Its system features internal parts that are sealed from the elements, increasing reliability and performance. The polished chrome forged brass body features identical high pressure and low pressure ports on each side so you can hook it up to your tank in either the up or down position while maintaining the same port layout. Also, two of the low pressure ports are high-flow, delivering about 15 percent more air than the standard low pressure ports. This means lots of effortless airflow with every breath. Air-balanced design with diaphragm and a professional-quality chrome-plated copper housing provides constant, effortless airflow regardless of depth, tank pressure and breathing rate. Fully sealed housing made of seawater resistant copper so that the internal mechanism is not affected by water and contamination and the system performs better in cold water.
