How We Choose the Best Cobra Radar Detector

When it comes to selecting the top radar detector from Cobra, having the ability to do hands on testing of different models and brands is a great help. And it’s certainly important to keep an eye on the latest models, as the technology behind radar detectors – whether they’re from Cobra or other manufacturers – continues to evolve. One example is the instant-on technology you’ll find in our top pick, the Cobra 7800. It responds instantly when detecting an active radar, which is something other units may struggle to do.

A top Cobra radar detector needs to appeal to a wide variety of users, so we sought out a model in the 7800 with a mid-range price point.

Perhaps the best new technology found in today’s detectors is the ability of the unit to communicate with smartphone apps to find locations of radar traps, mounted speed cameras, and red light cameras. In testing radar detectors during city driving, having the latest information available is invaluable in giving you a higher success rate when it comes to avoiding tickets from radar-happy cops.

Before you purchase and install a detector, understand the laws in the states where you plan to drive the most often.

Don’t Leave the Unit in Plain Sight: Those looking to steal something will gladly grab your radar detector from a parked car. Most units are designed to be removed from the mounting bracket when they’re not in use, so make sure you select one of those designs if you’re concerned about thieves.
