A Guide To Discount Radar Detector

Radar detectors are extremely effective for warning a driver that he is approaching a speed detection device that uses a radar system. Some of these radar detectors can be extremely expensive but finding a discount radar detector is relatively simple if you know where to look. Here is a quick guide to where to look for discount radar detectors.
Online sales
If you perform a simple search for discount radar detectors, you will see that there are literally hundreds, of sites that proclaim they have the best discount radar prices on the internet. This is a good place to start as you can compare the features and the prices of the various types of radar detectors available. You do need to be aware of potential sales taxes that may be added to the final price. This depends, not only where you live, but also where the discount radar detector is being shipped from. Shipping costs also need to be taken into account. Many of the discount radar detector sellers online are actually wholesalers and are able to offer lower prices because they have bought their stock in bulk.
Retail outlets
There are a number of electronics stores that sell discount radar detectors. The trick is to look for flyers or advertisements in your local Sunday newspaper. There are nearly always coupons that you can use towards the purchase of any electronic product. This method enables you to create your own discount radar detector price. The benefit of buying radar detectors this way is that you can actually see the units before you buy them. Another means of tracking down discount radar detectors in retail outlets is to watch out for their special offer periods or sales. These often happen when a new model is being introduced and they need to clear their old stock. You are sure to find discount radar detectors that suit your budget.
Used radar detectors
As with any technology, speed detectors are constantly evolving and being updated. This leads to a number of radar detectors being sold as second-hand. You can pick up a discount radar detector that works perfectly, but is not the latest model. It is important to check that the unit still works before you buy it, but this can be a great method of obtaining discount radar detectors. It is certainly worth checking local advertisements to see if there are any discount radar detectors for sale. Garage or yard sales and rummage sales can be a surprisingly good source of discount radar detectors. You never know where you might pick up a bargain!
Online auctions
There are a growing number of online auction sites, but eBay is by far the most well known. This is a great place to search for discount radar detectors. It is important for you to check the recommended retail price of any product that you are interested in to ensure that you do really buy a discount radar detector. You also need to take into account the delivery charges as these can sometimes turn a discount radar detector price into a more costly one than those found on retailer's websites.

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.

Refurbished Radar Detectors

Refurbished radar detectors are radar detectors that consumers return to the manufacturers or retail stores during return period. They may be used or unused. The company reconditions them to sell as refurbished items. A specialty of refurbished radar detectors is that their prices are remarkably low and they provide the same benefit that a new radar detector offers.
Radar detectors generally reach factories or manufacturers for refurbishment due to various reasons like customer returns and cancellations, shipping damage, and cosmetic blemishes. Usually, radar detectors manufactured by leading companies come attached with warranty or return policy. Some customers return the products during this period, and the manufacturers, after making necessary changes, repack them as refurbished radar detectors. Shipping damage generally occurs due to mishandling of the equipment during packaging process, and cosmetic damages are in the form of scratch or dent.
Today, most of the companies as well as retail outlets have a section exclusively for refurbished radar detectors. The refurbishing process includes detailed inspection of the equipment, cleaning-up processes, and performance testing. In some instances, during the refurbishing process, the radar detectors are reassembled and tested electronically.
A refurbished radar detector offers the best value for your money. Usually, the cost of radar detectors with the most sophisticated technology is very high. By buying a refurbished radar detector, the customer acquires a most modern radar detector at very low rates, which is sometimes half the price of a new radar detector. For instance, if the price of a new radar detector is $300, the price of a refurbished one could be as low as $150 and sometimes even less. The price of refurbished radar detectors vary according to model and types.
It is always advisable to buy refurbished radar detectors from the original manufacturers or companies. It is also vital to check the warranty period of the refurbished radar detectors. Refurbished radar detectors can be purchased from authorized dealers, retail stores, and online stores.

