Radar Detector Reviews - Some Useful Information

As the debate on whether radar detectors should be made illegal or not rages on, the fact is that radar detectors are needed, and so, they sell.
Who buys radar detectors?
Although most people would immediately say "people who speed", speeding is not the only reason given for buying a radar detector. People also buy radar detectors to protect themselves against radar gun error. The fact is that radar guns are fallible; this has been proven time and time again. So, by having a detector alerting you to the presence of a radar gun, you become aware of exactly what speed you're really doing. And that can be valuable if the gun misreads.
How does a radar detector work?
Depending upon its design and quality, a radar detector can alert you to devices being aimed at your vehicle to calculate speed. This includes:
Scanning the approved-for-use frequencies (X, K, Ka, and, in Europe, Ku) used by police radar guns. Presence of LIDAR (light detection and ranging) aimed at your license plate, headlights, or fog lamps. Because radar is more frequently used than LIDAR, while most good-quality detectors will alert you to radar signals in time to slow down, only higher-end detectors come with laser detection. Even then, they detect the laser about the same time it detects you-and at that point, slowing down isn't an option.
So why bother with laser detection at all?
On its own, LIDAR detection isn't enough to prevent you from being clocked by laser if you're speeding. However, by having a radar detector that alerts you to laser presence, you become open to a few options. Add on products like anti-laser license plate covers and anti-reflective coating for headlights can be used to reduce the effective range of a laser gun and give you a few extra seconds to slow down. For the serious-minded, there are also laser jamming and laser shifting devices available to block laser signals before they hit your car.
What are the best radar detectors?
Features to look for include advanced radar detection, 360-degree laser protection, auto-scan for eliminating false alarms, and stealth to render your detector invisible to police radar detector detectors.
The Radar Detector Test
Because no two radar detectors are created equal and no two drivers travel the same roads, there are a series of radar detector tests that can be performed to determine which is the right detector for you. This includes testing how well it detects radar and laser; how it performs long range, over hills, and in POP mode; and even how well it disguises itself from radar detector detectors.
While the debate as to the real reason why people buy radar detectors and even whether they should be made illegal continues, at least for today, radar detectors are out there and available for anyone who wants one. From basic models to self-learning ones; the radar detector is getting smarter by the day.

Radar Detectors: What Features Do You Need?

When you've decided to invest in a new radar detector, either for the daily commute or just day-to-day errands, buying a radar detector can seem a bit daunting. There's a whole host of scientific breakthrough specs and technical industry jargon to weed through. Do you need a laser detector or a radar detector? What sort of bandwidth should you look for? Visual or audio alerts? Vg2 shielding mechanisms? Mounted or concealed? More than likely, you are just the average consumer, looking for an effective and reliable radar detecting unit to alert yourself to your own speed, as well as who and where you are being monitored for it. After having done a lot of research on the subject for my own interests, I have broken down all the tech specs and necessary features here, to save you the trouble of both unearthing unnecessary consumer headache, as well as buying the wrong radar detector for your individual travels.
· First off, there are basically three types of radar detectors as far as form is concerned: corded, cordless, and remote mount; each with its own set of pros vs. cons depending on your needs and lifestyle. The corded typically mounts to your windshield, and because of its location offers an aerial less-obstructed detection. Cordless is just that, and offers portable convenience. Lastly, the remote mount variety of radar detectors are mounted permanently to your vehicle, hidden from sight.
· What is the difference in laser vs. radar detection? Though radar detection has long been the chosen method of both drivers and traffic patrol, laser radar detection technology has been adopted by the latter. Police patrol will use laser radar for more accurate detection of closer-range vehicles, and standard radar detection for longer distance detection. Though it is more expensive to find a detection unit with both, it lessens your chance of being ill-prepared on the road. Moreover, you should only buy a laser radar model with 360 degree laser detection; otherwise you will only have the unit detecting in one direction, not from every angle of the vehicle, as is needed.
· City modes? They are basically, the blanket term for precise radar and laser detection in heavy radar frequency zones. The city mode will turn down the range of detection on your unit and perceive less interference or false alerts from external electrical mechanisms as well as other radar detectors in your immediate area. There's much more of this technical buzz in the city...hence the term. So, if you live or drive in more metropolitan areas vs. rural ones, this would be a good choice for you.
· VG2, Spectre, and Invisible shielding technology. The VG2 alert is the basic technology that allows you to know when the police in your vehicle's vicinity are using radar detector detectors or VG2 systems, to discern whether you are using a radar detector or not. Police officials adopted the Spectre system for detecting radar detectors on a broader and more precise playing field, and so the Spectre alert on your new radar detector will let you know when it is in fact being used. This allows you time to shut off your own radar detector, when alerted. The Invisible technology you may want to look for in a higher-end radar detector will be virtually undetectable to the above mentioned police-controlled devices, so you will never have to worry about shutting it down. All of these mechanisms are fairly new and will add expense to your radar detector, but again, it depends on how effective and reliable you need the radar detector to be.
· Bandwidths. Really, the only bandwidth you should have in your radar detector is the X bandwidth. Most frequencies operate on the X, and to incorporate any of the others (K, Ka, Ku), will just be asking for interference from unrelated mechanisms and external electrical stimuli. The result: less focus on what radar detection you should be picking up, such as police radar.
These are the basic necessary components in any reliable and accurate radar detector. You will find many more features available in these systems, but they are cosmetic in relation to the significant ones listed here. Start with these terms/tips for form and function, and then move on to whether you'd like luxury components such as voice alerts and enhanced LED displays.

