Do radar detectors really work 100% of the time?
A first important point: Radar jammers are illegal to use in nearly every country, including all of North America, Europe, New Zealand and Australia. In the U.S., it is a **Federal offense** to use a radar jammer in any state. Passive radar jammers DO NOT WORK (that’s why they are still legal). The best radar detectors will detect police radar at up to 10+ miles with very few false alarms. The less you spend on a radar detector, the more unreliable it will be: the less likely it will detect police radar at a sufficient distance and the more likely it will give false alerts. The Bel Vector 940 is one of the least expensive radar detectors sold by Beltronics. Beltronics makes at least 6 radar detectors that are significantly better at radar detection and reduced false alerts, including the 955, 965, 995, RX65, RX75 and the best of ALL radar detectors, the Bel STi Driver. Your problem picking up radar in some towns but not others is probably due to the different radar frequencies used in
