IST O60 2nd Stage
Adjustable flow control
The IST O60 2nd Stage is designed for use in both warm and cold water. The housing is structured to create a pressure drop just before the mouthpiece. This ensures air is pulled towards the diver’s mouth directly after leaving the valve. In extremely cold water this feature also acts as a heat sink to prevent icing.
The side adjustment knob allows for easy adjustment of air volume delivery to suit the diver’s workload and preferences. The pre-dive / dive switch helps minimise freeflows at the surface.
