickly and easily. The MK11 EVO is CE-certified for all diving conditions, including extreme cold water, in accordance with the EN250A standard.
