Mares has incorporated the top of modern regulator technology into the 28XR-HR underwater regulator. The first stage uses an innovative balanced diaphragm which is operated by a double piston. AST - Auto Sealing Technology guarantees perfect sealing against the possible entry of sand or other particles, especially in cave diving or in polluted waters. The rotating swivel turret with 1 vertical low pressure port and 4 low pressure ports means it can be used in all configurations.

The second stage with a technopolymer body which is simple and ultralight, provides excellent performance. A large side knob allows you to adjust breathing force, even when wearing thick neoprene gloves. 2nd Stage - For stage, main backmount, back-up backmount or “hard breathing” backmount use - Extreme cold water use - Adjustable breathing comfort system allows the diver to control inhalation effort - VAD system with “curved” bypass for natural high air flow - Simple, performing, ultralight technopolymer body - PAD – Pneumatically Assisted Design - Oversized purge button - Soft rubber lp hose 1st Stage - Shiny chrome metal body - Natural DFC on all LP ports - TBP Dry Kit - environmentally sealed for better performance on cold water dives - AST - auto sealing technology - 4 LP ports on a swivel turret - A 5th additional in-line LP port - 2 symmetrical HP ports with a 10° port angle for perfect HP hose positioning - NR - G5/8 connection, 300 bar (DIN) - NX - M26 connection, 300 bar (nitrox)
