The Apeks XTX50 with Yoke and DST is a high-performance regulator system for scuba diving. The DST (Double-Sealed Turret) first stage features four medium-pressure ports mounted on a swiveling turret, allowing for optimal hose routing and the use of more accessories. The XTX50 second stage includes an adjustable inhalation effort and venturi control, which divers can use to fine-tune their breathing experience under different diving conditions.
