28XR - HR

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. Its flexibility allows it to be used: on a double tank, in stages and in a sidemount configuration.
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.
