The Cobra ESD-9870 is an 11 band™ radar detector providing extended detection range over other Cobra models. It provides alerts announced in plain English by a real human voice with the Voice Alert feature, and also includes an 8 point digital compass. The ESD-9870 radar detector is also equipped with an alpha numeric display, which allows for far more detailed detection messages and a more complex signal strength indicator. The intuitive IntelliMute™ feature is also included, and will automatically mute the detector based on your speed.

The Cobra ESD 9870 responds to all types of radar currently in use by police, and provides 360 degree detection of all types of laser guns. The ESD-9870 also provides detailed messages from Cobra's exclusive Safety Alert® and Strobe Alert warning systems. The Cobra ESD-9870 is immune to the VG-2 detector, and provides alerts when VG-2 is in use. Please note that Cobra claims that this unit is immune to the Spectre "detector detector," but tests have shown that the 9870 is not immune.

Cobra's Strobe Alert will alert motorists to over 50,000 emergency vehicles equipped with strobe transmitters that activate red lights at traffic intersections in emergency high speed situations. Call your local Fire/Police department for your area coverage.

The Cobra ESD-9870 was listed as a top performer in each of the following categories during Speed Measurement Laboratories Annual Detector Test 2003:

• Best At Detecting POP Modes
