Mares has incorporated the top of modern regulator technology into the 28XR-HR underwater regulator. The first stage uses the innovative concept of the balanced diaphragm, which is operated by a double piston. All ecologically sealed using AST - Auto Sealing Technology. This also guarantees perfect sealing against the possible entry of sand or particles, especially in cave diving or in polluted waters. This proves further true in technical diving, for the possibility of removing it in the water without flooding it. The rotating turret with vertical low pressure outlet and 4 more low pressure outlets make it usable in all configurations. Its flexibility allows it to be used: on the double tank, in stages and in sidemount configuration.
The second stage with technopolymer body, simple and ultralight, provides excellent performance. A large side knob allows you to adjust the breathing force even when wearing thick neoprene gloves. You can adjust the "hard" second stage when not in use, and make it "softer" when in use.
