Light beams, especially lasers, provide an excellent method for carrying audio intelligence and are not detectable by RF (Radio Frequency) detectors. The P-02 is a special probe which allows you to search for sources of infrared (IR) transmissions. In the case of amplitude modulated or pulse frequency modulated sources, you can actually listen and determine if the IR beam is carrying voice or other intelligence.

The probe is used in conjuction with the TD-53 Advanced Transmitter Detector. Both are included in the Countermeasures Sets CMS-11 and CMS-15.
