Using the radar calibration records will not ensure you get out of a speeding ticket. However, the reliability of radars depends on police keeping them in good working order. Calibration is an essential part of necessary maintenance. So if you plan to fight a radar based speeding ticket, you usually want to get the radar calibration records.

According to the operating manuals that come with the police radar, each radar unit is said to be calibrated with tuning forks before each work shift and also before and after the detection of each speed violation to ensure accuracy. The tuning forks are also delicate creatures: if they are not kept in a box that protects them from moisture and shock, they will become inaccurate.

But if you attend any traffic court trials, you’ll find that nearly all officers swear they calibrated their speed cameras just before issuing the ticket. What they usually mean is that they flipped a switch built into the radar unit itself and then switched it back to regular operation. Radar devices often have an internal calibration function. But these internal calibrators are usually not as accurate as tuning forks. If you ask about calibrating with a tuning fork and the officer who issued you a ticket didn’t witness it, that may be enough to keep you off the hook.

Yes, it is possible – but it is difficult and you certainly do not want to attempt it without the help of an experienced lawyer. Radar gun evidence is considered reliable in court, but radar guns can provide inaccurate readings if not properly calibrated or used properly.

If you can provide evidence that points to an inaccurate reading, you may have reasons to dismiss your speeding ticket. Let’s discuss how radar guns work, why and when you should fight the ticket, and how best to prepare your defenses.

How radar guns measure speed – and how they can get it wrong

A radar gun detects your speed by bouncing a radio wave off your vehicle as you drive. It measures the time (in nanoseconds) it takes for the radio signal to reach your vehicle versus the time it takes for the signal to bounce back to the gun. Since radio waves travel at a constant speed (i.e. the speed of light), the difference between these two readings can be used to calculate how fast your vehicle was going. The new LiDAR turrets some cops are using work on a similar concept – they simply use laser light instead of radio waves to measure your speed.

Regardless of what method the officer used to monitor you (radar or LiDAR), these weapons are not infallible. Here are some ways they can produce an incorrect reading:

Incorrect calibration. If a radar gun hasn’t been properly (or recently) calibrated, it can give you a bad reading – just like a scale that’s not calibrated to “zero” will give you the wrong weight.

If a radar gun hasn’t been properly (or recently) calibrated, it can give you a bad reading – just like a scale that’s not calibrated to “zero” will give you the wrong weight. weather conditions. Bad weather, especially strong winds, can affect the performance of the radar gun.

Bad weather, especially strong winds, can affect the performance of the radar gun. user error. An improperly trained police officer can mispoint the radar gun, which could result in it detecting a vehicle other than yours.

Why You’ll Want to Dispute Your Radar Gun Speed ​​Ticket

Many people find it easier to pay for the ticket than to fight it in court – and you certainly have every right to do so. However, you need to know that by paying your parking ticket you are effectively pleading guilty to the crime of speeding. Depending on the circumstances of your case, this can have some undesirable consequences. Some reasons it might be in your best interest to fight the ticket are:

Paying for the ticket can earn points on your ticket, which can lead to an increase in your insurance premiums.

If you have too many previous points on your driver’s license, the ticket could get you over the border and trigger an automatic suspension of your driver’s license.

If your Virginia speeding ticket is for “reckless driving at speed” — that is, if you were measured at more than 20 mph over the posted speed limit, or generally over 80 mph — that’s a Class 1 misdemeanor, the This can result in hefty fines and even imprisonment.

Ways we can challenge a radar gun reading

Radar gun readings can be compelling evidence in traffic courts, but a good traffic attorney can still effectively challenge that evidence in certain cases. Some ways we can do this are:

Review of current radar gun calibration certificate.

If the certificate is old (meaning the gun hasn’t been calibrated in a while) or if it’s filled out incorrectly, this may be enough to reject the ticket.

Assessment of weather conditions on the day of the ticket.

If you were driving in bad weather when you were stopped, we can examine the weather conditions and the officer’s position when he stopped you to determine if the readings were affected by the weather.

claim user error.

If the officer wasn’t properly trained to use the gun or stopped you in heavy traffic, they may have pointed the gun at another vehicle, causing an incorrect response.

quote error rate.

If you were at or near the speed threshold to be charged with reckless driving, the device’s margin of error might be enough to reduce the charge to simple speeding and save you from a misdemeanor conviction.

