Divers seeking a dependable and straightforward air delivery system will love the Scubapro MK11 / S270. This easy-to-use, compact, and sturdy setup offers a balanced diaphragm MK11 that ensures consistent airflow regardless of depth, tank pressure, or breathing rate. The robust S270 features a smooth breathing performance in a scratch-resistant design, built for years of heavy use.

Ideal for recreational divers in temperate waters, the MK11 first stage regulator boasts an environmentally sealed diaphragm-based design, keeping sensitive components safe from cold water and debris. This makes it a popular choice among cold-water and contaminated-water divers. Scubapro's diaphragm first stages are packed with patented, balanced technology for rapid flow and excellent performance.

The MK11, made from marine-grade chromed brass, features a balanced diaphragm and Thermal Insulating System (TIS) for reliable performance, even in cold water. With an over-balanced design, it provides superior breathing at greater depths. It comes with two 7/16" HP ports and four 3/8" LP ports, including two High Flow Ports (HFP) for demanding dives.

The lightweight S270, crafted from fiberglass-reinforced nylon and a polyurethane (PU) outer layer, is highly durable and comfortable. Its second stage has a balanced valve and a techno polymer barrel with metal threads, preventing ice crystals from forming in extreme cold. The air-balanced valve ensures smooth inhalation, while the dive/predive switch is glove-friendly. The compact exhaust tee reduces exhalation effort, and the second stage includes a reusable mouthpiece clamp and 3/8" LP hose.

Weighing 30.1 oz (853.3g), the regulator is nitrox-ready up to 40% oxygen and comes with a manual. Experience the simplicity and reliability of the Scubapro MK11 / S270 on your next dive!
