Final Verdict


The Passport 8500 X50 Radar Detector is a good choice for some, but many drivers will dislike that the company no longer makes it and no longer offers support for it.

If you need something basic and affordable that you can use when taking road trips with friends and family or driving for work though, you can pick up one of these models for a fraction of what other radar detectors cost.

The 8500 X50 has a microprocessor that you can actually reprogram to search for new types of bands, though it does an impressive job of searching for several different band types on its own.

This radar detector also has several built-in modes for highway driving and driving through the city. Depending on what you want in a radar detector and how often you drive, the Passport 8500 X50 might be the best one for your car.