Radar speeding tickets

The majority of California speeding violations are issued through the use of radar. As a result, one of the most common questions we get is, “Can I fight a speeding ticket with radar?” The answer is yes. In fact, radar is far more likely to invalidate a speeding ticket than other methods of speed enforcement.

In California, all law enforcement agencies must comply with the California Vehicle Code to issue radar speeding tickets. In addition, each law enforcement agency has its own policies and procedures for issuing valid radar speeding tickets. Some law enforcement agencies have stricter requirements than those set by the vehicle code for radar speeding.

Therefore, successfully combating a radar speeding ticket requires a thorough understanding of the policies of the particular law enforcement agency that issued the radar speeding ticket, as well as the technicalities of radar technology. It’s also important to know the state’s vehicle code sections, which set the rules for radar issuance of speeding tickets.

Common arguments for countering speeding tickets with radar

The majority of people already know or have heard or read that in order to issue a radar speeding ticket, the police officer must have the radar unit properly calibrated. In addition, the officer must have completed a radar training program and obtained a radar operator certificate in order to issue a valid radar speeding ticket. As a result, most people try to fight a radar speeding ticket by arguing that the officer’s radar is not properly calibrated or the officer is not certified to operate the radar. Unfortunately, the matter is not so simple, since law enforcement agencies are well aware of the requirements for using radar. In most cases, the officer will bring a copy of the officer’s radar calibration record and radar certificate to the court, and before the defendant can address the issue, the officer will show the defendant and/or the judge that both requirements have been met.

Then the next common but ineffective defense against radar tickets is the argument that the officer’s radar picked up the speed of another vehicle (a larger vehicle). Although this can be a real and valid argument, there must be evidence to show that the claim is valid or the judge will not accept this argument. For this reason, in order to circumvent speeding tickets by radar, one must have a detailed technical knowledge of radar technology to be able to argue that the specific conditions on the roadway could have interfered with the proper operation of the radar and led to an erroneous result.

Another ineffective argument discussed in many blogs is the cosine effect. The term “cosine effect” on radar sounds very impressive and technical to most people. Although the cosine effect actually produces an erroneous radar speed, the error caused by the cosine effect actually shows a lower speed than the actual speed of the target vehicle. Therefore, claiming that the speed recorded by the radar was wrong due to the cosine effect may not be as effective as one might think.

How to avoid speeding tickets with radar?

By now you understand that the common arguments against radar speeding tickets may seem like strong arguments, but in reality they don’t work in traffic courts. Therefore, in order to avoid a radar speeding ticket, one must use arguments that can be backed up by evidence or documentation to show the judge that there is at least a possibility that the officer made a mistake or the radar unit made a mistake Error generated speed.

Back to the requirement that a radar used to issue a speeding ticket must be calibrated. Assuming the officer provides a copy of the radar calibration certificate, a person must also check the date the radar was last calibrated and compare this to the requirements of the vehicle code and the policy of the law enforcement agency that issued the speeding ticket by radar. If the date the radar unit was last calibrated was longer than required, this becomes a very strong argument that the radar speeding ticket is not valid.

Another simple point to check is to compare the radar unit number on the radar certificate with the radar unit number that the officer recoded on the citation to see if those numbers match. If the numbers do not match, the radar certificate does not belong to the radar that was used in the speed enforcement and the officer would need to present the radar certificate for the specific radar unit that was actually used to issue the ticket.

There are also other important items to check on the radar calibration certificate such as the calibration of the antennas and the tuning fork certificate used to verify radar accuracy. Another important point that can show that the radar unit was not accurate is to look at the maintenance or repair history of the specific radar unit. If the recording shows that the radar required frequent repairs, this could be an argument that the particular radar may need calibration more frequently than necessary, even though the certificate deadline has not yet expired.

On this page we have tried to describe just a few of the many detailed arguments that can lead to a speeding ticket being dismissed in traffic court. In each case, the details will differ in terms of equipment, road conditions, the specific type of radar and the control vehicle. For this reason, it is very difficult for a layperson to come up with a good defense against a radar-issued speeding ticket.

This is why most people use our service to fight speeding tickets with radar.

Tuning forks are two-pronged metal forks most commonly used as a pitch standard for tuning musical instruments. However, they also play a key role in ensuring the accuracy of a police officer’s radar readings.

How are tuning forks used by law enforcement?