Used Radar Detector Prices

Used radar detectors prices are reasonable and negotiable. It is quite difficult for an ordinary buyer to purchase a new, high-end model radar detector, due to its high price. But, a used radar detector is a previously owned detector which can be acquired at an exceptionally low price. The prime benefit of used radar detector is that in most cases, the consumers get a new model, sometimes along with warranty, at cheap rates. Used radar detectors are generally categorized by the price range - economy, mid-range, and expensive. Other factors that determine the pricing of used radar detectors are condition of the equipment, the manufacturers, place of purchase, the model, the type, and the year when it was first purchased.
Whistler XTR-590G Radar Detector
The prices of used radar detectors generally start from $50 or sometimes even less. For some of the latest models from top brands such as Beltronics and Whistler, including Whistler Cruisader Motorcycle Laser Radar Detector and Beltronics Vector 990 International Frequencies Radar Laser Detector, the prices range between $220 and $260. In the case of used radar detectors with voice alert and cordless radar detector, the price ranges from $90 to $120. The price of used Band High Performance Digital Radar/Laser Detector from Cobra is about $110.
Used radar detectors can be purchased from owners, dealers, or from superstores. It is always wise to buy used radar detectors directly from the owners, as the prices will be negotiable as well as reasonable. In the case of superstores, used radar detector prices are not negotiable, though they are usually sold for a reasonable, predetermined price. The best deal on used radar detectors can be found on the web, where majority of the dealers have sites. They provide the latest information and pictures of used radar detectors. Amazon.com, Buy.com, and eBay.coms, are among the prominent websites where you can search for used radar detectors.

Valentine One Radar Detector - It's The Arrows

Situational awareness is the most crucial need of any driver on the road today and having a good radar detector that has superior range is also important. One radar detector that assists drivers in both these areas is the V1.
Their directional arrows are exclusive to the Valentine One. These arrows notify the user from what direction the radar source is coming from. The arrows are extremely helpful for identifying a radar threat from a false alarm. The arrows point in four simple directions- front, rear, left, and right. If a radar source is ahead of the driver, the forward facing arrow will illuminate, as the driver approaches and passes the radar source, the arrows will indicate the radar source is located to the left or right of the vehicle. After the vehicle passes, the arrows will indicate that the radar source is behind. This simple idea has overwhelmed the industry and has kept the V1 ahead of the pack.
Paired with the arrows is another patented design by Valentine Research-dual radar antenna receivers. This dual-antenna design allows the radar detector to be equally as sensitive to rear located radar sources as it is to radar sources ahead of the vehicle. Other detectors have only one radar antenna. This is good for front located radar detection, but less than satisfactory for radar sources located anywhere else. Having only one forward facing antenna forces the detector to rely only on radar signals bouncing off of other objects and finally into the antenna. Valentine Research has eliminated this methodology of rear source detection with its rear facing antenna. No matter where the radar source is, the V1 will alert to it, before all other radar detectors.
The Radar and Laser sensitivity levels are also worlds ahead of the competition. The V1 will be the first to alert in almost all situations. In independent tests, the V1 has outperformed all other brands of radar detectors. The detection range is superb and the sensitivity is extremely responsive. In tests against extremely short bursts of radar signal, also known as quick trigger, the V1 has never missed a beat. While most other radar detectors would remain silent, the V1 will alert to the short burst and allow adequate time for the driver to adjust their speed. The V1 is also great at detecting cases of instant on, where the radar user will keep the radar unit off until the car is visible, then instantly turn the radar on to get a speed reading. This method is used to defeat most radar detectors, but the V1 will always prevail.
Another great feature is the upgradable hardware. As new technology is developed, the V1 will always be prepared. Instead of buying a new detector every few years as new technology arises, simply send the unit in for a free tune-up and hardware upgrade. This saves vast amounts of money compared to buying a new radar detector.
The suction cup windshield mount for the V1 arguably the best mount in the industry. While most mounts will fall off in extreme heat or cold, most users can confirm that their mount has been in the same position for years, and has never lost suction to the windshield. This is extremely valuable, because nobody wants their expensive unit to be held up by a bad mount.
The Valentine One is one of the top radar detectors in the industry with their hardware and software upgrades, arrows, and great sensitivity, purchasing a V1 will not be regretted.

