Description
The Cressi MC9 + Compact regulator combines a balanced diaphragm first stage with a compact and lightweight second stage for consistent and comfortable breathing performance. Featuring Cressi’s PressureSync technology, the first stage maintains stable intermediate pressure throughout the breathing cycle. The Compact second stage is designed to reduce jaw fatigue while offering simple airflow control via an adjustable Venturi system. With durable materials and a streamlined design, this regulator is built for reliability and ease of use in recreational diving. Great for use as a travel regulator due to the compact featherweight design of the second stage.
Also available in DIN.
