The Beltronics Pro 100 Radar Detector provides six times the sensitivity of any imported radar detector, including the latest POP mode threat. Optimized for all U.S. radar and laser guns, its lightning fast microprocessor delivers alerts in 500 milliseconds or less. Preset at the factory, the Beltronics Pro 100 Radar Detector is optimized for driving in the United States. However, you can also customize it to meet your specific driving style. Multiple user-selectable options make it simple to change. Multiple sensitivity modes and unique TSR (traffic sensor rejection) help the Pro 100 filter out false alarms. Plus the AutoMute feature reduces the alert volume automatically so you can stay informed without needing to press a mute button. Pro 100's ultra-bright LED matrix display keeps you fully informed. Four levels of brightness, including full-dark mode for discreet night travel, is standard.