Radar Guns: How Do They Work?

We've all heard of the evolving technologies that police patrol use to determine a vehicle's speed on highways, secondary roads, and downtown congested byways... Basically, anywhere you drive, you are subject to the laws' supervision and enforcement of speed limits in the name of common safety. But how does patrol effectively and accurately determine the speed of your car? Radar guns... The point and shoot technology of these trusty devices becomes more and more foolproof every day; so that if you're speeding in a monitored zone, you will be caught. In this article, we'll discuss what sort of mechanisms make the radar guns' results practically indisputable in a court of law, and what steps you can take to avoid being whacked with a hefty fine and/or arbitration.
The basics of radar gun technology is this: radio waves are transmitted from the radar gun to the speeding object, and then reflected back to the radar gun on a different frequency (in mph). Most radar guns automatically go through this process a number of times for one point and click...to ensure precision and accuracy. Beyond this definition, there are also two types of speed gun detection on the roads: radar and laser gun technology. Whereas radar guns pick up the converted frequency of your moving speed, laser guns use the time the light pulsing beams take to get back to its source, to evaluate your speed. So which one is more effective, and what sort of patrol uses which? Radar gun accuracy is dependent on the source being in transit, so you will find that state highway police use radar. And the converse is true: laser guns are used in the city, as the laser's accuracy is dependent upon a non-moving source. Laser guns are able to pinpoint single vehicles, whereas a radar gun has more room for error in hitting the vehicle in front or behind you. In short, laser guns are better for shorter range detection, and radar guns are better for wider range detection.
Typically, a radar gun's accuracy is +/-1 mph at +/-2 degrees angle behind or in front of the moving object. The more obtuse the angle, the less accurate the reading becomes. So, if you are being radared from an officer from the side of the road as you pass him/her, your chances for disputing the ticket due to improper technique are very good. That's why when you pass an officer, he/she will get behind you for awhile before flashing the blues, to get a better angle in relation to your vehicle, and to therefore better their chances of an accurate speeding readout. Most radar guns have an approximate range of 6mph to 200mph...anything below or above this, the device cannot handle. Luckily for patrol, most of our vehicles will stay safely within this range. Police also sometimes have a continuous mode radar or laser gun, which will automatically take readings of moving targets without the patrol having to point and click every time.
Of course, as is true of most technology, there is still a window of opportunity for error. In this case, inaccuracy might arise mostly due to improper use. If you are the patrol, it is imperative to turn down the sensitivity of the radar in certain congested zones to avoid interference; make sure not to angle the radar gun unless in a stationary mode, and also be aware of general external interference, such as surrounding topography and other radar-transmitted devices. If you are the target of one of these devices, you should be aware of these influences, as a possible misdiagnosis of your speed.
So if you are a civilian, how can you combat radar and laser gun detection? Most would answer radar detectors. Radar detectors will pick up most radar guns' frequencies. In all cases, if you decide to invest in a radar detector, do not skimp or opt for a lesser version to save a couple bucks. The higher end radar detectors will give you better range which will alert you sooner to a patrol's presence and give you more time to slow down. They also have features like 360 range detection, so you will be able to pick up radar presence from every angle. Moreover, more and more patrol are using laser detection guns to register traffic speed, and as the light beam transmitted is only 1.5 feet wide, it is much harder for your device to pick up it's use; so if you can afford to have a laser radar detector, I would strongly recommend it.

