Dektor's PSE, 7010, is a simple plug and play device that is attached to any pc or Mac with its usb plug. The computer can be used the same as before. Training is only 10 days. Training can be done at Dektor, Pennsylvania or at any location worldwide. The company's exclusive "Compu-Learn" can be used worldwide by using the computer, internet and a webcam. Officers have a live instructor for the entire course. There are about 15 imitation "voice lie detectors" sold yet their accuracy has been proven by law enforcement to be only about 50 percent. The PSE only needs to record the vocal answers of test questions by the suspect. But, polygraph needs painfull attached wires. The PSE is never affected by any counter-measures yet polygraph results can be changed by the suspect using drugs, alcohol or physical moves.
