The 72X first stage is compact and incredibly robust. The first stage body is forged from brass, chrome-plated and finished with a 'pearl' surface. There are eight low-pressure ports: four horizontal and four vertical. All eight are equipped with 'Natural DFC' for high airflow in all conditions. The configuration options for technical and recreational diving are endless. The two high-pressure ports are pre-oriented for optimal use. The 72X first stage is equipped with Mares Auto-Sealing Technology (AST), which provides excellent protection against the intrusion of water or unwanted substances. A very simple mechanical solution keeps the internal mechanism dry and free from obstructions, thus providing superior reliability.
