Cobra XRS 9945 Review



The Cobra XRS 9945 is capable of using GPS like its sibling XRS 9955, but this model requires an optional locator that costs about $120. Test results reported on product review sites note that this detector doesn't pick up the older X band very well, but it can pick up K and KA signals about 30,000 feet away.

The range of the Cobra XRS 9945 (starting at $122, Amazon) is hard to beat. A Cobra XRS 9945 review by experts at Radar Rest reports this model sniffs out radar guns beaming the K and KA bands on a straight-away up to 30,000 feet out, or about 5.7 miles. This model earns hearty thanks from drivers posting reviews on Viewpoints for alerting them in time to slow down, thus avoiding the dreaded speeding ticket. That sensitivity may be a welcome attribute on the highway but it causes lots of false alarms in the city, note several reviews, whose writers aren't really complaining. The solution: Hit the mute button, which eliminates the annoying beeps every time you pass a bank or gas station or shopping strip.

We did note that some users report the unit fails to spot speed traps, especially when police are using the older X band. And one driver grouses in a Cobra XRS 9945 review on Amazon about its design; specifically, the power cord is a bit too short for his car, which means he can't mount the cheap radar detector properly, and the suction cup mounts don't stay stuck to the windshield.

Where to buy

The Cobra XRS 9945 features a color display that uses different colors to send different messages, a dim mode for easier night driving, an eight-point compass that can be helpful in unfamiliar terrain, and a component that signals if the car battery voltage falls below 11.9 volts. It also offers the option of adding a GPS system that can detect red light and speed cameras up ahead. And it boasts the power to shield itself from radar-detector detectors or alert you to one coming up.

Overall, the Cobra XRS 9945 is a decent buy. Reported struggles with the X band shouldn't be enough to dissuade you from this model given its sensitivity to the K and KA bands, which prevail in the radar gun market.
