I picked up a Ozark trail (Coghlan's) Multifunction Whistle a Wally Mart (for $2.94). The black plastic whistle is pea-less and much louder than I expected. On top there is a button compass, on the bottom, there is a thermometer, and in the middle is a little plastic fold out magnifier. There is also a snap hook for attaching to your pack, key ring, zipper pull, ect.
Everything seems to work well. I thought someone might be looking for something like this for the kids or for their suvival packs. Just thought I'd pass it along.
