Design
Mounting the 8500 in our test vehicle was easy and straightforward. A small suction cup bracket slides into the unit's release mechanism and easily attaches to the windshield with light pressure. The unit is housed in a sturdy plastic case that's low profile and compact--although it is larger and heavier than Escort's wireless offering, the Solo S2. The rear of the unit is dominated by a receiver window and there's a rear-facing laser detector window designed to detect laser signals emanating from behind the vehicle.

Features
The 8500 can detect all of the radar bands currently in use in North America for speed detection, including the X, K and Ka bands. The unit also features detection diodes for laser detection, but for the most powerful protection from laser detection, Escort offers the ZR3 laser jamming system, which is plug-and-play compatible with the 8500.
The feature that separates the 8500 from other Escort radar detectors, as well as the entire previous generation of radar detector technologies, is its Pop radar detection capabilities. Pop radar guns, while still relatively rare in police departments, are used to identify speeding vehicles in traffic. They provide little warning as the radar signal idles at a low frequency until it transmits an extremely short, high-frequency burst to "Pop" a target. The 8500 is equipped with a highly sensitive receiving system and a digital signal processor designed to pick up Pop signals from a safe distance. Pop detection is not enabled by default in the 8500, however; users must turn it on in the settings menu. Escort probably chose to disable Pop detection by default because its increased sensitivity also increases false alerts. However, first-time radar detector users might be in for a surprise if they neglect to turn it on.

False alarms are one of the major annoyances of radar detector use. In our tests, the 8500 was surprisingly adept at minimizing false alarms from home garage door systems, as well as home and commercial security systems that commonly operate on X-band radar. The unit's city sensitivity setting decreases sensitivity to X-band sources, while the highway setting does not. We found the unit's powerful "AutoSensitivity" mode the most accurate, however, as it dynamically filtered all types of radar signals and identified which sources were a legitimate threat. We got a few false alarms, but for the most part, annoying chirps from bogus X-band sources were uncommon.
The 8500 has nine built-in customizable settings. In the settings mode, the LCD acts as a menu system that lets users control display brightness, automatic mute, audio tones, and power-on modes. There are also settings for disabling detection of selected bands. We liked the expert mode settings, which allow a user to get a constant picture of the intensity of all the radar bands in the area. The SpecDisplay, which is a feature exclusive to the 8500, displays the actual numeric frequency of the radar signal being received.
For those living in states that prohibit use of a radar detector, the 8500 does include VG-2 radar detector detector protection, which is designed to both alert the driver and shut down the unit's oscillator.
On the Road
We used the 8500 on a 20-mile stretch of busy interstate and were impressed with the low number of false alarms we received. Again, this remarkable level of accuracy is due to the unit's AutoSensitivity feature. While we encountered no police radar, other controlled tests of the 8500's performance have put the reliable range of detection at 2 miles for all bands. Meanwhile, Pop mode tests place the reliable detection range between 500 and 1000 feet.

All-Band Protection
The 8500 X50 provides extreme long-range warning on all radar bands including X, K, superwide Ka, and instant-on POP mode. Multiple front and rear laser sensors provide 360-degree laser protection, including the widest field of view. For the ultimate in laser protection, the Passport 8500 X50 is ZR3 ready.
Escort's patented Digital Signal Processing (DSP) provides extreme radar range with minimal false alarms. Patented Mute and AutoMute circuits keep the Passport 8500 X50 quiet in even the most populated areas.
In addition, the Passport 8500 X50's advanced EZ-Programming lets you customize up to 9 features: Power-On Indication, Power-On Sequence, Signal Strength Meter, AutoMute, Audio Tones, City Mode Sensitivity, Display Brightness, Dark Mode, Radar / Laser Bands.
Brilliant Display
The 8500 features an ultra-bright blue matrix display with 280 LEDs. The device displays three high-resolution meter modes: standard Bar Graph display or ExpertMeter and SpecDisplay for more advanced users. ExpertMeter tracks and displays up to 8 radar signals simultaneously, and SpecDisplay provides actual numeric frequency for any radar signal.
Auto-Sensitivity Mode
Passport's AutoSensitivity mode provides long-range warning, with minimum false alarms. In this mode, Passport�s internal computer continuously analyzes all incoming signals and intelligently adjusts the sensitivity circuits.
You can also select conventional Highway and City modes. When driving in urban areas where annoying X-band intrusion alarms and door openers are common, City mode can be engaged to lower X-band sensitivity and reduce X-band alerts.
One Year Limited Warranty
Get extra peace of mind with Escort's one-year limited warranty. The company also offers a two year extended service plan.