Where to Find Cheap Radar Detectors

Since radar detectors are generally expensive, some people prefer to buy cheap radar detectors. For manufacturers and dealers, cheap radar detectors are a promotional technique used to increase their sales. Customers are satisfied with cheap radar detectors because they provide the same quality and service as that of expensive, high-end models at a much lower price.
The price of cheap radar detectors generally depends on the category, installation, and type. Cordless radar detectors, traditional corded units, and remote mounted units are some of the types available. There are several sources to get cheap radar detectors. One of the best sources to find cheap radar detectors is stores offering products at discount rates. Many radar detector dealers, both stores and online, sell high quality radar detectors at discounts. These stores get products from the radar detector manufacturers at cheap prices. Generally, their aim is to increase sales by cutting on profit margins. Another popular option for cheap radar detectors is buying used ones. Classified ads, estate sales, and garage sales are among the sources where customers can get great deals on used radar detectors. Some stores even have a section exclusively for used radar detectors. Cheap radar detectors can also be bought from outlets or companies, who want to replace their existing models with the latest ones.
A cheap radar detector is not necessarily a high quality product. Hence, before purchasing a cheap radar detector, it is necessary to make a thorough research on cheap radar detectors available in the market. Quality, sensitivity and memory, display and volume, and brand name and model must be taken into consideration. It is always wise to buy cheap radar detectors sold by top brands like Beltronics, Cobra, and Whistler, as they offer some kind of warranty. Sometimes, manufacturers offer free shipping for cheap radar detectors on making a minimum purchase.

What Is Radar And How Does It Affect Your Driving?

We have all heard of the term 'radar' but we rarely ask ourselves what radar really means? What are its uses? And what is the purpose of it?
Radar is a short form for 'radio detection and ranging'. It is a remote detection process which is used to trace and identify objects.
Radar can determine the distance, speed, direction of motion and shape of an object. The radar can identify objects even if it is out of sight. It can also work in all kinds of weather conditions which made this an essential tool for many industries.
This device is used in navigation in the sea and air, helps in detecting military forces and also helps improve traffic safety. Radar has also become a very important tool for every policeman because they can easily catch a speeding motorist by only using radar detector.
But how do these radar detectors work?
In order to work the radar system is composed of four very important components. These are the transmitter, the antenna, the receiver, and the display.
o The transmitter produces electrical signals in the correct form for the type of radar system.
o The antenna on the other hand, sends these signals out as electromagnetic radiation. The antenna also collects incoming return signals and passes them to the receiver.
o The receiver analyzes the signals and passes it to the display.
o The display allows human operators to see the signal data.
Radar depends on sending and receiving electromagnetic radiation which is regularly in the form of radio waves or microwaves. Electromagnetic radiation is energy that moves in waves at or close to the speed of light. The characteristics of electromagnetic waves depend on their wavelength. Gamma rays and X rays have very short wavelengths. Noticeable light is a tiny slice of the electromagnetic spectrum with wavelengths longer than X rays, but shorter than microwaves.
Radar systems use long-wavelength electromagnetic radiation in the microwave and radio ranges. Because of these long wavelengths, radio waves and microwaves are inclined to reflect better than shorter wavelength radiation, which tends to scatter or be absorbed before it gets to the target. Radio waves at the long-wavelength end of the spectrum will even reflect off of the atmosphere's ionosphere, a layer of electrically-charged particles in the earth's atmosphere.
Radar usually starts it system by sending out signals. The signal bounces off a target object and returns to the radar gun. This signal moves at a steady speed of light, so a computer unit can determine the time it takes for a signal to return.
If the target object is moving towards the radar gun, the frequency becomes higher due to a phenomenon called the Doppler shift. This means a moving police vehicle can exactly estimate the speed of a car approaching it. Police do not have to remain still by the side of the highway to detect speeders with radar guns.
Radar detectors are small devices used by many drivers to identify the presence of radar police units. These radar detectors will pick up the radar gun's signal before the driver speeds his/her vehicle past the police using it.

