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.

This is not required in any jurisdiction. Also, whether the officer allows you to see the speed reading has virtually no bearing on your case. Officers can lock on radar readings and leave them on to display to any hapless victim, even though it was not their vehicle that registered the displayed speed.

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.

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.

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.

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.

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.

Depending on the circumstance it is possible for us to sell to trade. Please contact us with your requirements and we will give you quote.

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)

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.

Very, all the units we sell are portable between vehicles, no wiring or drilling involved, you simply plug them into the cigarette lighter socket for power and then mount them on the dashboard with the Velcro supplied, or as we would recommend, on the windscreen with the bracket supplied to give the detector a clear view of the road ahead. As they are portable you can easily put them in the glove box if you are worried about it attracting the attention of a thief when parked.

False alarms can occur, if radar frequencies operate door openers etc. (e.g. at gas stations or in city center situations) in the range of radar detector. These can be reduced by the built-in filter to a large extent. With something exercise wrong and genuine alarms can be differentiated.

Radar and laser technologies are radically different. Radar uses radio waves while laser transmits a beam of invisible infrared light. A radar beam can be 100 feet wide at typical target range. At the same distance, the laser beam will be barely 1.5 feet in diameter. This pinpoint beam width is what makes the laser so difficult to detect. _ There are also significant differences in how the two types of speed-measuring equipment are used by police. Radar can be used from a moving patrol car.
