Total Band Protection
Provides complete band coverage of all Laser, Radar, VG-2, and Safety Radar bands.

Icon Display
The XTR-140 display offers easy-to-read icons to indicate power, city mode, radar band identification, and signal strength.

Twin Alert Periscope
Whistler’s exclusive Twin Alert Periscope provides an added attention-getting visual alert, with two extra LEDs flashing on and off when the unit alarms.

Three City Modes and Highway Mode
Highway mode provides full audio and visual warning of laser/radar systems while maintaining full sensitivity. Highway mode is the default setting of all Whistler’s 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.

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 three hours if you forget to turn it off. The timer is reset if the detector is turned off or unplugged, or any button is pressed before the six hours have expired. The detector will alert you with an audible and visual warning before it shuts off.

Patented VG-2 Cloaking Technology
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. The XTR-330 alerts you its presence, and thanks to Whistler’s patented VG-2 cloaking technology, it also provides undetectability.

    Amazing cost/performance detector I was extremely skeptical about the performance of a $40 detector, but after a few recent road trips, I am convinced this is actually a well functioning product. Although it does not have exceptional filtering ability for false signals, it can still give you enough X/K/Ka warning for you to slow down in time.The two blue LED’s are a great innovation, because you can easily see them out of the corner of your eye. This is extremely useful when your radio drowns out the audible…

    buy it i purchased the xtr 140 and it has been great so far, from what ive read the 330 has voice alerts and thats the only main difference. higher end radars have alot more features (compass, volt meter, aarows, pop detection etc) but none of that matters to me, i just wanted a radar detector that works. usually i find myself drifting 12 or so mph over the posted limit in the city and it gives me plenty of time to stop. besides a blip of ka when i pass a walgreens or cvs (if you are pointed at the…

    Great buy! Nice quality. No nonsense.Picks up some stray X from industrial parks or commercial buildings occasionally in Highway mode if buildings are adjacent to interstate, BUT these signals easily discerned giving only one bar on strength meter, and a couple warning only chirps.However, first night out, I had my unit reach three bars, light up the entire display like a Christmas tree, blip the periscopes constantly, basically seemed like the thing was going to implode…
