Number of Detected Bands
This number indicates the number of bands the radar/laser detector protects against. The term band includes different radars, lasers, and safety signals, among others. The higher the number, the greater the protection.
X Band
X Band is a frequency used for detecting speed from a police radar.
K Band
K Band is the most popular radar frequency band that is used today. It is able to detect speeds from a stand still location, or from a moving vehicle
Ka Band
Ka Band operates within the frequencies 26.5-40 GHz. This is the newest introduced radar band and it is becoming more and more popular. It rarely has a false alert.
Ku Band
Ku band ranges from 12-18 GHz when used in radar applications.
This feature specifies if the unit will detect lasers.
VG-2 Immunity
The VG-2 detects radar detectors. Radar detectors with VG-2 immunity will be immune to the VG-2 radar and alert the driver when they are under such surveillance.
Pop Alert
Some radar guns operate in a POP mode so they can get a speed reading of a target vehicle extremely fast, resulting in most radar detectors not being able to consistently signal an alert. There are very few radar guns in service in the U.S. capable of POP mode operation. If your radar detector is Pop Alert capable, you may notice an increase in Ka-band false alerts when POP mode radar detection is switched on.
