Lie Detector

Handy Truster is a handheld, portable LIE DETECTOR. More accurately it is a voice stress analyzer. When people lie the blood pressure changes in their vocal cords. This change is not audible to us but the Handy Truster is designed to pick up on these subtleties. The Handy Truster is built upon Israeli chip technology and boasts an 84 percent accuracy rate. The microphone on the side of the unit picks up the subject's voice. Spend about 10-15 seconds calibrating the unit with truthful statements from the subject. Then go ahead and ask 'yes or no' questions. The digital apple on the screen will be your gauge. When the person lies or gets excited bites will be taken out of the apple. Handy Truster can also be used in 'cell phone mode' and connected to most models of cell phones.
