MC11 1st Stage Only Overview
The MC11 1st Stage Only is designed for divers who want a compact, lightweight and high-performance first stage for warm-water diving. Its balanced diaphragm system supports consistent breathing as cylinder pressure changes, while Cressi PressureSync helps reduce the typical pressure drop at the beginning of inhalation.
With 2 high-pressure ports and 4 medium-pressure ports, the MC11 allows practical hose routing for a clean and efficient regulator setup. Its low weight makes it especially suitable for travel, recreational diving and streamlined gear configurations.

MC11 1st Stage Only FAQs
What is the MC11 1st Stage Only used for?
The MC11 1st Stage Only is used as the first stage in a compatible scuba regulator setup. It connects to the cylinder valve and supplies intermediate-pressure air to the second stage and accessories.
Is the MC11 1st Stage Only suitable for cold water?

The MC11 is the standard compact warm-water version. The MC11 SC adds a sealed chamber system for improved protection of the internal working components and cold-water-ready performance.
Is this a complete regulator?
No. This product is the first stage only. It needs to be paired with compatible second stages, hoses and accessories as part of a complete certified regulator configuration.
