Scubapro MK11/C370 Diving Regulator System

Scubapro MK11/C370 Diving Regulator System comes from Scubapro, and it's part of our Amazon-linked regulator lineup rather than something we stock ourselves. Marine-grade chrome-plated brass body, reduced size and weight for travel. Air-balanced diaphragm first stage, constant airflow regardless of depth/pressure. A balanced first stage keeps your breathing effort consistent whether the tank is full or nearly empty, and regardless of depth. Sealed internal parts improve cold-water performance. Heads up: this specific listing checks out on Amazon, not through FGSS directly. We're an Amazon Associate, so a qualifying purchase here earns us a small commission -- it doesn't change your price.
