New Uniden R4 Extreme Long-Range Laser/Radar Detector

The R4 by Uniden has a much greater range than the R3. Its Auto Mute Memory feature automatically locks out false alert locations. The R4’s K Band filter on the market signficantly reduces the amount of false alerts from blind spot monitors and K Band sensors in other vehicles. When you need the best information possible and none of the noise Uniden’s R4 Extreme puts you miles ahead.