Why Everyone Should Own a Radar Detector



Radar detectors are very controversial these days. However, they are growing in popularity and more people own radar detectors today than ever before. Let's take a look at some reasons to own a radar detector.


I wish I could say I never speed, but that's just not the case. Actually, there are very few people who can say they never speed. This is such a face-paced life we live; always on the go and late getting there. So let's be as safe as possible. While most people think radar detectors are only for detecting speed traps, they can actually serve as a safety tool. While my mind is on a dozen other things (I know, I should be thinking about my driving...) my speed goes unchecked. Then, alas, my radar detector beeps and brings my attention back to the serious matter of my driving speed. Hopefully, it has alerted me soon enough to avoid a speeding ticket.


We've all seen the sneaky cops who hide behind bushes, just over the hill, around the curve at the bottom of the hill, or behind those bridge abutments. Don't you just grit your teeth when you see that! So why not have your own line of defense? Bear in mind there are a few states that do not allow the use of radar detectors, so be sure to check with your state before purchasing a radar detector. You can be sure the cost of a radar detector is far less than the cost of speeding tickets. Then there's the factor of increased insurance premiums - ouch! And that's a long-term expense!


Do you do a lot of driving for your job or career? Once again, you need to be in a dozen different places an hour ago, so you're driving like mad to get there. How many tickets can you get before you lose your job? How many tickets can you get before your insurance goes through the roof, once again putting your job at jeopardy? It just makes good sense to use a radar detector whenever you're on the road. If you can't help yourself from speeding, then at least use a tool to help protect your driving record and job security.


So, you've decided to purchase a radar detector - now what? There are some important considerations when purchasing a radar detector. For instance, band detection (which detects the range of police radar devises), distance to detection, ability to jam the signal, pricing, even where they are manufactured. So it's important to do your homework. Here are some tips to help you along:


1.  First of all, are they legal in your state - you could face large fines and even confiscation of your unit. The best way to find out is to contact your Secretary of State or local law enforcement office. If you live in Virginia or District of Columbia, don't bother - they're illegal in these areas. If you drive a commercial vehicle, don't bother - they're illegal for use in commercial vehicles, as well as on military bases and most Canadian provinces.


2.  How much do you want to spend? Remember the old saying, "You get what you pay for." That being said, the most expensive radar detector is not necessarily the best one for you. So give some thought to the features you are looking for, which leads us to tip # 3.


3.  There are a lot of radar detectors on the market with a lot of features, such as range, sensitivity, visual alerts, audio alerts, false alarm control, etc. Basically, there are three different types of radar detectors on the market: (A) corded, which are usually mounted on the windshield in the vicinity of your rear view mirror and offer the best range of detection; (B) cordless, which are more transportable and are easier to install, and (C) remote-mount radar detectors which are permanently mounted to your vehicle and are undetectable to thieves.


4.  So what features do you need? Of course, this goes back to your budget - the more features, the more it's going to cost you. At a minimum:


Your radar detector should have a wide band and can pick up the entire X, K, and Ka band. And by the way, you will want different indicators for each one of these bands including a separate flash or beep for each band. You want your radar detector to have at least 110 dB.  Do you like the appearance of the display - Is it clear and large enough to see it? You will most likely want a mute feature and volume control, as well.


Now that you know what features to look for, what type of radar detector do you want that fits in the budget you have to work with. A lot of manufacturers will have an online comparison of their different makes, models and features. This will help you narrow down the manufacturer, and then consider purchasing your item from a reputable website specializing in radar detectors. 


As I mentioned before, you usually get what you pay for, but if you keep with some of the more popular brands, such as Beltronics, Cobra, Escort, Rocky Mountain Radar, Valentine and Whistler, you should be just fine, as they usually offer a wide variety of product with a wide variety of features in all price ranges.


5.  Another consideration - are you going to install it yourself or have it professionally installed. Some radar detectors install as easily as plugging it into your cigarette lighter; others require direct wiring, etc. Most manufacturers offer installation guidelines and schematics for their products on their websites. If you aren't handy enough to install it yourself, most good electronics stores can point you to an auto electronics installation facility.


