One of the best "which hand" electronic devices, it is the smallest, and most reliable. At its core It is a magnet detector, so it can be used to find any item that can have a magnet imbedded in it.

While the best psychic in the world can only guess whether a coin is in someone's left or right hand 50% of the time, Espionage grants you the ability any psychic would desire. It allows you to not only determine the audience's choice, but also information they themselves are unaware of! They choose which hand to hide the coin behind their back, and you can pinpoint its location and whether it's heads or tails-even the spectators won't know!