Tuning forks are used to calibrate the radar guns that officers use to track speeding vehicles. The officer is supposed to calibrate the radar at the beginning and end of each shift to ensure it is providing accurate readings. The tuning fork itself should be calibrated every six months to ensure it is producing a frequency consistent with a vehicle moving at the target speed.

How does this affect your defenses against reckless driving?

The most common scenario where tuning forks become a crucial piece of evidence is when you’ve been charged with reckless speeding for driving more than 20 mph over the legal speed limit or over 85 mph regardless of the posted speed limit . Virginia law states that a tuning fork calibration is only valid for six months. If the calibration occurred more than six months before the date of your stop, attorney can use that evidence to support your defense.

The serial number of the tuning fork must appear on the calibration certificate for the calibration to be valid. Ideally, the serial number should also be listed on your ticket. Different types of radars can use different frequencies, so it’s important for an officer to be able to determine which tuning fork was used to verify the radar’s accuracy.

Failure by the officer to provide sufficient evidence that the tuning fork calibration is accurate casts doubt on the accuracy of the radar reading. If you’re only slightly over the limit for reckless speeding, that doubt is often enough to get your fee reduced or waived.

A few months ago I received a really cool and pretty useful gadget. About the size of a cell phone or point-and-shoot camera, the Pocket Radar is a nice device to slip in your pocket, especially if your kids are playing sports or learning about physics. With Pocket Radar you can quickly and easily determine the speed of any object or person by pointing at the object or person and clicking a big red button.

If you think about it, the ability to find the speed of any object can be very useful and informative. The most obvious use case that comes to mind is that of a baseball field. By simply pointing at the ball (note it’s better to be either directly in front of or behind the ball rather than at an angle – this will give you better accuracy) you can find out how fast your son or daughter or someone else is going is player throws the ball.

There are many other use cases as well:

At a track and field event, you can determine the speed of the runners

Calculate the speed of a golf swing or the ball itself

As race cars rush by, take the speed of those cars with you

Find out if cars are speeding in your neighborhood

When I first took the Pocket Radar out of the box, the first thing my daughter and I tested was the ceiling fan speed. This type of test is particularly difficult due to the circular motion, and being behind or in front of the fan is a bit difficult to accurately determine the speed. But we could tell it’s about 18 mph.

We later took our bikes to a playground and practiced racing towards the person holding the pocket radar as fast as we could. It was pretty fun to see who could go faster but be aware that in these types of races or speed contests there is a risk of getting a little out of control and possibly falling so make sure you wear and keep helmets things under control.

get techie

So is Pocket Radar really that accurate? Well I would definitely say it is. Using a combination of Doppler radar and microwave and antenna components, the pocket radar gives quick results, and they seem spot on from my non-scientific testing. According to the documentation, it is accurate to 1 MPH and can detect speeds between 7 and 375 MPS.

How does it work? Essentially, it emits a tiny, invisible pulse of radio waves as soon as the big red button is pressed. As soon as these beams hit an object, a smaller part of it is reflected back and the Pocket Radar receives this and quickly calculates the object’s speed based on the difference between the two waves.

In order to get an accurate measurement, you must not let the object pass in front of you (e.g. from left to right) because you cannot detect the change in distance between the pocket radar and the object.

To get the most accurate reading, the object needs to be as close to the line as possible. However, remember that this can be dangerous, so don’t jump in front of a car coming your way. Be sure to practice your speed measurement safely. There’s a great chart in the user guide (which is pretty detailed by the way) showing how the angle of the object can affect the “measured speed”:

And to put this in perspective, below is an example of the variance when calculating a baseball pitch speed:

In terms of security, the amount of energy coming from Pocket Radar is actually much less than that coming from a cell phone, especially when you are conversing. The Pocket Radar is in an off position until you press (and optionally hold) the red measurement button. According to their website, you get more radiation from a Bluetooth headset or from standing next to a microwave oven.

With the pocket radar

To get started with the Pocket Radar, all you have to do is insert the 2 AAA batteries. Each set of batteries is enough for about 10,000 speed measurements. As soon as you switch on the pocket radar, you will get a reading of the previous measurement, as the device saves the last 10 speed measurements. If the button is not pressed for 30 seconds, it will turn off automatically to save battery power.

The Pocket Radar itself is incredibly easy to use. Just point to the object you want to get a speed reading of and press the red button. Within a second, the LCD screen will display the speed of that object, assuming you’re aiming at the object correctly.

