ScubaPro MK17 EVO First Stage Regulator

MK17 EVO is a premium high performance balanced diaphragm first stage by ScubaPro. Compact in size thanks to the smaller dry ambient pressure chamber and spring, this regulator comes with bulletproof inner parts. It also features a streamlined body constructed of machined marine-grade chrome.
The MK17 EVO is packed with patented features, including the Thermal Insulating System (TIS), which keeps the first stage from freezing up and malfunctioning in cold water conditions. Engineered specifically for harsh environments, this regulator has an environmentally sealed system, which means that its internal components are protected from the elements so neither water nor pollutants can get inside the inner mechanism. Additionally, this allows for a dry ambient pressure chamber which works to prevent freezing, provides better protection and improves performance, ensuring trouble-free operation no matter how cold or murky the water gets. Such an impressive feature set and premium quality materials result in a fantastic overall performance.
