Or the vest could make h_ll of a noise when activated, this (without my knowing) might even be a wake-up call to the swb victim, I have read several texts on the swb, as I recall all of them state that the vocal cord tightens to prevent any water from entering lungs preventing emidiate drowning, when the surface of divers face feels a breese of wind, it calls the diver back to consiusness since the brain understands this a sign of the airways being free of the water....I think they even suggested that you shouldŽnt use cpr before trying to gently blow on the face of the victim.
please do not trust a word of this or take what I write as anything other than what I recall reading, there are texts to be found on the net written by people who know what they are talking about, personaly hate the topic, it freaks me out.........just wanted to suggest sound on the vest not write an essay
