MIND MOLESTER. The �Mind Molester� is an instrument of creative electronic harassment. It is an electronic chirping device that can drive your victims nuts trying to figure out what it is and where it�s at. You can drive someone crazy in their own house or disrupt an entire office. Your victim(s) will become obsessed, awaiting the next chirp to try to determine its location, completely disrupting their normal activities. Just connect this device to a 9-volt battery and plant it in an appropriate location. The �Mind Molester� produces a one-second electronic chirp about once every 4 minutes. Due to the chirp�s duration, frequency, and sound characteristics, it�s a very, very difficult, time-consuming, frustrating and maddening task to locate the unit. And even if they find it, they�ll have no idea what it is. The number of effective locations to plant the �Mind Molester� is limited only by your imagination. Of course, this device is for use on deserving subjects only. Size: 1" x 1.75". Chirp frequency: 2000Hz.
