The bailout valve can immediately switch from rebreather to open circuit bailout in an emergency. There is no need to remove the mouthpiece from your mouth in such a dangerous situation as hypoxia, hyperoxia or hypercapnia. You make just one easy movement to switch to open circuit. Our BOV is really unique. It is a game-changer on the market thanks to its functional design and features. Even though it combines a standard mouthpiece with second stage regulator, it stays light and compact. It is neutrally buoyant which prevents jaw’s fatigue during long dives.

Modular design allows you to choose between a standard mouthpiece or opt for a connector for a variety of full-face masks. Supplied together with two wide and two narrow clamping rings, including of BOV extension knob.
