![]() ![]() This is especially beneficial when using a single detector between multiple vehicles. The cordless option is the best route to go if you want the freedom to move the detector around. As long as your car has a 12V outlet, you can keep the radar detector plugged in and mounted to the dash so it naturally works without needing a recharge. In most cases, you can choose between corded and cordless options.Ĭorded radar detectors are a common option for anyone looking for an easy-to-install, easy-to-use solution for their vehicle. The type of detector largely determines the type of power supply it will have. Like any electronic device, radar detectors must have a constant supply of power in order to work. Remote radar detectors, on the other hand, mount behind the grille of the car to remain out of sight in a place where there is no glass in the way. ![]() Commonly, radar detectors mount onto the dashboard where there are fewer obstacles between it and incoming radar signals. The placement of the radar detector can also affect its sensitivity. In general, a detector with 10 dB is good enough for everyday use against most radar guns. Common on higher-end detectors, a high sensitivity level extends the range of the detector, giving you more warning ahead of time before reaching the radar gun. Radar detectors with a higher sensitivity (usually measured in decibels or dB) can pick up weaker signals. Still, like a microphone, the radar detector's sensitivity will determine how effective it is at picking up signals long before the gun detects the car. Instead of sound waves, however, radar detectors can pick up the different radio waves radar guns use. In some ways, a radar detector is nothing more than a microphone picking up the "noise" radar guns emit to determine speed. These detectors are usually designed for people living in states where such radar detectors are illegal and police use radar detector detectors in addition to the radar guns. For example, some radar detectors include VG-2 Alert and Non-Detection features that mask the use of the detector. If the gun is always active during use, there is enough signal to pick up before the car will start to bounce it.Īdditional detection capabilities are also possible. Most radar detectors listen for X, K, Ka, or laser bands before getting close to the gun itself. By measuring the difference between the original frequency and the new one, the gun can automatically determine the speed of the car. When a car passes through the gun's sights, its body bounces a portion of that signal back while changing the frequency. Ideally, this detection will happen long before a radar gun has your vehicle in its sights.Ī radar gun usually works by broadcasting a continuous, consistent signal. The main purpose of a radar detector is to actually detect the signals radar guns put out when measuring the speed of a car. Key considerations Frequency detection range Many police forces use aircraft-based or specialized speed detectors that don't rely on the radio or laser bands typical radar detectors pick up. Radar detectors have limitations when it comes to speed enforcement protection. Our list of top radar detector models will also give you a good place to start to find the right one for your needs. We've included important information, considerations, and features you should know to make the best decision. Newer detectors, however, have expanded to keep up with evolving radar gun technology, so you can find different models with greater capabilities as well.Īs you start your search for the best radar detector, check out this handy guide for help. Regular detectors can pick up the most common police gun frequencies like X and K. When buying a new radar detector, a large range of detection capabilities should be high on the priority list. Cobra makes some of the best radar detectors available. A common detector monitors the area surrounding a car, picking up the radar or laser signals guns use to bounce off of moving vehicles to determine speed. Buying guide for best cobra radar detectorsįor drivers who want to stay away from speed traps, a radar detector is a common choice to pick up the signal of a radar gun. ![]()
