PRODUCT DETAILS
Tough enough for the UK. Smart enough for any dive. Smooth enough to forget it’s even there.
The Apeks XTX 50 + DST Regulator System is built for divers who want durability and intelligent control. At its core is the Apeks DST First Stage, featuring a 360° rotating turret that transforms hose routing into something cleaner, safer, and effortlessly adaptable. Perfect for decluttered single-cylinder rigs, versatile stage setups, and streamlined twin configurations.
Performance increases with pressure — literally. The over-balanced diaphragm design pushes medium pressure gas to your hoses faster than the surrounding water pressure rises as you descend, delivering powerful, stable airflow even at depth. Add in the environmental dry seal system, and you’ve got contamination defence and freeze resistance baked into your gear. Muddy entries, colder temperatures, silty lakes and temperamental seas are simply part of the design brief, not a performance concern.
The XTX 50 second stage delivers breathing that feels unfairly easy, thanks to its pneumatically balanced valve that minimises inhalation effort and maximises consistency. Its hallmark? You choose exactly how it breathes. The dedicated cracking pressure adjuster gives you fingertip authority over opening resistance, letting you tune each inhale to match conditions, preferences, or dive tasks.
Big gloves? No problem. The oversized venturi lever with soft-grip finish makes airflow control ridiculously easy to find and adjust, even when chilled or distracted. The 2-stage progressive purge delivers a soft whisper of gas for delicate tasks like deploying surface markers or buoyancy bags, and a full power blast for rapid regulator clearing.
Where comfort meets science: moulded components include active antimicrobial protection, guarding against harmful bacteria, fungi and viruses. The silicone exhaust valve enhances exhalation efficiency, while the jaw-fatigue-eliminating Comfo-bite™ mouthpiece keeps you comfortable long after others start blaming their regulator. A patented heat exchanger captures ambient water warmth to counteract cooling from gas expansion, supporting dependable performance in cold dives.
Whether you're shore diving the coast, navigating inland training sites, or dropping onto historic wrecks, this is gear that works with you — not against you.
The bottom line?
A regulator that’s built rugged, breathes refined, routes clean, and adjusts to you.
Breathe better. Dive further. Stay in control.