However, if you want a continuous readout of an object’s speed, you can hold down the red button and the display will then update as you track the object, showing the real-time speed while you hold down the button. However, this method will drain your battery a bit faster.

One thing I received with my reviewer’s sample was a tuning fork. This was actually a pretty interesting experiment that you can use to test the Pocket Radar’s accuracy. The included tuning fork was one that vibrates at exactly 65 MPH. You simply hit the fork to make it vibrate and then point the Pocket Radar directly at it and you will see the gauge read 65 MPH. Below is the test tuning fork:

And then the pocket radar pointed to the vibrating tuning fork and got a reading of 65 MPH. The nice thing is that you don’t have to adjust the Pocket Radar as it comes pre-calibrated from the factory.

You can change the setting from miles (MPH) to kilometers (KPH), but you can also choose meters per second (MPS) or feet per second (FPS).

You can measure the speed of a car up to half a mile away. Remember, the smaller the object, the closer you usually need to be. For example, a thrown ball requires you to be much closer (e.g. 120 feet for a baseball) compared to a moving vehicle.

The Pocket Radar site has one of the largest and most complete FAQs I’ve seen on any product. So if there’s a scenario you have questions about or just need to dive deep into the technology behind Pocket Radar, this is the first place to start.

It is important to remember that the Pocket Radar is NOT a radar DETECTOR. It actually emits radar waves. So while you’re not preventing yourself from getting a speeding ticket, you can actually help document speeders in your neighborhood and get YOU a speeding ticket! However, I’m tempted to take the pocket radar in my car to point at the sports cars that speed by with radar detectors on their front windows to trigger the detector and hopefully slow them down!

The Pocket Radar is almost like a miniature science experiment when you use it with your kids. Not only is it a great distraction or tool when you’re on the go and active, you can use it to teach physics and math too. For example, you can determine your own speed by aiming the Pocket Radar at a large stationary object. Reading works on the same principle where you are stationary and aim it at a moving object.

But what about relative speeds? This is a great little experiment to do with your kids in the car. They can have fun doing additions while calculating an object’s true speed. First you have to explain to them that when you point at a car moving in the same direction as you, you are only measuring its speed relative to yours, i.e. if you are driving 60 MPH and the reading on a car’s pocket radar, passing you shows 15 MPH, that means the car went 75 MPH. Conversely, you can also determine the speed of objects coming towards you. If you know your speed is 30 MPH and the pocket radar reading is 75 MPH, you know the car coming your way is going 45 MPH (75-30 = 45). This is a great way to practice addition and subtraction in the car.

The Pocket Radar retails for $249 but is currently available for purchase on the Pocket Radar website for $199. You can currently pick it up on Amazon for $194.75. It weighs 4.5 ounces with batteries installed and measures 4.7″ x 2.3″ x 0.8″ (about the size of a cell phone).

If you’re looking for a handy little device that really comes in handy, especially if your kids play sports or races or bike rides or anything that requires a bit of speed, then you should definitely get yourself a pocket radar. As an educational item, a sporting necessities or just a great new gadget, the Pocket Radar is definitely a good device to have. With its instant function, quick and easy readings and functions, and compact size, it’s pretty clear that this is an essential piece of equipment to have in your tech tools bag.

frequently asked Questions

What is the difference between the Ball Coach Radar and the Smart Coach Radar?

The Smart Coach Radar was developed based on feedback from top MLB and collegiate coaches on what else they would like to see added to the Ball Coach Radar. The same radar technology used in the Ball Coach Radar is used in the Smart Coach Radar, but much more has been added. Both are specifically designed to track a ball in flight and automatically find the highest speed for you. This applies to throw speed and exit speed from the racquet, as well as other types of ball speeds. Both have a range of up to 120 feet on a baseball and are great training and coaching tools for all types of ball sports. The Smart Coach Radar adds connectivity via Bluetooth and USB so it can work with the Pocket Radar Companion App to provide a host of additional features like speed embedded in video, remote display and remote control. It also allows you to track and export your data. The app enables several high-quality training features, as you can see in the comparison table below. Via the USB connection, the Smart Coach Radar can be used with the Pocket Radar brand Smart Display for outdoor viewing in bright sunlight. The Smart Coach Radar can also be powered by an external USB power supply so you can run it for many hours without worrying about battery life. Select this link to learn more about the Smart Coach Radar.

What is the difference between the Ball Coach radar and the Classic model?

