How to Choose The Best Car Radar Detectors under $100 for You?

The best radar detectors are capable of picking up the low-powered radars used in today's radar guns and speed cameras. The best radar detectors can detect all of today's radar signals for speed detection (K-band and KA-band), as well as legacy bands (X-band). Today's best radar detectors utilize GPS technology, allowing speed, time, and location functions. Available in K40 Platinum100 Portable Radar & Laser detectors is the capability of showing the current speed of the vehicle as well as the compass directions. 

The Escort MAX 3 also features Auto-Learning Technology, which adjusts itself based on the driving style and habits of your car. A highly selective detector is capable of distinguishing between bands of radar and laser, as well as signals from emergency vehicles or traffic signs. Selectivity refers to the ability of the detector to pick up police radar, while also rejecting devices like automatic garage door openers and microwave ovens, which can run at frequencies that are close together. The sensors do detect police radar, thus their generic name, although they usually detect even the most advanced LIDAR (laser)-based detectors. 

Not only do the most advanced modern detectors detect police radars and warn you of their presence, they also use internal transmitters to produce similar radio signals, mixing them in with radio noise in order to thwart an accurate rate reading from the officer's radar guns. In addition to the way a radar detector works and what kind of signals it detects, the main difference between older radar detectors and the latest, higher-end devices is how many false alarms are given. Law enforcement uses several different types of radar devices in their pursuits of speeders. 

The Escort ix has excellent radar and laser range made possible by forward-facing and back-facing antennas that provide 360-degree coverage, a digital signal processor that helps filter false alarms, and it has a speed-based sensitivity so that as you navigate around a parking garage at slower speeds, the radar detector will ignore things like automated doors. It offers exceptionally long-range, 360-degree protection from radars and all forms of speed-detection lasers, and features best-in-class build quality. At longer ranges, the Escort Passport S55 can pick up speed detection in the frequency bands ranging from superwide Ka through to X through K. The S55 can pick up laser speed detection as well. The Redline 360c offers great detection over a long distance, built-in GPS, is not detectable by radar detection devices and can expand by connecting with your Bluetooth phone. 

The detection performance of the new Whistler CR97 is comparable to detectors that cost double. In addition to improved performance, the Whistler CR97 is the only detector that is capable of identifying and alerting the photo radar of the FMCW law enforcement agencies used to issue tickets, which are used at higher frequencies throughout the United States. The new Escort MAXCam 360c is the first integrated dashcam with extreme performance radar detection from Escort, providing complete 360-degree coverage with colored directional arrows, as well as an enhanced capability to filter out the majority of the false alarms caused by the anti-collision sensors installed on today's new cars. Escorts TotalShield Technology basically means that it is invisible to radar detectors, devices used by the police (think of VG-2s back in the day) to detect whether or not you have one.
