Choosing a detector for Alabama roads
Look for Ka-band sensitivity (the band most state patrols use), 360-degree coverage so instant-on radar behind you is caught, and a city filter to suppress false alerts in urban traffic. The McFlash 360 covers all three and installs without tools, which matters if you move it between vehicles.