Radar, Laser, Police Detectors - What Is It, What To Look For, And How To Buy Quality Radar Detector

What is it?

To first of all answer your question, radar, laser, and other police frequency detectors are not illegal outside of Virginia and the District of Columbia (D.C.) Radar detectors are only illegal in commercial vehicles or passenger transport vehicles. Basically if you drive anything bigger than a standard pickup truck, you should not use a radar or laser detector in your vehicle.
You could probably imagine why anyone would want a radar detector. It's primarily for all of you speeders out there who would like to avoid a fat traffic ticket. Even if you're not an excessive speeder, you may even find laser or radar detectors to be useful. There are some areas where police or highway patrol officers are more tolerant of minor speeding, yet there are also those areas where they seem to pull over anyone going 1 mile per hour over the speed limit. If you drive in Los Angeles, 10 to even about 20 miles above the posted speed limit signs may be tolerated as long as it's with the flow of traffic, however, going 80 in a 65 MPH zone in the middle of Utah may not be so tolerated by the highway patrol. Whether or not you're an intentional speeder or a faster-than-most type of driver, a radar or laser detector could save you hundreds if not thousands of dollars.
Another much less-popular usage for a radar detector is for the detection of emergency vehicles. This helps a lot if you're listening to loud music in your car and can't hear audible sirens outside. Some Cobra radar detectors are capable of detecting emergency vehicles approaching your location so that you may safely move aside for them.
Let's go over some of the most important features that you'll want to look for in an effective radar detector.
Radar Detectors Features:
First, figure out how much you want to spend. You're more likely to find high quality brands and products within the $120 to $200 price range. Cobra radar detectors are some of the best quality ones you'll find in this price range, as well as Beltronics detectors in the lower end of the price range.
Next, find the most comprehensive detection available in each of the products. Simple radar detectors will not detect laser or the most high-tech police speed readers out there. Police speed readers have progressed as fast, if not faster than the commercial radar detectors. Laser detection was developed after radar for much more accurate and longer range detection; and they have also implement KU-band hard-to-detect radar speed gun. In addition, the police have also used VG-2 radar detector-detectors to find suspected speeders.
Scary huh? Well don't worry because Cobra digital radar and laser detectors have you covered. Cobra detectors are capable of reading simultaneous signals with multiple channel detectors. This means that if there are more than one cop out there, some Cobra laser/radar detectors could track up to 12 signals. It could detect radar, laser, and even KU-band signals with Spectre or VG-2 detector-detector coverage. Some Cobra radar detectors also have voice alert feature that announces the detection of nearby signals. Most units, even Beltronics radar detectors, also feature a city/highway mode switch that reduces the amount of false signals that could be detected or triggered from other wireless radio transmissions such as wireless internet, handheld devices, etc.
There are also bells-and-whistles features in some of the more expensive models. For instance, the higher-end cobra radar detectors feature battery voltage meter and an 8-point compass that indicates where the detected signal is coming from. My best advice to you is to find a radar detector that functions effectively with all detection and "stealth" coverage with as little bells-and-whistles as possible to reduce the price. Don't just settle for the cheapest radar detector because they're likely to fail you and more likely to waste your money... not to mention a hefty traffic ticket! I suggest looking for Cobra radar detectors or BEL radar detectors as they seem to have more effective features than most generic brands.

The Reason Why Reading Radar Detector Reviews is Important If You Consider Buying One

Since the very first radar gun and the very first radar detector have been invented, an arms race of sorts has began. Wielders of the radar gun, members of the police force, attempt to catch drivers who drive over the speed limit. On the other side, the average Joe, owner of a radar detector, does not wish to be caught speeding nor does he wish to be falsely blamed for speeding because of a faulty gun.
This arms race causes manufacturers of radar guns to find way of overcoming the ability of radar detectors' ability to detect them, and vice versa: manufacturers of radar detectors find ways of outsmarting radar guns - and even jamming their signal altogether.
Consequently, new models are occasionally released that are specifically aimed to deal with the new features of the 'nemesis' (for lack of a better word). Just like an old radar gun is almost certainly going to be useless against modern radar detectors, an old radar detector will not be effective against modern police guns.
The 'arms race' from a technical perspective
Radar detectors detect EM emissions from radar guns and trigger an alarm to the driver that a radar detector is used in the area. In order to outsmart radar detectors, radar guns change frequencies to those that radar guns are insensitive to and so, are effectively blind to them. However, once detector manufacturers figure this out, they enable their devices to be sensitive to these frequencies as well.
Furthermore, some devices passively absorb the radar signal, and consequently, render the car invisible to the radar gun. Note that this can look suspicious to a police officer with a radar gun.

