For those that aren't familiar with the term, a BOV is a Bail Out Valve some rebreather divers use instead of having a redundant bail gas supply (I don't use a BOV as I prefer a DSV on its own due to jaw fatigue). This video is for the shrimp BOV some HH (Hammerhead rebreather) divers use. The video is about 5 minutes long, a completely automated process. For perspective, these BOVs are priced between $800 - $900 each. I'm sure Herman will enjoy this video...
