They're legal, but don't count on one to warn you in time to avoid a ticket. An officer who wants to catch speeders won't turn on his radar unit until he or she is ready to verify the speed of the violator. Some agencies in Florida and elsewhere employ trained pilots who clock vehicles from the air using a stopwatch, not radar. The only way to be sure of avoiding a traffic citation is to observe the speed limit. See similar questions...

In order to catch a driver speeding, there are various devices used by law enforcement, which emit various types of radio signals that enable them to calculate your speed. Radar/laser detectors are nifty bits of equipment that alert you (audibly or visually) to the presence of these devices by picking up the various signals emitted. See similar questions...

In a nutshell: Modern radar detectors are superhetrodyne receivers, similar to a scanner. First, they use a microwave horn antenna to receive the radar signal. The radar signal is generally passed on to a first mixer stage, where it is mixed with a first local oscillator to produce an IF. The IF is generally passed on to one or two more mixer and IF stages depending on the design. See similar questions...

A radar signal is conical in shape, much like a torch beam. At 200 yards, the normal range of a radar gun, the signal is as wide as a dual carriageway. Most of the signal therefore goes past the target and on up the road reflecting off trees, houses etc, eventually becoming "radar scatter". Snoopers are extremely sensitive radio receivers tuned to these frequencies and can detect very small particles of "radar scatter" at up to 2 miles in some cases. See similar questions...

Different models of radar-detectors can operate in different frequency ranges. Models, that operate in laser range, can have a sensor to receive a signal from behind. There are some model constructions that have antenna block outside the car salon, and control panel and - inside. Hidden models of the radar-detectors are interesting too, for example that are hidden in back-view mirror. See similar questions...

There are a few systems which do not work on radar or laser and therefore radar detectors cannot detect. They don’t detect VASCAR (being followed and videoed by an unmarked police car) and the SPECS SVDD and Truvelo systems. The GPS detectors alert you to these systems when they are in fixed locations.

Radar detectors can be fastened with small suction cups to the windshield, alternatively offer themselves a hook-and-loop fastener on the instrument panel or the assembly with a clip at the sun visor. The necessary assembly material is completely provided. See similar questions...

U.S. non-commercial drivers should not be concerned at all unless you drive in Virginia or Washington DC. If you do drive in either of those places, are a commercial driver, or drive in Canada, please note that while all of our current detector models are immune to the VG-2 radar detector detector (RDD), our radar detectors can be detected by a newer RDD named Spectre.

A The Snooper S3R/S4R/S6R & Evolution-R combine radar/laser and GPS unit. The RoadPilot Pro & Micro Roadpilot usually comes with the LaserPilot and can be upgraded to Radar. See similar questions...

Additional arrangements to have round view in radar-detectors are not necessary, because such radar-detectors receive signals from all directions, however the sensitiveness from behind is low. Keep in mind that control from behind is held from small distances and then the information about violator is send to the next police station. See similar questions...

In principle radar detectors are very mobile and can be used permanently in other vehicles (e.g. rented cars) . Exception: Fixed installaled devices in the engine compartment (e.g. BEL 590 R euro) See similar questions...

Radar helps you see what's around you. An antenna mounted high above your boat (often on the mast of a sailing vessel) sends radar waves down towards the ground, hoping to pick up reflections of land or other boats below. It's not foolproof - it can often pick up images of waves instead of real objects - but it definitely helps you see what's around you, especially in conditions of poor visibility.

Yes, they really work too. The list consensus is that Valentine Research V1 is the only way to fly low and fast. Probably the most expensive detector out there, it consistently comes in at the top of various comparison tests. Valentine One is about two times more sensitive than the second best--and about two or three times the cost. It has unique features that provide important information. It is overwhelmingly preferred by prezzes. Bel 945iM is a gimmick. See similar questions...

Some models that we carry, such as the Bel 995, and the Bel RX65, will also detect the Ku band. The following is the Ku band range: See similar questions...
