Ranked #5 in Best Radar Detectors
Uniden R84.5
3 sources2 derived$749.99as of Jul 31The Uniden R8 moves well past the R7 thanks to a dual LNA design that adds roughly 4dB of sensitivity and up to 60% more detection range. Reviewers rated its performance on both K and Ka band highly and found it responds quickly even with filters enabled. Its progressive signal ramp-up tells you more than competitors like the Redline 360c. The redesigned front panel puts the mute button where you'll need to adjust the mount, and it blocks rear laser visibility, which reviewers call practically irrelevant. The R8w variant adds WiFi for automatic updates at $50 more.
