From The Manufacturer

The Whistler CR90 laser radar detector is a high performance, professional grade dash model which detects all radar guns used today with total band protection, including X-band, K-band, Superwide Ka-band, and laser. Total laser detection identifies Laser Atlanta Stealth mode, Laser Ally, and the new LTI Truspeed S. It's equipped with a pre-installed internal GPS database to alert you to speed and red light traffic camera locations in the United States and Canada, which can be updated via USB. Delivers 360 degrees of complete perimeter protection, detecting signals from the front, sides, and rear. Features Radar Signature ID (RSID) which is a Ka-band radar identifier that displays Ka 33.8, 34.0, 34.3, 34.7, or 35.5 when detecting these common Ka speed radar systems. Laser Signature ID (LSID) indicates the Pulses Per Second (PPS) transmitted by speed laser or other forms of laser sources. The POP Mode detection feature is an advanced speed detection capability that responds to brief bursts of radar. Traffic Flow Signal Rejection (TFSR) helps eliminate alerts from radar based traffic flow sensors and 6 filter modes reduce false alerts caused from other radar detectors. The low emission design makes it difficult to be detected by VG-2 and other radar detector detectors. This laser radar detector includes real voice alerts and an OLED text display that shows alerts and signal strength and contains many other features, such as Stay Alert, vehicle battery saver, 3 city modes, highway mode, and alert priority that make this a top notch detector. Measures 4.93" L x 3.12" W x 1.31" H, and includes the radar detector, a 12V power cord, USB update cord, dash pad, windshield bracket kit, user guide, and a limited 1 year manufacturer warranty.

An Overview On Radar Detectors

A speeding ticket can put a serious damper on your day. Not only will you face a fine of $150 on average, but you’ll also have to deal with the drama of being pulled over by a police officer. Although smartphone apps like Waze can alert you that a police officer is coming up, do you really want to trust your fellow travelers to report one?

The best solution remains the same thing people used to avoid speeding tickets before we had smartphones. A radar detector picks up the emissions produced by police officers’ devices. Today’s top radar detectors are advanced enough to get around the many issues consumers faced in the past with radar detectors. They’ll find the band most often used by officers and filter out the common causes of false alarms.

If you don’t want to give up the crowdsourced approach to traffic alerts, don’t worry. Some radar detectors sync up with an app that helps you access the power of the crowd. This combination of information will ensure you have the best chance possible of knowing when your speed is about to be checked.

One problem with having a radar detector is that the police may be able to detect you have one on board. A device called Spectre can detect radar detectors and potentially lead to a ticket, depending on where you live. In Virginia and the District of Columbia, use of radar detectors is illegal. You can turn your detector off once it sends an alert since you’ll be slowing down anyway. Once you’re safely past the police officer, you can then turn it back on. There are also some radar detectors that claim to be undetectable to Spectre detectors.

Of course, the most important feature is accuracy. It’s important to look for a radar detector that captures all suspected radar incidents without routinely setting off false alarms. Once you have your detector, there are tweaks you can make to ensure it’s as accurate as possible.

DYWM Fun Fact

Speed limits date all the way back to the 1600s, when the colony that later became New York passed a law that wagons, carts and sleighs could not be operated at a gallop. In 1901, Connecticut became the first state to pass a speed limit, which was 12 mph in cities and 15 mph on more rural roads. A national speed limit was finally set in the 1970s to help reduce the impact of high fuel prices. In 1974, a speed limit of 55 mph was set nationwide, at which point traffic fatalities began falling. By 1983, they’d dropped from 4.28 million to 2.73 million.

The Radar Detector Buying Guide

  • As valuable as radar detectors are, it can also help to have fellow travelers alerting you to police officers ahead. The Escort iX Radar Detector and Escort MAX360 Radar Detector connect to a smartphone app that allows users to report all radar and laser encounters, with the information reported as alerts through the detector.
  • If you’re concerned about an officer’s Spectre device detecting you have a radar detector in your vehicle, consider the Cobra Radar Detector. It promises complete immunity to Spectre I radar-detector detectors.
  • Accuracy can be tough to quantify, but the Escort iX Radar Detector uses technology that is often implemented in high-end radar detectors in order to reduce false alarms.
  • Range is also important in a radar detector. The Valentine One notifies drivers well in advance of a potential radar incident. Its rear-facing antenna can also keep a lookout for any radar behind you as you travel.
  • False alarms are an ongoing issue with radar detectors. Both the Valentine One and Cobra Radar have a bad habit of picking up every hint of radar. The Valentine One doesn’t mute DSP and GPS signals, which means you’ll probably be alerted to every radar you pass.
  • One popular feature on the Escort MAX360 Radar Detector is its directional arrows, which show you the direction of the radar in relation to your car. However, the arrows can have a slow reaction time, making them not as useful.
  • Readability is important in your radar detector. Alerts mean nothing if you can’t decipher them. The controls on the Escort iX Radar Detector are clearly labeled, with all functions easy to understand. The Cobra Radar Detector’s display is notably easy to read, even in bright sunlight.
  • You don’t have to blow your savings to protect yourself against speeding tickets. The Cobra Radar Detector sells for close to $50, making it by far the least expensive. The Escort iX Radar Detector retails for more than $300, while both the Escort MAX360 and Valentine One detectors are more than $400.
