Advanced Transmitter Detector

The TD-53 can be used to detect, verify and locate hidden transmitters in your home, office or car.

Use the TD-53 to perform a professional RF sweep of your premises, including your telephone system. Similar in operation to a Geiger counter, the sensitive antenna system can be used to probe all areas of a room. As the antenna approaches the hidden transmitter, the audible tone clicks faster and faster while the ten step solid-state meter indicates the signal strength.

At this point, switch modes from Detect to Verify to differentiate a bug from a regular radio or TV transmission. If a bugging device is present, a continuous squealing tone is generated by the TD-53. By sweeping the probe, this tone can lead you directly to the bug. The switch selectable SENSITIVITY level improves detection capabilities of the unit in high signal strength areas. For private (non-alerting) listening, an earphone jack is provided.

Included with the TD-53 is the P-01 wideband active probe which covers 5 MHz to 2,500 MHz. The P-01 can be positioned up to 25 feet away from the TD-53 by using an extension cable. For example, the probe could be discreetly placed in a target room while the TD-53 is monitored in another room. The unit measures 5.8" x 3.4" x 2" (with cover closed) and weights 9 oz. It is powered by one 9 volt alkaline battery (included). Also included is an illustrated instruction manual.
