The Portable Lie Detector has ‘suspicious spouse’ written all over it.  The handheld device apparently can detect when an individual is lying by utilizing voice tension technology that measures vibration in the voice.  In other words, when someone is calm their voice is smooth and free of ‘vibration’.  In order for it to work correctly you’ll need to determine a baseline by asking 3 questions that you know they aren’t fibbing about.  Oh, and to bring additional credence to the device, a devilish figure with a growing nose indicates when someone is lying.  Works with phones as well. Yours for $80.
