Dive Rite - XT1/XT4 Regulator w/ 28 inch Hose

The XT Regulator welcomes a new generation of regulator performance at Dive Rite. An elite performer, the XT's advanced, patented design earns top marks from Mike Ward of Dive Lab. With work of breathing at less than 1.0 J/l, the XT performs right alongside premier regulators on the market today.

XT1 First Stage Regulator

• Balanced first stage provides consistent gas flow regardless of depth and tank pressure
• Five low pressure ports and a swivel turret achieves optimal hose routing
• HP ports are angled 90-degrees from the DIN/Yoke fitting which gives the perfect angle for hose routing
• Environmentally sealed to protect against internal corrosion, contaminants and freeze
• Available as DIN or Yoke

XT4 Second Stage Regulator:

Dive Rite - XT4 Second Stage

The XT4 is Dive Rite's premier adjustable and pneumatically balanced 2nd stage regulator. Offering serious performance and an exceptionally low work of breathing in a compact design, the XT4 will be there for you on your most demanding dives. Compared to the XT2, the size of the XT4 has been reduced, and the exhaust T has been trimmed and angled for a more streamlined package perfect for technical divers.

The front rubber cover is protected by a cast aluminum exoskeleton providing extreme durability and an elegant appearance. Sandblasted and hard coat annodized gives durable matte finish and provides the ultimate abrasion resistance.  The XT4 is accented with a metal adjustment knob, logo badge, and finned heat exchanger. At just 9.4 oz (266 g) it is lightweight for travel but maintains a substantial feel in the hand.

The XT4 includes a user adjustable, secondary micro spring adjustment in the end of the main adjustment knob. This allows independent adjustment of the spring preload and can be used to easily fine tune the cracking pressure without disassembly of the 2nd stage. This can be useful for those who prefer a higher cracking pressure, or to make minor adjustments as the low pressure seat breaks in.

The finned heat exchanger is designed to improve cold-water performance. The internal components of the second stage can get very cold due to adiabatic cooling as the pressure of the breathing gas drops from intermediate pressure to ambient pressure at the second stage. In cold-water diving, the temperatures can become low enough to freeze the moisture from your exhaled breath and cause the regulator to stop functioning correctly. The heat exchanger combats this issue by helping to warm the internal metal components of the regulator to the surrounding water temperature.

Additional features include an updated low pressure seat design that improves performance and requires less frequent adjustment. The XT4 can be setup for left or right handed hose routing. The regulator is assembled using industry standard oxygen compatible materials and assembly processes and is suitable for use with oxygen enriched gas mixtures.
