The ongoing battle between speeding drivers and traffic law enforcement has introduced a new contender: the radar scrambler. With a price tag of less than $100, Americans can easily acquire this device. For $199.95, a more advanced model is available, capable of jamming both police liDAR and older RF radars. These scramblers outperform conventional radar detectors by emitting signals that perplex police radar systems, rendering it impossible to precisely determine a driver's speed.

The use of radar detectors is prohibited in the UK, along with several other European countries, and some US states. According to Mike Churchman, the founder of Rocky Mountain Radar in Littleton, Colo., scramblers are not subject to the same regulations as radar detectors. This is because scramblers do not detect radar signals; instead, they utilize a high-gain antenna to reflect incoming signals back to the radar gun, while simultaneously emitting another radio signal to confuse the receiver.

In the early years of the Iraq war, the U.S. military developed a technology so secret that soldiers would refuse to acknowledge its existence, and reporters mentioning the gear were promptly escorted out of the country. That equipment – a radio-frequency jammer – was upgraded several times, and eventually robbed the Iraq insurgency of its most potent weapon, the remote-controlled bomb. But the dark veil surrounding the signal jammer remained largely intact, even after the Pentagon bought more than 50,000 units at a cost of over $17 billion.
