Common questions

Questions before you buy

What is a good radar detector for a car?

A good fit depends on your route, preferred alerts and local rules. Compare supported bands, filtering controls, GPS features, display and mounting before choosing.

What is the best police radar detector?

There is no single best model for every driver. The Uniden R8, Escort Redline 360c and Uniden R7 document directional features, while the Cobra RAD 700i emphasizes app-linked functions.

Can a radar detector detect every police speed measurement?

No. Detectors only alert to supported signals they receive, and some enforcement methods do not transmit a signal a consumer detector can usefully detect.

Are radar detectors legal in my state?

Rules vary by state, vehicle class and jurisdiction. Verify current law where you drive before installing or using one.
