Engineered for tough conditions, the MK17 EVO 2 / G260 Regulator System offers compact comfortable breathing performance through icy depths or silty wrecks. The MK17 EVO 2 is smaller and lighter weight than its MK17 EVO predecessor and the MK19 EVO, thanks to a forged body, dry chamber with a twin spring layout for increased reliability and compactness. Teamed with the G260, with its metal internal components, high-flow exhaust valve, diving controls and reversible hose attachment, you’ve got a top-performing regulator system for the most extreme diving conditions. The MK17 EVO 2 / G260 Regulator System is your partner in precision, performance, and confidence beneath the surface.
