These include the most notorious of radar signals such as the X Band, K Band, Ka Superwide, Ku Band, VG-2, Spectre I and Spectre IV+.

Additionally, the 6 laser signals that the XRS9470 offers detection for the LTI 20-20, Ultra Lyte, ProLaser, ProLaser III, Stalker LIDAR and Speed laser. Whilst the safety signal detectable is the Safety Alert.

IntelliMute Pro – This feature actually automatically shuts down and makes your radar undetectable by radar speed detectors currently available on the market.

DigiView Data Display - This feature offers users a display that provides easy recognition of bands detected by using its easily recognizable text display that is digital. Additionally, this features a meter that gives a 5 level digital signal strength showing your relative proximity to the target.

The Whistler XTR-130 is a fully featured affordable radar detector. The XTR-130 does not only offer full protection from radar signals but it also offers a complete 360 degree detection of laser detection. The XTR-130 comes equipped with the Whistler patented VG-2 cloaking technology, amongst numerous other features. The many features of the Whistler XTR-130 include:


  • 3 City Modes/Highway Mode - The Highway mode offers you complete visual and audio warning of laser and radar systems while maintaining full sensitivity. This default setting helps the driver to reduce those annoying burglar alarms and automatic door openers that are usually found in cities. This provides an initial alert, after which it remains quiet only returning when the strength of the signal received becomes very strong. When this happens the unit will then briefly alert you to notify you of the change in signal strength. Additionally, the device offers three filter modes that reduce false alerts caused from other radar detectors.

  • Quiet & Auto Quiet Modes – The XTR-130 also comes with this feature that enables the device to go quiet when pressed before a signal is detected. This feature automatically reduces the audio level after the initial warning, to a lower audio setting level. Enabling this mode during a radar/laser encounter not only silences the audio alerts, but it also permits the driver its visual alerts that keep you informed.

  • VG-2 Detection Mode – This feature enables the device provides the device with the ability to go undetected from this special receiver used by police that detects the radiation emitted from an incoming car that maybe using a radio detector. Patented by Whistler, this cloaking device is a really welcomed feature.

  • Alert Priority – This feature actually prioritizes the signals received when picking up more than one signals at a time. Computer programmed by order of Laser, VG-2, Speed Radar, Safety Radar; the device will switch to VG-2 signal suddenly, even after it has detected an x band alert, hence the VG-2 warning will override the X band alert.

  • Vehicle Battery Saver Mode – This mode automatically shuts down the vehicle after 3 hours of use. This feature assumes that you have forgotten to turn off the device after stopping and as such promptly acts in this manner. Additionally, the timer on the device is reset whenever the detector is turned off, unplugged or if any of the buttons is pressed before the 6 hours have expired. Of importance is also the fact that the device will alert you with an audible as well as a visual warning before it shuts off.

Uniden LRD450 Laser Radar Detector

The LRD450 is a long range radar detector that detects emissions from radar guns and then gives off audio sounds alerting the driver of such signals. Capable of determining which band range the signal is from the LRD450 offers protection against such band ranges. Priced at a medium price point, the  Unilad LRD450 is an effective device that provides the basic functions needed to avoid having to pay ticket fines. The display is able to show which band range the signal is from whether (X K Ka or L); as well as showing the frequency strength represented by numbers 1-5 depending on the strength of the signal. The device is also able to show any particular specific code, if such a code is available. Additionally the LRD50 uses two different modes for highway or city use with the voice announce feature relaying to you the unit status as this changes.


  • Exceptional Range
  • 2 City Filter modes
  • For the price this is actually a bargain

With the pro-78SE you actually get desired piece of mind knowing that you will be saving money by drastically reducing or eliminating the amounts you will have to send on traffic tickets and traffic fines. Some of the many features for this include

More In-Detailed

Blue Text Display – This feature offers you text displays in a clear way. In this display you are able to get confirmation of the signals detected, signal strength as well as the engaged modes of operation.

Filter Mode – This feature essentially protects against false alarm. So the filter mode basically checks the signal’s it receive and then verifies if it is legitimate police radar or a false alert from another detector. The whisper also has a 3 city mode/highway mode. What this feature does is that it allows the users to differentiate and set the radar and thus reduce the annoyance of automatic door openers and burglar alarm alerts by providing when driving through urban areas.

Auto Dim Mode – This feature is one of convenience as it automatically switches the contrast of the text display based on the lighting quality that is around you at any given moment.

Real voice alerts – This feature allows the user to keep their eyes on the road whilst driving. What this feature will do for you is that it actually sounds off a real voice alert whenever it identifies a band, is issuing safety warning system messages, or to select a particular feature. Again this is added convenience.

Vehicle Battery Saver Mode – I like this feature as the system actually automatically shuts off within three hours as it might be that you forgot to turn off the system.