Measuring the speed of a ball in flight is a unique challenge because it slows down significantly due to air resistance. In order to get the fastest speed of the ball right at the beginning of the flight, you need to take the measurement at the right time. For example: A baseball field that is 80 MPH when released from the pitcher’s hand will only be about 72 MPH when it crosses the plate. A tennis ball can be slowed by over 20 MPH from racquet strike to impact.

New technology has been added to the ball trainer, specifically designed to track a ball in flight and automatically find the highest speed for you. Just hold down the blue button throughout the flight or put it in steady on/auto trigger mode. It also finds a ball near other objects, such as a swinging bat or bat. This feature allows you to use the ball trainer radar to measure exit velocity when exiting the club. This is the only direct measure of punching power. With a range of up to 120 feet on a baseball, the Ball Coach Radar is a great training and coaching tool for all types of ball sports. This is sufficient range for use behind the backstop on most high school fields, but it’s not intended for use as a long-range radar gun to kick back in the stands.

The Classic model works with a manual trigger just to take an instant measurement. You must set the trigger so that you want to take the measurement. Repeat mode takes a new measurement every ¾ seconds, which is ideal for objects that move for several seconds or more, such as cars/vehicles and runners. Replay mode will not work for a field because a baseball field at speeds over 60 MPH is only airborne for less than ¾ of a second. In snapshot mode, tapping the red button like a spacebar on a computer at the point where you want to take the measurement can be a challenge. When the object is rapidly decelerating, like a ball in flight, it is difficult to find the right trigger timing to always capture the ball’s fastest speed.

How long do the batteries last?

The Ball Coach Radar is powered by two AAA batteries. How long they last depends on their quality. – Using standard alkaline batteries (included with unit) the radar provides >2000 readings when manually triggered and >1 hour when used in ‘continuous’ mode. – Using rechargeable NiMH batteries (not included with unit), the radar provides >4,000 readings when manually triggered and >2 hours when used in continuous mode. Manual release: Long press the button before releasing the ball. Release the button after the speed is displayed. Constant-On/Auto-Trigger Mode: Allows hands-free use of the device with a tripod. The battery indicator on the LCD display helps you determine when the batteries need to be replaced. The battery indicator is calibrated for 1.5 volt alkaline batteries. When using rechargeable 1.2 volt nickel metal hydride batteries, the battery gauge may read slightly lower initially, although the batteries will last much longer.

How accurate is Ball Coach’s radar?

It’s very accurate (check out the radar comparison video above). Pocket Radar technology has been independently tested and certified to be +/- 1 MPH (+/- 2 KPH) accurate. The tests were conducted by the Police Radar Test Laboratory, which is approved by the National Highway Traffic Safety Administration (NHTSA) and the International Association of Chiefs of Police (IACP), which certifies all radar guns in the United States and Canada for use by law enforcement. All radar guns only measure the relative speed of an object in a direct direction towards or away from the radar antenna. If you point a pocket radar (or any radar device) at an object that is moving sideways instead of directly towards or away from you, it will show a very slow speed – not the exact speed. This is because an object moving at right angles to a radar is only moving towards or away from that radar at a very slow relative speed. To get the most accurate speed measurement, you need to point the Pocket Radar antenna at a moving object and be as close as possible to the direction of movement of that object. Of course you must be safe when using the product, NEVER place yourself or others in a position where you could be hit by a moving object.

What guarantee is given?

2 years. The Ball Coach Radar is built very robust. With proper care, it will last a very long time.

What is the range of the Ball Coach Radar?

A radar’s range depends on the size of the object being measured and how well it reflects radio waves. For a baseball-sized object, the range is 120 feet. For an object the size of a volleyball, the range is 200 feet. *Note: This is a sufficient range for training and coaching applications, or measuring speed just past the backstop on most high school fields. It is not intended for long-distance baseball scouting from the back of the stands.

How does it compare to the other bigger pro radar guns?

