Offering full CE certification and performance that is on par with the finest regulators on the market, the IST Premium Balanced Diaphragm DIN Style Regulator Bundle consists of an R-8 first stage and O-60 second stage, with included large bore intermediate pressure hose. This combination is well suited for deep dives in tropical to cool water conditions and can handle demanding profiles, but it can also be fine-tuned for smooth, responsive gas delivery in more relaxed conditions.
The IST R8 first stage, one of the best ever tested by Scuba Diving Magazine’s ScubaLab, is a balanced diaphragm design. Two high pressure ports and four intermediate ports are mounted on a swivel turret for easy hose routing.
The O-60 second stage is equipped with a metal balancing tube and a pair of user adjustments: the dive/pre-dive thumb lever detunes the reg to minimize freeflows on the surface, and the breathing resistance knob lets you regulate airflow as you descend to greater depths. Comes with our high-spec, large bore intermediate pressure hose (max. service pressure @ 34.5 BAR / 500psi) which flows sufficient breathing air even when the demand is heavy. Includes comfort mouthpiece with bite tabs.
The R860 is designed for divers of all skill levels, and for water conditions ranging from tropical to cool.