6. Probably the most important tip I can offer - BUYER BEWARE. As with any purchase, do your homework. Check the warranty and the small print. Can you return it if it's not the correct model for you. What if it's defective - can you return it for your money back or just an exchange or store credit? If you buy from an online store, be sure they are an authorized dealer; give them a call to be sure they're a real store; and, again, read the small print there as well.


Hope you find these tips helpful. Be safe, and have a great trip!

Radar detectors will be able to warn Others of Speed Traps

In the cat-and-mouse game of avoiding police radar, speeders are about get a potent new weapon: each other in an automatic social network. Going on sale today is a system from detector maker Escort, based in West Chester, Ohio. Escort hopes to have "hundreds of thousands" of Escort Live networked devices in place within a year. The system consists of nothing more than a new power cord for an Escort unit, costing $79, that transmits radar sightings to the user's GPS-enabled smartphone. The phone then will automatically transmit the information to all others nearby in the network. About 2 million drivers have Escort units.

What Radar Detector And How It Works

Are you tired of getting pulled over for speeding? If yes, you are ready for radar detector but you should know a little bit more about radar detection and how it works.  You have to know the latest technology police are using to catch speeders.
Radar detector is basically a device which allows you to find out when your car is being tracked by a radar gun, which is the device most police forces use to track other vehicles speed. The way a radar gun works is a radio signal is sent from the policeman's radar gun towards your vehicle, and the signals bounce off and back to the radar gun at a certain speed. If your car isn't moving at all, the radio signals come back at essentially with the same speed. If your car is moving they come back at a faster rate, and this can be measured. It is known as a Doppler effect in physics.

So what factors would be important when selecting a radar detector? First of all not all radars are built the same. Some are more accurate, some are more portable, and some are cordless for quick removal. The corded models are a bit bulkier, but also afford a bit more advance warning since they have a longer range than the cordless variety. Either way, when you are encountered by a radar gun that is tracking your car, you will either get an audible "beep" or a visual light signal that lets you know about it so you can take action and slow down. The problem is, often by the time you get the signal it may already be too late. There is another type of radar signal that most basic detectors aren't even able to read, and that is laser signals. These guns can’t be detected by standard radar detectors, so you may need to get what's called a "jammer" to fully protect yourself. These are illegal in most states though, so if you're caught using one it could lead to a hefty fine.
Another thing to consider is that even a standard radar detector won't smell out the police radar if their radar gun is not currently on active status. The newer guns are "instant on" devices, so you can be cruising down the highway and suddenly get a hit from your radar detector, only a few hundred feet from a standing police officer with a gun in his hand. So even if you have a radar detector it's best to keep your speed down and not rely on it too heavily. It may save you from getting ticket or two but if you disregard speeding laws sooner or later you may maybe caught.
If despite of that you still want to buy radar detector be prepared that the number of choices out there is humongous. Luckily, there are only a few worth buying and we will try to help you to decide which one is the best radar detector for you.

The first question is "How much do you want to spend?"  If number lower than $150 doesn’t buy anything. If your answer between $150 and $200, your best option is to buy a refurbished Escort Passport 8500 from Escort Radar's eBay store. If you have $300 to spend, you should get either an Escort Passport 8500 X50 or a Beltronics RX65. All the radar detectors previously mentioned will serve you well, but if you want extreme performance, you need to bump your budget up to $400 to $500.
If you have $400 to $500, your decision just got very difficult as there are bunches of radar detectors available at that price with different feature sets that you need to consider. The top devices on the market today are the Valentine One, the Escort Redline, the Beltronics STi Driver and the Escort Passport 9500ix. While all excellent performers, each of the have their own pros and cons.
The Escort Redline is currently the undisputed king of sensitivity and will alert further than all other devices in most situations. The Valentine One is the top performer in the area of reaction time and will alert faster than most other devices on the market. The Escort Passport 9500ix is the best radar detector for filtering out false alerts as it has a unique GPS feature that will automatically filter out false signals based on frequency and location.

