It can take a long time to get an up-to-date response or contact with relevant users.
interesting design ,so similar to a spare air just new design the chest mount might be a little cumbersome when loading a gun and if thats compressed air then would you not need a pressure stop rather than a steady ascent? but interesting concept
 
it looks like a better option for scuba guys and it is less cumbersome than a pony bottle. it just looks quite small.

5 minutes of just breathing at rest would be a lot less swimming and almost no time if you were sprint swimming
 
I wasn't thinking of using it for swimming, mostly i thought it would be awesome for that one time you get tangled or caught on something. Even one more minute at that point could save your life.
