Bug Detectors and Sweeps

I've always been interested in electronics. I found my first bug at 15. Since then I obtained my amateur (ham) radio license, KC2PYP, and even today, I have an amateur radio station in my home.

Formally trained in TSCM (technical surveillance counter measures) I've been doing wiretap and bug sweeps in the New York-metro area for a few years. My clients have ranged from ordinary people to celebrities, politicians, police, lawyers, accountants, hedge fund managers, socialites, and a famous auction house.

One thing that struck me a few years ago is that almost all bugs are found with a visual sweep. At least this is true where there is a fairly low threat. Of course, if the government taps your phone or bugs your office, it's going to be thoroughly professional and top notch. Even I probably couldn't find it, nor would I want to.

Most of my cases involves so-called infidelity cases. Jealous or suspicious spouses, boyfriends, girlfriends, tap a phone, or place some bugs where they want to eavesdrop. Some of them do it themselves, others hire unethical P.I.s to do it.

In almost all these cases, the wiretap or bug can be found with a visual inspection, if one knows what to look for. With this realization, I wrote a manual so that people could learn to do it themselves. While it was aimed at my typical client, other P.I.s, who don't know anything about TSCM, could benefit too.

"Locating Wiretaps and Bugs...Without any Special Equipment" is a how-to manual for the do-it-yourselfer. It has about 36 full-color photos and describes in detail what to look for. I'm confident that almost anyone could find most wiretaps and bugs by following the steps in this manual.

Years of experience and knowledge have gone into this manual. In handy PDF form for downloading, it's only $29.95. TSCM work is expensive, but this little instruction booklet could save you hundreds or even thousands of dollars. To order, just click here.

Now, if you suspect the authorities are tapping your phone or have bugged your office, you need a lawyer, not a manual.
