Scubapro MK17 or S600 Regulator, DIN with Yoke Adaptor updated

MK 17 First Stage The MK17's balanced diaphragm offers you peace of mind with it smooth breathing mechanisms and maximum performance that doesn't diminish as your air supply does. SCUBAPRO outfitted the MK17 with a dry ambient chamber, which means no water will sneak into the 1st stage and wreak havoc while you're at depth. The Thermal Insulating System (TIS) & anti-freeze system prot ect the internal mechanisms from freezing, even in icy diving environments. S600 Second Stage Because of the S600's versatility, it can meet the diver's needs as frequently as the diver changes dive sites. The S600 is constructed of a chrome-plated brass and technopolymer valve housing, a linear air-balancing valve, and a top notch air-balancing system. This regulator's air-balanced linear-flow valve allows the diver to use less energy while breathing underwater; it makes breathing during a dive as simple as well, breathing in and out.
