Whistler's XTR-555 laser/radar detector boasts total band protection from radar signals, 360-degree laser detection, Whistler's patented VG-2 cloaking technology, and plenty more. A red text display, Whistler's exclusive Twin Alert Periscope, and Real Voice technology all make sure you don't miss a beep.

4.41 x 2.84 x 1.35 inches and just 5.6 ounces.

This unit features Whistler's low-profile "alert periscope" LEDs that flash when the unit alarms.

Red Text Display
The XTR-555's brilliant red text display provides distinct visual confirmation of signals detected, signal strength, and indicates engaged modes of operation.

Integrated Real Voice
When selected, Real Voice provides added information to the detected signal over and above the simple band ID tones. The unit says "X band" when it detects an X band signal. This allows you to keep your eyes on-the-road. Real Voice is also used to articulate Safety Warning System messages and feature selections.

POP Mode Alerts
There are new guns out there that operate just like the instant-on guns of the past but with a very tough new twist--POP mode. This new gun is a normal K and Ka band radar gun detectable by most radar detectors made in the past 30 years until it's in POP mode. When the gun is in POP Mode and activated, a brief burst of energy, less than 1/15 of a second, is transmitted and the vehicle's speed is quickly acquired. A detector without POP Mode detection capability cannot respond to this brief transmission. This one can.

Twin Alert Periscopes
Whistler's Low Profile Alert Periscopes provide an added attention getting visual alert. The two extra LEDs flash on and off when the unit alarms to provide a unique visual alert.

Selectable Total Band Protection
This unit provides complete band coverage of all Laser, Radar (X, K, and Ka bands), VG-2, and Safety Radar bands. You can select which bands to leave on or off based on your detection needs.

360 Degree Protection
Units with 360 protection detect signals from all radar, laser, VG-2 and safety radar systems wherever they come from; front, rear or from the side.

3 City Modes/Highway Mode
Highway mode provides full audio and visual warning of laser/radar systems while maintaining full sensitivity, and is the default setting of Whistler laser/radar detectors. City mode helps reduce the annoyance of automatic door openers and burglar alarm alerts by providing an initial alert (same distance as Highway Mode) then remaining quiet unless the signal strength becomes very strong. When the signal increases the unit will alert briefly to notify you of the change in signal strength.

High Gain Lens
A high gain optical lens provides increased sensitivity and field of view for leading-edge laser detection.

Stay Alert
Whistler's exclusive Stay Alert feature tests your alertness on long trips.

Dim/Dark Mode
Dim/Dark Mode reduces the illumination of the display. reduced. Dim or dark can be engaged during an alert. In Dark Mode, the display goes dark for as long as a signal is being detected and for 20 seconds after, then the display returns to the dimmer setting.

Quiet/Auto Quiet Modes
Pressing QUIET before a signal is detected engages Auto Quiet Mode, which automatically reduces the audio level after the initial warning to a low audio level setting. Pressing QUIET during a radar/laser encounter silences audio alerts, while allowing visual alerts to keep you informed.

Alert Priority
When two or more signals are received at the same time, the alert priority is: Laser, VG-2, Speed Radar, Safety Radar.

Example: If X band is alerting, then suddenly a VG-2 signal is detected, the VG-2 warning will override the X band alert.

Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically shuts off your detector within 3 hours if you forget to turn it off. The timer is reset if the detector is turned off, unplugged or any button is pressed before the 6 hours have expired. The detector will alert you with an audible and visual warning before it shuts off.

Safety Warning System--SWS
This relatively new radar is not for speed detection at all, it is used to keep you informed of highway safety. Transmitters are installed and programmed (for example: in emergency vehicles) to make you aware of possible situations that may require your attention, such as: ambulance vehicles that are moving or stationary, road hazards ahead, road construction delays or detours, etc.

VG-2 Cloaking
The VG-2, also known as a "radar detector detector," is a special receiver used by police to detect signals radiated by a radar detector. Thanks to Whistler's patented VG-2 cloaking technology, your detector will remain invisible to VG-2 detection.

Setting Saver
Setting Saver saves your personalized settings so that when the detector is turned off and then on again, you do not have to re-enter them.
