World's Best PROFESSIONAL
COUNTER-SURVEILLANCE DETECTOR
CSD-21 Professional Counter-Surveillance Detector

THE ULTIMATE IN "BUG" DETECTION EQUIPMENT!

If you require GUARANTEED PROTECTION against electronic telephone monitoring devices and also require COMPLETE CONFIDENTIAL PRIVACY in certain rooms and areas, we highly recommend the Super-Sensitive
COMBINATION DETECTOR CSD-21.

"DEBUGS" ROOMS AND TELEPHONES

The CSD-21 will provide the absolute maximum degree of protection possible today against all types of telephone taps and room bugs. Specifically detailed, step by step instructions assure easy operation and absolutely no technical knowledge is required.

Any improper readings in either mode will immediately be brought to your attention via sequential flashing LEDs, conspicuous meter indications, or a combination of both. Completely silent operation allows entirely covert "sweeps" making it possible to introduce false information to reveal the identity of the eavesdropper. Convenient output jack also allows for input into any standard cassette recorder and proves invaluable for the recording of any unidentified sounds detected, including all intercepted audio.

EXTREME SENSITIVITY!

Universally acknowledged as the finest single piece of professional detection equipment manufactured today, the world famous CSD-21 features an ultra High-Gain Amplifier stage which makes possible the extreme sensitivity and superior detection range.

And, the presence of any type of "bug" is immediately indicated via LED sequencing and meter indications. This electronic marvel actually picks up many Eavesdropping Transmitters at ranges up to 25 ft! The CSD- 21 quickly "homes-in" on any eavesdropping device and immediately pinpoints its location.

DETECTS THE LATEST "SUPER BUGS"

Exclusive GSS proprietary circuitry contained in the CSD-21 detects even the very latest sophisticated Eavesdropping Devices including "Frequency Hoppers" and "Burst Bugs" which are specifically designed to deteat detection by shifting frequencies, storing information and then releasing it in brief bursts. Also features the unique Infinity Tap Detector/Locator and a "LISTEN-IN" Mode which allows you to monitor all audio.
