DESC: Unlike many ordinary radar detectors, the STEEL EYE 3100 powerful detection system contains two separate sensors, so it can detect all forms of radar (X- band, K and Ka band) and laser. It also detects POP radar guns, to give you that critical extra second or two of reaction time. PNI The Steel Eye 3100 warns you with both audio and visual alerts, and mounts in seconds without wires, screws or cords!