Most handheld radars are called radar guns because they are held like a large gun. They contain a radar transmitter that uses a large antenna called a horn. It’s usually cone-shaped and actually looks like a megaphone. It’s long and the radar unit or gun needs to be big to fit the horn antenna. All Pocket Radar™ models use a much smaller, flat antenna array to produce the same type of focused beam shape that the horn antenna produces. For this reason, and many other proprietary inventions, Pocket Radar products offer the distinct advantage of much smaller size. Pocket radar products also use less power than the larger radar guns. Pocket Radar technology is designed to give you a very useful range at an affordable price in a very small size. It has a shorter range than some of the most expensive guns, but a much longer range than the less expensive larger guns. The Pocket Radar Ball Coach™ model can report baseball firing speed from up to 120 feet away. This range is sufficient for training and coaching applications, or measuring speed just past the backstop on most high school fields. It is not intended for long-distance baseball scouting from the back of the stands. The Pocket Radar products give you the same or better accuracy than the larger, more expensive radar guns. However, they don’t have quite as much range as the most expensive radar guns. The Ball Coach radar is intended for coaching and training in sports. If you absolutely need to capture the speed of a baseball right out of the pitcher’s hand from a very long distance or back in the stands, you may need a much more expensive radar gun. For the vast majority of applications, the Pocket Radar products offer a very portable and economical solution that is much more convenient and very easy to use.

Does it ever need to be calibrated?

The Pocket Radar™ products are all based on much newer technology than the big radar guns. It is very stable and keeps the factory calibration. No further calibration is required. You can check the calibration with a special pocket radar calibrated tuning fork. This tuning fork features the Traffic Advisor™ professional traffic engineering model. If you wish to purchase a calibrated tuning fork for use with a different model of Pocket Radar™, please contact us at [email protected].

Does it work through other objects, such as B. a backstop?

All radar guns work with reflected radio waves. The beam will travel through objects that allow radio waves to pass, such as a glass windshield or a metal fence with large openings in it, but the range may decrease slightly because a small portion of the signal reflects off the metal fence and doesn’t get through. The radio waves from a Pocket Radar™ product will not penetrate solid metal objects or conductive walls. It easily fits through a chain link fence that has openings in the mesh that are similar in size or larger than the radar lens on the back of the Pocket Radar.

Can I measure the exit velocity of a bullet?

The Ball Coach™ Radar has a wealth of technology specifically designed to detect the speed of the ball as it leaves the racquet. This gives you the only direct measure of punching power. This is often referred to as exit velocity, or sometimes ball exit velocity. The Ball Coach radar can measure exit velocity during shot practice, off the tee, soft toss or live pitching. Using it with live pitching behind the batter will give you the speed of the incoming pitch and the exit speed out of the bat as long as it’s a well-hit ball that has an exit speed faster than the incoming pitch.

Why do I sometimes see readings that I can’t explain?

All speed radar guns are susceptible to interference, which can sometimes cause inexplicable or random readings, often referred to as “ghost” readings. There are two main sources of these ghost images, electrical interference and moving objects. There are many sources of electrical interference, including things like cell phones, computer monitors, fluorescent lights, neon signs, radios, etc. Any object that vibrates, moves, or rotates can also create ghosting. Things like engines, fans, propellers can often be invisible behind covers or other objects but still be detected by your radar. If you experience these types of random readings, change your position to try to point the radar away from the jamming source.

Can I export the recorded data?

No, the Ball Coach Radar does not have an interface to transfer data to another device. To view the previous measurements, scroll through them by tapping the black “RECALL” button. If you are interested in extracting data from a Pocket Radar™ device, please contact us to talk more about your application so we can consider it for future releases.

Pocket Radar™ products use a Doppler radar signal acquisition and processing system in conjunction with redesigned microwave and antenna components to deliver powerful performance in devices compact enough to easily fit in a shirt pocket.

In developing the world’s most compact speed radars, we had to completely re-evaluate, redesign and rebuild almost every aspect of traditional radar technology. By combining Pocket Radar’s proprietary digital signal processing algorithms and state-of-the-art intelligent target acquisition techniques, we are able to provide users with industry-leading accuracy and velocity measurement in devices that are a tiny fraction of the size of traditional velocity radar guns.

From the world’s smallest certified, accurate speed radar to the only radar gun designed specifically for coaching and training, Pocket Radar has developed a revolutionary line of products to meet your speed measurement needs. Each Pocket Radar design includes exceptional performance and technology that fits in the palm of your hand. Pocket Radar products are convenient and durable enough for everyday use by everyone from professionals to amateurs, to national championship-winning coaches and anyone interested in speed.

How it works

Pocket Radar products are Doppler speed radar systems.

They work as a speed detector by emitting a small pulse of radio waves in an invisible focused beam, similar in shape to a flashlight beam.

When the radio wave hits an object moving towards or away from one of the pocket radars, a small part of the wave is reflected back.

