Safe Line Telephone Analyzer & Tap Detector

The SL-100 offers six levels of protection against eavesdropping attempts, more than any other device of its kind. Whether you are on or off the phone, line voltages are constantly monitored and displayed, alerting you to almost any type of bugging device on your line. In addition, taps are neutralized or deactivated for the highest level of privacy protection. Even voice activated systems are rendered useless by the SL-100 Anti-VOX system.
