Item Code: XRS9740
Warranty: 2 YEAR

The Cobra XRS-9740 radar detector has extreme advantages over any other radar at this price. It has a digital graphic read-out display that is way better than any detector that is currently on the market at this price point.

The display is generously large, so it will display a wealth of important information such as the battery voltage, digital compass, an icon for highway mode, and much more. On older style displays, there is only room to display 1 or 2 function indicators.

One of the really cool functions of this model is that it has a car battery voltage display. This feature is great if you have a high powered audio or video system in your car, and it is also just generally good to know if your battery voltage is too low or too high, so you can avoid electrical problems. In fact the radar will actually automatically allert the driver if your battery falls below 11.9 volts. Any car battery should be running at approximately 12 volts.

The display is bright, and is easy to read during day or night. Please note you do not need to stare at the display, because it will make a loud beeping noise when it senses a radar or laser signal.

The settings are so easy to set, and extremely user friendly because of the graphic display. On other radar detector models, this is usually one of the biggest complaints.

Another cool feature we noticed on this model, is that the radar detector can detect your speed and automatically mute the radar sound. this is an optional setting.

Most importantly, this radar detector has a 360 degrees coverage and it responds to all types of signals police use to detect the speed of a vehicle. It will detect radar, and laser signals. This model also has an increased range of detection and provides advanced warnings. There is a built in 8 point digital compass, which is an incredible feature.

The other new feature included on this model is selectable voice or beep alerts.
