Designed to offer smooth and reliable breathing in all conditions, it is the ideal choice for divers seeking high performance at an accessible price point — from tropical waters to cold water diving.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eFirst Stage – DS4 Balanced Diaphragm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDS4 balanced diaphragm system:\u003c\/strong\u003e ensures constant intermediate pressure regardless of cylinder pressure, providing uniform breathing throughout the dive.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntermediate pressure over-balancing effect:\u003c\/strong\u003e as you descend deeper, the gas pressure in the hose progressively increases relative to the surrounding environment, improving breathing performance at depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry Seal system:\u003c\/strong\u003e a watertight seal isolates the main spring from water, preventing ice buildup in cold water dives and protecting internal mechanisms from silt and contaminants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 HP ports and 4 angled MP ports:\u003c\/strong\u003e the port arrangement allows for optimal hose routing, with the ability to configure the regulator for both right-hand and left-hand use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-quality satin chrome finish\u003c\/strong\u003e, resistant to marine corrosion.\u003c\/li\u003e\n\u003cli\u003eAvailable in

reduced inspiratory effort, regardless of depth and residual cylinder pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-function XTX purge button:\u003c\/strong\u003e large and easy to operate even with gloves, it offers a progressive two-stage purge — side pressure for a reduced, controlled flow, central pressure to maximize the purge effect.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Venturi lever:\u003c\/strong\u003e with a soft rubber grip, it allows you to adjust the incoming airflow to optimize breathing on the surface (– position) and underwater (+ position), reducing the risk of free flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInhalation effort control knob:\u003c\/strong\u003e allows the

surrounds the valve mechanism and dissipates the cold generated by gas expansion, drawing heat from the surrounding water — essential for preventing freezing in cold water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilicone exhaust valve:\u003c\/strong\u003e improves breathing performance by reducing exhalation
