IST O-50 Octopus
The IST O-50 Octopus is a very simple octopus designed for easy usage. Reliable and robust, it uses time-proven, easy to service down-stream valve. Coupled with IST’s high-spec, large bore intermediate pressure hose, it supplies more than enough airflow even when breathing demand is high.
The light-action purge button is large and easy to access. But it is slightly harder to press. A feature that is appreciated by divers who are looking to prevent unwanted free flow.
The pre-dive/dive switch is easily located on top of the second stage housing. Great for preventing free-flow while the diver is on the surface.
