The TD-17 is designed to locate the most common type of electronic bug - the miniaturized radio transmitter.
Audio bugs can be planted by almost anyone, almost anywhere, including boardrooms and offices for purposes of corporate espionage. Find hidden RF transmitters (bugs) planted in your home, office, car or attached to your telephone line. In use, the TD-17 warns you of the presence of a nearby RF transmitter, within the frequency range of 1 MHz to 1,000 MHz by the RF ALERT LED. The flashing RANGE LED and audio tone give an indication of the distance to the bug. The SENSITIVITY control, along with the two LEDs, helps you quickly zero in on hidden bugs. (After a little training, a five year old child was able to locate a well-hidden transmitter in a 1,600 sq. ft. building in less than 5 minutes.) The TD-17, which weighs 7 oz., is furnished in a high-impact case that measures 5.3" x 3.3" x 1.5". The antenna can be extended 33" and telescopes into the case for convenient storage. The unit comes complete with battery, antenna and instruction manual.
