Electronic Keyfinder Keychain

Never lose your keys again!! The way it works is simple, you simply attach your keys to the keychain and when you misplace them simply whistle and the sonic keyfinder will display a flashing light and and beep tone sequence so you can both see and hear where the noise is coming from. It is a very sleek looking keychain as well, lightweight and compact and operates off of two watch type batteries and includes two replacement batteries.
