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.*
Features
Definitions:
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-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.
