The Escort Passport Max 360c has built-in Wi-Fi, allowing it to link seamlessly with the Escort Live crowd-sourced ticket-avoidance network.

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.

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.

Like the Pro M, the XP has GPS and adjustable, speed-based alerts. It warns of red light and speed cameras and like other Radensos, has one of the best OLED displays in the business.

The XP turned in surprisingly good scores in recent tests, outpacing others in its class on Ka band, the frequency used by most police. It shares with the Pro M software that detects and ignores BSM radar.

Same as the Pro M and SP, it's covered by a speeding ticket-reimbursement program.

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.
