  • Features VG-2 detection
  • Comes with power cord, windshield bracket kit, and user guide

Cons

  • Volume of alerts can be too weak, especially for motorcycle use
  • Gives alert for blind spot sensors, hence, more false alerts

Overview

Whistler XTR-145 Laser Radar Detector is a much affordable device for what it offers: mainly, 360 degrees of protection from laser and radar (X, K, and Ka) bands. It can also detect VG-2 and alert the user through its clear and bright icon display. Other indicators in the display include city mode, radar band identification, power, and signal strength.

The addition of VG-2 Cloaking makes this device an even more special detector to use, especially when it can be invisible to the known radar detector detector, VG-2. This way, police enforcers wouldn’t detect that there is a radar detector installed in your vehicle, and you can drive away unnoticed.

This device also allows options among different mode of driving—you can pick Highway mode for full experience of visual and audio warning system of this Whistler device or you can pick among its 3 city modes. While on City Mode, annoying alerts and false threats can be minimized as these modes reduce the sensitivity of the detector to burglar alarms and automatic door openers.

Another thing we laud this model for is its ability to discern among all alerts, called “Alert Priority”. This ensures that when two or more signal are received by the detector at the same time, it would know what to alert the user first: Laser, then VG-2, then Speed Radar, and lastly, Safety Radar.

While there can be issues when it comes to the loudness of the audio alerts when used when the windows are rolled down or when driving a motorcycle, it does pretty well when you’re driving normally with all windows closed. With its price point, the loudness issue can be pretty much easily compensated with its other features.
