Maybe you have a need for Larsen's unique surreptitious entry alarms and field-tested firefly flasher (tailing device) circuits that can only be seen with night-vision equipment. How about a never-before-published carrier current transmitter detection circuit that will detect all modulation forms,including digital, which is used by the feds?! There's even a leakage detector for phone line taps that outperforms some popular commercial units.

If you're hungry for updated, practical electronic circuits for surveillance and counter-surveillance, this book is a beggar's banquet. There's no speculation here author Tom Larsen makes his living as a counter-surveillance technician, and he has bench-tested every one of his designs. Not only do they actually do what they are supposed to, these ingenious circuits are simple, inexpensive, and fun. You won't find any dry, overly technical explanations in this book. Instead, you'll be treated to colorful descriptions of the real-life applications of scores of circuits and techniques, as well as a basic explanation and schematic detailing clearly and concisely how and why they work. Get the low-down on a never-before-published hook-switch bypass that turns a telephone into a standing microphone while on the hook, using only a resistor, capacitor, and a jumper wire. Learn how to build the bug detector that never hit the market, even though it out performed the top-selling units in the 1980's and early 1990's. Need a never-before published circuit that will stop most spousal phone tapping? It's in here too. So are some simple radio-control circuits for real-world applications that you can construct with readily available parts.

Pepper Shot is a 10% pepper spray rated at 2 million scoville heat units and made with very fine grain that is more effective than the coarser grains of most other pepper sprays. In addition to causing an attacker pain, Pepper Shot swells the mucous membranes, which makes breathing difficult, and swells the veins in the eyes, causing the eyes to close. These effects last 20-30 minutes and cause no permanent damage.
