Most military organisations run an escape-and-evade course, during which their personnel are trained to avoid getting caught by forces in pursuit of them.
Today’s invention is for anyone being chased by a team of trackers with dogs, eg downed pilots…
It consists of a small, silent catapult with which the user can fire clay pigeon-like projectiles in random directions.
As each one lands, its thin outer skin cracks and releases a taught rubber band so that additional, internal clays spring out and fly for perhaps 10m in random directions.
The clays are nested to several levels so that they end up a long way from the user.
Each clay is heavily impregnated with human scent compunds.
The effect is that a pack of hounds is effectively misdirected away from their quarry.
