If your refering to people trapped in motor vehicles don't worry about it. They hold a lot of air in the movies and TV but reality is quite different.renpirate:We would be diving in a river, so I can see the point about snags with a slung bottle. As I look at the Tiger Mount, I can't help but wonder, if doubles with an isolation valve and independent regs might be an option. This ofcourse affects the selection of BC, which is why I mention it here. Surface supplied air will not me an option, at least for a while.
Gary, would the pony be used as a pass off air source to a trapped victim in rescues or are they always unconcious by the time you get there?
If for example you did happen to have a concious person trapped and you did get them out, chances are neither of you would make it to the surface concious or alive.
