Technical divers will love the solid breathing performance and proven reliability of this notable regulator combo. The air-balanced piston-style MK25 EVO is consistently ranked as the top-performing first stage on the market. The G260 is the most imitated air balanced second stage design of all time. Made with a rugged reinforced technopolymer casing and metal internal components to ensure excellent cold-water performance, it also offers a left-right hose attachment option, making it a great choice for tech diving configurations. Both first and second stages feature a Black Tech scratch-resistant coating that protects against the ravages of salt water and corrosion. It’s a workhorse system for the most demanding dive conditions.
