Unmatched Core Performance: The DST First Stage

At the heart of this premium package is the renowned DST first stage. Built with an over-balanced diaphragm design, it provides superior breathing performance at depth. The system is entirely environmentally sealed, expertly keeping out water and contaminants while preventing ice formation during extreme cold-water dives. To enhance your comfort, the swivel turret body features smartly angled ports that support perfectly optimised hose routing, keeping your gear streamlined and snag-free.

Customised Comfort: The XTX50 Second Stage

The XTX50 second stage is a masterpiece of diver-adjustable engineering. Because it is pneumatically balanced, you enjoy a smooth, effortless draw of air regardless of your depth or tank pressure. You have total control over your breathing experience with an integrated venturi lever and an adjustable cracking control knob. Furthermore, the innovative Comfo-bite™ mouthpiece virtually eliminates jaw fatigue, allowing you to focus purely on your aquatic adventure. Additionally, this can be converted from a right-handed hose configuration to a left-handed one by our authorised service technicians before shipping, find out more here.
