2nd Stage Shut Off
Great for use with rebreathers or as an shutoff for bailout regulators to prevent free flow.
Having a charged cylinder at all times reduces the need to open valves during rebreather bailouts. However, it is all too common for divers to inadvertantly lose gas from free flowing second stage regulators without even realizing it. Couple this with high flow or scooter diving and you could very easily trickle hundreds of PSI out throughout your dive.
The addition of a slide isolator allows the user to leave the tank valve in the open position. In the event of a bailout the isolator is quickly slid to the open position while the diver deploys the 2nd stage.
