It's one thing to be ignorant. We all are at one point. But, we do our own homework and learn. Copying other people's homework never leads to the A+ answer.
It's a, "Which end of the soldering iron should I hold?" question. If you don't know, better find something else to do.
The Editor-in-Chief of PI Magazine, kindly responded with the following cogent reply...
A. There really is no such thing as a cheap do-it-yourself debugging product. Even the most basic TSCM / debugging inspect requires you search for RF (radio frequency) signals, hidden video cameras that are either wired or wireless, on or off, hidden audio records, telephone instrument and phone line inspection, as well as searching for GPS trackers that can be battery operated or hardwired.
Each of the categories listed above require specialized equipment unique to the item(s) being searched. Even if you were to acquire a cheap RF detector, you wouldn’t know what type of signal you’re picking up or the source... Just because you own a piece of equipment doesn’t mean you’ll know how to use it.
By the way, the FTC has been known to criminally charge private individuals and PIs for “theft by deception” for conducting bugsweeps without the proper equipment and training.
UPDATE: A Blue Blazer Regular writes in with his two cents... "Doing it yourself is like do-it-yourself brain surgery."
