Ranger EZ Ranging Police Traffic Radar By MPH (Contact Us for Special Pricing)


Ranger® EZ is the only ranging directional traffic radar on the market. Using MPH's unique Advanced Target Identification™ technology, the RANGER® EZ confirms your visual traffic observations by accurately identifying the strongest target, the fastest target, target directions, target DISTANCES, and targets in opposite and same-direction traffic.

Ranger® EZ also includes SafetyZone™, MPH's officer safety alert mechanism. SafetyZone™ activates an audible warning to alert officers to potentially life-threatening high-speed vehicles approaching from behind their patrol vehicle when the officer is standing on or near the roadway. The loud, distinctive alert signal will trigger whenever an approaching vehicle exceeds the speed and distance thresholds preset by the officer.*

  • Stationary Mode: A radar mode that accurately measures speeds while the patrol vehicle is not moving.
  • Opposite Direction Moving: A radar mode that accurately measures the speeds of vehicles moving in the direction that is opposite the direction the patrol vehicle is traveling.
  • Fastest Vehicle Mode: A radar mode that accurately measures the speed of the fastest vehicle inside the radar beam.
  • Same Direction Mode: A radar mode that accurately measures the speeds of vehicles moving in the same direction as the patrol vehicle.
  • Separable Display: Describes a radar where the display unit can be detached from the radar´s processing unit and mounted separately in the vehicle.
  • Wireless Remote: Describes a radar that is controlled with a cordless remote control rather than with a corded control. Most units with wireless remote controls can also be supplied with a wired remote control.
  • POP Mode: A method for measuring speeds while simultaneously defeating radar detectors. Click here for more information.
  • Distance Ranging: Describes a radar where the display unit can detect and display the distances of the targets being watched.
  • Direction Sensing: A class of radar devices that can measure a vehicle´s direction of travel as well as its speed. Direction sensing allows Automatic Same Direction calculations as well as directional discrimination in stationary mode.
  • Battery Powered: Describes a radar that is powered by an integral, rechargeable battery pack.

SafetyZone - Rear Alert Technology

How does SafetyZone work?

When an officer makes a traffic stop, he can press a button to activate SafetyZone. Ranger then activates its rear antenna and alerts the officer to the presence of any vehicle traveling faster than a pre-determined speed, within a user-determined distance of the patrol vehicle.* (The officer can set the speed and distance to match his patrol situation.)

This alert is sounded in the cabin and broadcast to the officer outside of the vehicle. The external alert can use the vehicle's horn or a dedicated siren and/or light.

SafetyZone can give the officer the opportunity to move to safety and avoid dangerous vehicles. SafetyZone can save lives. See the chart below for examples of how much warning Safety Zone can give you:

Vehicle Distance in Yards
100 Yds 200 Yds 300 Yds 400 Yds

50 mph 4.1 sec 8.2 sec 12.3 sec 16.4 sec
60 mph 3.4 sec 6.8 sec 10.2 sec 13.6 sec
70 mph 2.9 sec 5.8 sec 8.7 sec 11.6 sec
80 mph 2.6 sec 5.2 sec 7.8 sec 10.4 sec
90 mph 2.3 sec 4.6 sec 6.9 sec 9.2 sec
Why hasn´t anything like Safety Zone been offered before now?

Distance-measuring is crucial to making SafetyZone reliable. Before Ranger, no one had developed a ranging radar for law enforcement use.

Traditional radars can only distinguish vehicles by speed or signal strength. Signal strength is a factor of both distance and the size of the vehicle, with larger vehicles giving a much larger signal strength.

In order to alert the officer to small cars close to him, a traditional radar would also overreact by alerting him to large trucks that could be over 3/4 mi. away. Officers would soon lose confidence in the alert if gave many false alarms.

Ranger´s distance information minimizes the number of false alarms of the system by filtering out the signals from large vehicles that are far from the patrol vehicle, and focusing on the speeders who are close to the patrol vehicle and are real threats to the officer´s safety.