The moving object modifies the reflected radio wave based on how fast it is moving directly toward or away from the Pocket Radar device.

The device then receives the reflected radio wave and compares it with the originally transmitted radio wave. It then calculates the speed of the moving object based on the difference between the two radio waves.

Note that any pocket radar model, like all Doppler speed radars, can only measure the speed of a moving object that is fairly close to the direction of the radio wave beam. You cannot measure side-to-side motion via the radio wave beam. (NOTE: Never put yourself or others in a position where someone could be hit by the moving object!)

The focused beam comes from the radar lens on the back of the device, just behind the display.

Hold the device straight up, like a camera phone, with the radar lens beam aimed directly at the moving object you want to measure. Then “tap” or “hold” the larger button as if taking a picture while the target moves. The speed(s) will be shown on the display.

If the device’s display is off and you missed the last speed reading, just press the little black button and it will show up again. Continued tapping of the small black button will recall previous speed readings.

Tuning forks are two-pronged metal forks most commonly used as a pitch standard for tuning musical instruments. However, they also play a key role in ensuring the accuracy of a police officer’s radar readings.

How are tuning forks used by law enforcement?

Tuning forks are used to calibrate the radar guns that officers use to track speeding vehicles. The officer is supposed to calibrate the radar at the beginning and end of each shift to ensure it is providing accurate readings. The tuning fork itself should be calibrated every six months to ensure it is producing a frequency consistent with a vehicle moving at the target speed.

How does this affect your defenses against reckless driving?

The most common scenario where tuning forks become a crucial piece of evidence is when you’ve been charged with reckless speeding for driving more than 20 mph over the legal speed limit or over 85 mph regardless of the posted speed limit . Virginia law states that a tuning fork calibration is only valid for six months. If the calibration occurred more than six months before the date of your stop, attorney can use that evidence to support your defense.

The serial number of the tuning fork must appear on the calibration certificate for the calibration to be valid. Ideally, the serial number should also be listed on your ticket. Different types of radars can use different frequencies, so it’s important for an officer to be able to determine which tuning fork was used to verify the radar’s accuracy.

Failure by the officer to provide sufficient evidence that the tuning fork calibration is accurate casts doubt on the accuracy of the radar reading. If you’re only slightly over the limit for reckless speeding, that doubt is often enough to get your fee reduced or waived.

A few months ago I received a really cool and pretty useful gadget. About the size of a cell phone or point-and-shoot camera, the Pocket Radar is a nice device to slip in your pocket, especially if your kids are playing sports or learning about physics. With Pocket Radar you can quickly and easily determine the speed of any object or person by pointing at the object or person and clicking a big red button.

If you think about it, the ability to find the speed of any object can be very useful and informative. The most obvious use case that comes to mind is that of a baseball field. By simply pointing at the ball (note it’s better to be either directly in front of or behind the ball rather than at an angle – this will give you better accuracy) you can find out how fast your son or daughter or someone else is going is player throws the ball.

There are many other use cases as well:

At a track and field event, you can determine the speed of the runners

Calculate the speed of a golf swing or the ball itself

As race cars rush by, take the speed of those cars with you

Find out if cars are speeding in your neighborhood

When I first took the Pocket Radar out of the box, the first thing my daughter and I tested was the ceiling fan speed. This type of test is particularly difficult due to the circular motion, and being behind or in front of the fan is a bit difficult to accurately determine the speed. But we could tell it’s about 18 mph.

We later took our bikes to a playground and practiced racing towards the person holding the pocket radar as fast as we could. It was pretty fun to see who could go faster but be aware that in these types of races or speed contests there is a risk of getting a little out of control and possibly falling so make sure you wear and keep helmets things under control.

So is Pocket Radar really that accurate? Well I would definitely say it is. Using a combination of Doppler radar and microwave and antenna components, the pocket radar gives quick results, and they seem spot on from my non-scientific testing. According to the documentation, it is accurate to 1 MPH and can detect speeds between 7 and 375 MPS.

How does it work? Essentially, it emits a tiny, invisible pulse of radio waves as soon as the big red button is pressed. As soon as these beams hit an object, a smaller part of it is reflected back and the Pocket Radar receives this and quickly calculates the object’s speed based on the difference between the two waves.

In order to get an accurate measurement, you must not let the object pass in front of you (e.g. from left to right) because you cannot detect the change in distance between the pocket radar and the object.

