is the distance that separates them. how could that possibly be? but what we really don't know is the strength or relative weakness of each of those detections. and that would have a lot to do with the relative distance between the detector and the pinging device. now, if there was one thing pinging, why would it be all over the map? it is the strangeness of the aco acoustics, you want to have all the detection pings. you will have a cluster. >> but miles, if they only have one beacon sending signals, if