To help you determine which is right for you, we'll take a look at each of these features separately so you can decide which is the most important to you. Sensitivity should be high on everyone's list as the more sensitive radar detectors will alert the furthest from the police officer radar gun. The more warning time you have, the more time you'll have to correct your speed and slow down. The Escort Redline and the Valentine One are very close most of the time with the Redline slightly edging out the Valentine in most situations. The 9500ix lags behind both, but it will provide enough sensitivity for most situations.

Reactivity is a radar detector's ability to alert to radar sources as quickly as possible. This feature is becoming more and more important as police officers are able to engage their radar guns, get a speed, and disengage them faster than ever. A lot of radar detectors won't even alert at all in a situation like this. Out of the top 4 units listed above, only the Valentine One has great reaction time to super fast radar sources. The Valentine One is known to detect short bursts of radar much more often than both the Redline and the 9500ix.

Selectivity is the radar detector's ability to filter out false alerts. Only the Escort Passport 9500ix has the ability to automatically learn and suppress false alarms by location and radar frequency. If you pass by the same false alert three times, the 9500ix will learn the location and you will not be alerted to that radar source in the future. It's important to note that only that radar source is suppressed, if a new radar source appears in the same location that will cause an alert on this unit. Neither the Redline nor the Valentine have this feature.

Bottom line is, if you are looking for raw detection distance, go with the Escort Redline, if you are looking for the best reaction time, go with the Valentine One, but if you are looking for a radar detector that doesn't alert unnecessarily, go with the Escort Passport 9500ix.

How Leagl It Is To Use Radar Detectors

A good number of the people with cars in the United States have their own radar detectors. Their reason is that they feel that the speed limit at present is very low. Most of the American people are not satisfied with moderate speed while driving. They want to be the fastest driver on the road as well as get to the places they’re going in record time they want to be always in the race.
The use of a radar detector in a passenger vehicle is legal in all states with the exception of Virginia, Washington DC. It also prohibited on military bases. Radar detectors are illegal in all commercial vehicles weighing over 10,000 pounds.  In Canada, the only three provinces that allow their use are Alberta, British Columbia and Saskatchewan.  Many overseas countries also ban their use, such as Portugal, Finland and Spain. 

In areas that radar detectors are illegal, law enforcement use a device called the Spectre that is able to detect the use of radar detector in your car or truck. Laser Jammers and Radar Jammers are illegal in the states of Nebraska, Minnesota, Utah, California, Oklahoma, Virginia, Colorado, Illinois and Washington DC. If you decide to use a laser jammer in one of the states that they are outlawed, consider getting the Blinder M-20 or M-40 or the Lidakek LE-30. The Blinder and the Lidatek are the only laser jammers made today that give minimal "error codes" to the police laser guns.
In an effort to combat speeding in Virginia, law enforcement agencies employ the use of radar guns to measure how fast vehicles are traveling on the roads. In other states, motorists have utilized radar detectors in response to this tactic. But you should know that radar detectors in Virginia are illegal. 

The state of Virginia has banned the use of radar detectors in all civilian vehicles. People who violate this law are subject to a fine. However, the law does not call for demerit points to be issued for possession of a radar detector, and unless the device is being used as evidence, police officers are not permitted to confiscate it. In addition, the law allows police to cite you even if the radar detector is not operational. This prevents would-be violators from disconnecting their radar detectors after being pulled over but before a police officer is able to see it. However, if there is no power source for the device in the vehicle, and if the device is "not readily accessible" by the driver or any passengers, then police officers are not permitted to cite you for violating this law. Under Virginia law, if you are convicted of DUI in the General District Court, you have a right to appeal and get a new trial in the Circuit Court.

In all honesty, radar detectors are not very practical in terms of preventing speeding tickets. In most cases, police officers only turn on their radar guns when they see a vehicle that they think is speeding. So by the time this device picks up the desired radio frequency and you hit the brakes, the police officer has already clocked your speed.