To get the most accurate reading, the object needs to be as close to the line as possible. However, remember that this can be dangerous, so don’t jump in front of a car coming your way. Be sure to practice your speed measurement safely. There’s a great chart in the user guide (which is pretty detailed by the way) showing how the angle of the object can affect the “measured speed”:

And to put this in perspective, below is an example of the variance when calculating a baseball pitch speed:

In terms of security, the amount of energy coming from Pocket Radar is actually much less than that coming from a cell phone, especially when you are conversing. The Pocket Radar is in an off position until you press (and optionally hold) the red measurement button. According to their website, you get more radiation from a Bluetooth headset or from standing next to a microwave oven.

With the pocket radar

To get started with the Pocket Radar, all you have to do is insert the 2 AAA batteries. Each set of batteries is enough for about 10,000 speed measurements. As soon as you switch on the pocket radar, you will get a reading of the previous measurement, as the device saves the last 10 speed measurements. If the button is not pressed for 30 seconds, it will turn off automatically to save battery power.

The Pocket Radar itself is incredibly easy to use. Just point to the object you want to get a speed reading of and press the red button. Within a second, the LCD screen will display the speed of that object, assuming you’re aiming at the object correctly.

However, if you want a continuous readout of an object’s speed, you can hold down the red button and the display will then update as you track the object, showing the real-time speed while you hold down the button. However, this method will drain your battery a bit faster.

One thing I received with my reviewer’s sample was a tuning fork. This was actually a pretty interesting experiment that you can use to test the Pocket Radar’s accuracy. The included tuning fork was one that vibrates at exactly 65 MPH. You simply hit the fork to make it vibrate and then point the Pocket Radar directly at it and you will see the gauge read 65 MPH. Below is the test tuning fork:

And then the pocket radar pointed to the vibrating tuning fork and got a reading of 65 MPH. The nice thing is that you don’t have to adjust the Pocket Radar as it comes pre-calibrated from the factory.

You can change the setting from miles (MPH) to kilometers (KPH), but you can also choose meters per second (MPS) or feet per second (FPS).

You can measure the speed of a car up to half a mile away. Remember, the smaller the object, the closer you usually need to be. For example, a thrown ball requires you to be much closer (e.g. 120 feet for a baseball) compared to a moving vehicle.

The Pocket Radar site has one of the largest and most complete FAQs I’ve seen on any product. So if there’s a scenario you have questions about or just need to dive deep into the technology behind Pocket Radar, this is the first place to start.

It is important to remember that the Pocket Radar is NOT a radar DETECTOR. It actually emits radar waves. So while you’re not preventing yourself from getting a speeding ticket, you can actually help document speeders in your neighborhood and get YOU a speeding ticket! However, I’m tempted to take the pocket radar in my car to point at the sports cars that speed by with radar detectors on their front windows to trigger the detector and hopefully slow them down!

The Pocket Radar is almost like a miniature science experiment when you use it with your kids. Not only is it a great distraction or tool when you’re on the go and active, you can use it to teach physics and math too. For example, you can determine your own speed by aiming the Pocket Radar at a large stationary object. Reading works on the same principle where you are stationary and aim it at a moving object.

But what about relative speeds? This is a great little experiment to do with your kids in the car. They can have fun doing additions while calculating an object’s true speed. First you have to explain to them that when you point at a car moving in the same direction as you, you are only measuring its speed relative to yours, i.e. if you are driving 60 MPH and the reading on a car’s pocket radar, passing you shows 15 MPH, that means the car went 75 MPH. Conversely, you can also determine the speed of objects coming towards you. If you know your speed is 30 MPH and the pocket radar reading is 75 MPH, you know the car coming your way is going 45 MPH (75-30 = 45). This is a great way to practice addition and subtraction in the car.

The Pocket Radar retails for $249 but is currently available for purchase on the Pocket Radar website for $199. You can currently pick it up on Amazon for $194.75. It weighs 4.5 ounces with batteries installed and measures 4.7″ x 2.3″ x 0.8″ (about the size of a cell phone).

If you’re looking for a handy little device that really comes in handy, especially if your kids play sports or races or bike rides or anything that requires a bit of speed, then you should definitely get yourself a pocket radar. As an educational item, a sporting necessities or just a great new gadget, the Pocket Radar is definitely a good device to have. With its instant function, quick and easy readings and functions, and compact size, it’s pretty clear that this is an essential piece of equipment to have in your tech tools bag.
