If you are involved in surveillance on other people, chances are that there are other people involved in surveillance on you. In order to detect when others may be listening in on you, it is a good idea to keep one or two different types of spy bug detectors. Because there are plenty of different bugs out there, and because they make use of a variety of different technologies, it is important to have at least two different types of spy bug detectors in order to sweep for multiple types of listening devices.
Because the most popular listening devices are RF (radio frequency) bugs, it is important to make use of RF spy bug detectors. Choose a sensitive model with good bandwidth and circuitry. It is good to have one that can pick up a wide range of frequencies so that you are not missing a bug, and then feel confident that it has been removed. Of course, if you are in an area where there is a great deal of ambient RF energy, there may be too much interference. The good news, though, is that with most detectors of this type it is possible to experiment and then familiarize yourself with the unit so that you can still use it even in high RF areas.
Electronic eavesdropping can also be detected with spy bug detectors that not only find electronic signals in a room or on a person you are speaking with, but also pinpoints them It is possible for you to get a detector with a LED display that shows you exactly where the bug is located. This can help you to either find and disable the bug, or let you know where it is so that you can
