This may sound stupid but I've never used on of the auto inflation vests and am wondering something. If you would happen to be caught in a heavy rain and get soaked, would that set the vest off? I'm only asking because I can't find anything that explains how these vests work for automatic. Seems that if they work by an area getting saturated, it would be possible for it to go off when you wouldn't want it to. I've been soaked already to the point of dripping water from clothing. I'm just curious as I want to buy another boat (started looking) and am thinking of getting two of these type vests.
