Cobra XRS9770 Review

Essentially the Cobra XRS9770 is a device which detects signals from radar and laser guns in the area. It then provides you with a warning. There are several uses for this, and everyone could use it for different things. Not only will it alert you to the presence of radar / laser guns, it will also tell you the type of band. It alerts you of threats well in advance so you have plenty of time to make a decision.

Here are some specifications:

  • 7 radar signal detection, 6 laser signal detection, and two emergency safety warning system detection.
  • VG2 or Spectre I/IV alert
  • DigiView display with digital text or voice alert function.
  • Can tell the device if you’re in a city or on the highway which reduces false readings.
  • Digital voice
  • 360° protection
  • Completely undetectable
  • Provides a direction heading
  • Eight point e-compass included too.

The system has great range. It can easy detect from miles away. It also is very user friendly- you can get up and running in no time. The display is easy to read and the electronic voice easy to hear.

However there will occasionally be a false alert. The problem is, you never know when something is a false alert or not. There could easily be a radar or laser gun in the area. Just because you don’t see it doesn’t mean it’s not there. So false alerts are usually unverified. It’s better to be over sensitive than the other way around!

The false signal rejection does work pretty well. In all honesty even the more expensive devices will have problems with false signals.

It also looks pretty good and fits in well anywhere. The suction is good so it never slides around. Overall it’s a great device for the money. Pretty good value. Think of it as an investment! You’ll get less tickets.
