With full CE certification and performance IST's R860 Diaphragm Regulator is on par with the finest regulators on the market. The R860 is well suited for stringent cold water, deep dives, demanding profiles, and can also be fine-tuned for smooth responsive gas delivery. There are two high pressure ports, and four intermediate ports mounted on a swivel turret for easy hose routing.
The O60 second stage is equipped with a metal balancing tube and an adjustment knob. They are able to meet heavy breathing demand with ease and in extremely cold water they also act as heat sink to prevent icing. Ease of breathing is achieved by a purposely shaped housing interior, which is designed to create a pressure drop in the area just before the mouthpiece. This means air gets pulled towards the diver’s mouth directly after leaving the valve. The volume of air leaving the valve can be fine-tuned by the adjustment knob on the side of the O60 at any time so the diver can choose to to breathe conservatively, or to open the valve up for more air in physical demanding situations.
