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. Even though the Divesoft BOV 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. It is designed to be versatile, it is possible to connect it to the Divesoft patented MAVs or to implement a built-in ADV. 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. Divesoft originally supplied their BOV configured with the Divex Lars mouthpiece, but since 2020 has shipped configured with a generic comfo-bite mouthpiece. If you prefer to use a retaining strap with your rebreather, Divesoft recommends the AP Diving Rebreather Safety Mouthpiece (aka Gag Strap).
