I bet when my brother-in-law got trapped under his tractor (tipped sideways down a soaked road embankment) that he had a sidearm with this in it. A car drove by and saw it, luckily stopped and got help. No lasting damage, but it could have been bad if he was out in a field. I can think of a dozen other situations in farmland where it would be a good idea if you can't reach someone on a radio.
