Not to restart an old debate, but if you're looking for information about radar detectors, I suggest you follow this link to the February 2002 edition of
Car and Driver magazine for its article on
The Great Detector Test. If you want a preview, C&D rated the detectors in the following order:
- Valentine One (not surprisingly, because it has won every C&D evaluation)
- Passport 8500
- Bel 980
- Cobra XR-1050
- Whistler 1780
- Uniden LRD 987
