When the energy encounters semi-conductor junctions (diodes, transistors, circuit board connections, etc.), a harmonic signal returns to the receiver. The receiver measures the strength of the harmonic signal and distinguishes between 2nd or 3rd harmonics. When a stronger 2nd harmonic is represented on the display in red, it indicates an electronic junction has been detected. In this way, a hand-held ORION is used to sweep walls, objects, containers, furniture, and most types of surfaces to look for hidden electronics, regardless of whether the electronic device is turned on.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ORION\u2122 Non-Linear Junction Detector (NLJD) detects the presence of electronics, regardless of whether they are radiating, hard wired, or even turned off.
