Overview
Scanning ahead and behind with dual antennas, the Uniden detector reports radar and laser threats with directional arrows and spoken alerts. A built-in GPS adds red light and speed camera warnings, and the OLED screen shows band and signal strength for each threat.
Directional arrows show whether a threat is ahead, behind or to the side, which cuts guesswork on busy highways. Mount, power cord and app details are missing from the listing, and only K and Ka radar bands are named.
Who it's for
Long-distance drivers who cross regions with red light and speed cameras get radar, laser and camera alerts on one screen. Drivers who want recorded video need a dash cam instead.
Pros and cons
- Front and rear detection with arrows
- Voice alerts call out direction
- Built-in GPS camera alerts
- OLED shows band and signal strength
- Mount and power cord not listed
- Only K and Ka bands named
- Power source listing is contradictory
- 1 year warranty only
Performance notes
Dual antennas watch front and rear, and the side with the stronger signal drives the direction arrow and voice callout. Camera alerts come from the built-in GPS rather than signal detection, so they work even when nothing is transmitting. Hills, curves and traffic still shorten detection range for any radar signal.