New radar guns use laser light (called LIDAR) instead of EM emissions. Older radar detectors would be completely ineffective against this type of radar gun. However, radar detector manufacturers have a way to circumvent that as well.
In addition, technology has been improving in other ways. By incorporating GPS technology into radar detectors (as some model do, for example, the Escort Passport 9500ci) radar detectors do not always have to detect the presence of radar guns - all they need to do is connect to a database of people who have reported the presence of radar guns in certain locations, and simply drive slowly in these regions. This is an impressive feat, though personally I believe the other side is already working on a way of circumventing that as well - perhaps by creating numerous false alerts in order to make this database useless? We shall have to wait and see.
From an academic perspective, it is an interesting topic to follow. However, in practice, if you want to use a radar detector, you must be sure it can deal with modern radar guns, otherwise, you may be setting yourself up for a very unpleasant surprise as you might find yourself overconfident because of your radar detector device.
In conclusion: only by reading up-to-date reviews of radar detectors you can be certain that you pick the best radar detector for your needs, and that it will be effective in this day and age. One last point: it goes without saying that before buying a radar detector, you need to make sure that using and owning a radar detector is legal in your state and country.

Radar Level Gauge FAQ

The technology surrounding the radar level gauge has vastly improved in the last ten years, mainly due to the innovative leaders continuously improving radar technology. They have made non-contact radar transmitters a level measurement technique that is to easy to use and understand, offering a real usable alternative to differential pressure transmitters and displacers. Let's look at some questions that you might have about radar level gauges.
What are the Main Industries Radar Transmitters are used in?
The radar level gauge is very industrially friendly, as it can be used for level measurement of both solids and liquids in all sort of environments - I mean just look at the examples of where you can use it below.
Where Can I Use a Radar Level Gauge?
As mentioned above, you can use these non contact radar transmitters for level measurement in tanks and vessels for liquids and solids. In fact, you can use them for almost any liquid and solids in processing or storage environment because this technology is so versatile. This versatility means that the radar measurement is not affected by changes in the process like dust, temperature, gas vapors or pressure. As the radar gauges are non contact and versatile, you can rely on their performance.
The most modern and innovative radar measurement units have built in linearization software, which calculates the level versus shape and provides a volume output on the following example types of application:
Level measurement in processes that use vessels, mixers, blenders, reactors and scrubbers. Liquid applications where hygiene is of utmost importance like distillation and purified water. Radar is even suitable for water applications with water sprays. High temperature molten applications like metals, coke products and minerals can be monitered effectively with radar transmitters. Storage vessel tank gauging. Measuring the interfaces on liquids in difficult applications
How does Radar Transmitter Measurement Work?
Millions of short microwave pulses are generated every second by the electronics and transmitted out of the instrument using either a rod or horn antenna system. The pulses are directed down to the liquid or solid surface by the antenna system and are reflected back to the instrument. It is known that the pulses travel at the speed of light, which means that measuring the time taken between transmission and receipt of a pulse can give the distance that the pulse has travelled, and hence the distance to the product surface. This process is a continuous measurement.
Why Should I use Radar Level Measurement?
Because radar transmitters are so versatile, they can fit into your process by being top mounted, side mounted and even put on the outside, as the radar works through glass or plastic. Using a radar level gauge also has the following advantages:
You can maximise your vessel capacity with very small blocking distances You can install or change radar transmitters without the need to empty your tank , so the process will not be interrupted. Once again the process does not need to be interrupted when commissioning, which can be accurately done on or off line, without the need to change the level The radar level gauge has no moving parts, which means there will be no drift or recalibration required. Radar level gauges handle agitators and obstructions easily using specialized software
How Reliable is Radar?
The better brands have SIL 2 (IEC 61508/615011) conformance on their radar level gauges, which is a special evaluation required for high integrity applications. To get this conformance the radar gauges have been tested for reliability and performance for use on hazardous processes or products. These types of radar transmitters can be reliably used for level switching (high and low), interface measurement, continuous level measurement and tank gauging.
