Cobra SPX 7800BT Radar Detector – $229.95
You drive a vehicle, right? Of course you do. There's nothing worse than getting a speeding ticket, it's expensive and inconvenient and it's probably the reason that you use Waze. Well, Waze will only get you so far, and it's no replacement for a real, hardware-based detector.
The Cobra SPX 7800BT ($229.95) is the smallest and most powerful radar detector ever brought to market, it's about half the size of other radar detectors. It comes with AURA speed and red light camera notifications, verified user-reported alerts of upcoming live police locations and other real-time traffic threat information via a paired smartphone.
Pro tip: Buck up for the hardwire cord ($10) and have a pro connect it to your vehicle's fuse box. I installed my detector under the sun visor (next to the rear-view mirror) so I permanent power and don't have a cable draped across my dash.
Honorable mention: The iRadar ATOM (iRAD 900) is smaller and less expensive because it doesn't have the slick OLED display in its big brother. Pick one up for $199.
