        I know you were making a joke here but believe it or not when our 
dive team is looking for a recovery item in separate groups, divers blow the 
whistles underwater to alert the other divers that the object of the search 
has been found.  After hearing the whistle, divers surface and proceed with 
the next objective or evidence collection.  I know what you are thinking... 
whistles don't work underwater... right?  If you cup your hands and blow the 
whistle down into your air pocketed hands, it works fine and the sound 
travels great!  This has saved us allot of bottom time searching for a victim 
that has already been found by another group.
