The Escort Redline 360c is the only detector with three antennas, two pointing foward, the third toward the rear. The two in front are for maximum range; the rear antenna allows its arrows to tell where the danger lies.

Bluetooth links to the Escort Live app, the real-time, crowd-sourced ticket-avoidance network.

The Escort Redline 360c uses Wi-Fi to update itself wirelessly, same with its red light camera database.

The Escort Passport Max 360c has built-in Wi-Fi, allowing it to link seamlessly with Escort Live.

It has a rear radar antenna with arrows that point toward a threat. This removes the guesswork about which direction to scan for trouble.

Like other upscale Escorts the Max 360c has Auto Learn—drive past a nuisance signal a few times and next time you go by, it recognizes the door-opener radar and remains silent.

The Escort Redline EX replaces the Redline, our long-range champ. Like its forebear, it has dual forward-facing radar antennae to maximize range.

It also has built-in Bluetooth, allowing instant access to the Escort Live app.

The Redline EX has GPS along with Auto Learn to limit false alerts. Firmware dials back sensitivity automatically at low speeds, further reducing false alerts.

The Escort iXc succeeds the Passport iX and differs by having built-in Wi-Fi. This enables it to use a vehicle's Wi-Fi to connect to the Escort Live app.

Wi-Fi also allows users to wirelessly upload updates of its red light camera database, keeping it current. Same for firmware updates—no obsolescence.

The iXc is the lowest-priced GPS-enabled Escort with features similar to the Max 360c's, save for the rear antenna and arrows.

Radenso's range-topping model has shown impressive performance in our tests, routinely outpacing far pricier models. It has GPS to lock out false alerts and warn of red light cameras.

The Pro M allows users to vary the onset of audible alerts, based on speed, further reducing noise.

The smallest detector on the market, like other Radensos it's covered by a speeding ticket-rebate program.

The Max 3 is Escort's entry-level model with GPS and Bluetooth. Like other upscale Escorts it has AutoLearn that automatically locks out non-police radar as you drive.

Sensitivity adjusts according to your speed, keeping a lid on false alerts.

Bluetooth links with Escort Live, providing early warning of speed traps and roaming police vehicles.

Its software and IVT filter can be updated, preventing obsolesence.

The Escort Passport X80 is a stripped-down model whose primary virtue is a low price.

The X80 lacks GPS, making it more prone to false alarms. It uses the corporate OLED display which is colorful but low in contrast.

The X80 is relatively short on features, although performance is good. It's also the least expensive Escort in the lineup.
