There’s a bunch of radar detectors on the market, some good and some bad, expensive or cheap, simple or fancy. What’s the difference?
The most basic ones will beep when they detect radar, but typically the range is poor and you’ll get a ton of false alerts so I recommend avoiding the super cheap ones (under $150 or so).
Better detectors offer longer range (important for tougher situations) and better false alert filtering.
Then some high end detectors add features like directional arrows, GPS, Bluetooth with app integration, photo radar detection, and more.
