In honor of our old friend Brock Yates, the impresario of the legendary Cannonball Run, we use a system of one to five cannonballs to rank the detectors.

Bel Pro RX-75



Pros: All the excellent capabilities of the test-winning Bel Pro RX-65, but configured to be concealed in your vehicle. Unlike a one piece, portable unit that is typically on the windshield, this unit is separated into two pieces. The reception portion is mounted under hood, typically right behind the grille of your vehicle. A cable runs from this portion thru the engine compartment, then thru the firewall into the passenger compartment, where a small control panel with your display and buttons can be located down low (typically the bottom edge of the dash or in the console). If you frequently drive in areas like Virginia where detector possession is illegal, this degree of concealment can be quite useful. Also, if you frequently park in areas where radar detector theft is rampant, it’s useful to hide your stuff from thieves, too. An upgrade version is available (RX-75 Plus) which adds a laser jamming capability. If you drive in areas where laser is common, a definite advantage.

Cons: This type of configuration obviously means that you give up portability. If you need to frequently move your unit between a couple of your cars, then this may not be a good choice. If you fly frequently and need to pop your unit into a rental car, then again not a good choice. Additionally, this type of configuration is inherently more expensive than a comparable portable detector. The underhood environment is harsh, and all the components, wiring harnesses, plugs and connectors have to be waterproof and able to handle extreme temperatures.

Bottom Line: If you need concealment from cops or thieves, an excellent choice. Quite simply the best built-in detector on the market.
