Signals reflected off buildings, obscured by underground garages, rapidly accellerating as they get on the freeway, etc. are all confusing. Following a vehicle without being detected takes practice. The beeper just makes it possible to do with one tail car instead of two or three. With an aircraft, one of these guys can identify the location of a vehicle within 25 or 50 miles. Have fun! Places to buy: Wynn Engineering / 4327 Aspenglen Dr. / Houston TX 77084 sells a bumper beeper set that "When installed on your car, you can track the distance and direction of the car from up to 2 miles away. Beeper and special receiver (Model BB 1101) $600 for the set." Law Enforcement Associates / 88 Holmes St./ Belleville NJ 07109 sells a better system (made by TRACER) called the 1012 Vehicle Follower System. It's better because the beeper beeps instead of emitting a continuous tone (saves on batteries!) and it gives a more specific readout of the direction of the target. Expect to pay over $1000. Write for a current catalog. And by the way, US Citizens have no reasonable expectation of privacy regarding movements tracked in public, said the Supreme Court in 1983: US v. Knotts, 103 S. Ct. 1081 (1983). Larry
