Product Features

Number of Modes
This number indicates how many modes the radar detector can be set at. Most detectors will include a city and highway mode. More advanced radar/laser detectors will offer more modes to suit your needs.
Dark Mode
Dark mode is a brightness option. Unless there is an alert, the unit will be completely dark.
Voice Alerts
The feature designates if the unit uses voice alerts. Voice alerts will audibly alert the driver of various warnings.
Auto Mute
The auto mute function will conveniently mute the alert tone when the alert lasts for an extended period of time. This is for the drivers convenience during extended encounters.
Auto Shut Off
A convenient feature that turns off the unit when the ignition is turned off.

Product Specifications

Radar Display
The type of display that the radar detector has.

LED Displays: Tells the driver what he or she needs to know through a bright LED display.

LED Icon Indicators: Tells the driver what he or she needs to know by illuminating icons and symbols.

Text Display: Tells the driver what he or she needs to know by illuminating text on the display.

LED Display
Signal Strength Meter
This feature means that the unit displays that strength of the received signal.
Brightness Control
If the brightness of the unit can be conveniently adjusted and controlled, it will be listed here.
Turn-on/off Select Bands
Many radar detectors can detect many different bands of signal. This feature designates if the user can select what bands he or she has on or off.
Unit Mounting
Different radar detector are attached to the vehicle in different ways. The most common is for it to be suction-cupped to the windshield. This allows the unit to be moved from one vehicle to another with ease. Another mounting option is called remote-mounting. A remote mount unit is directly installed into your vehicle.

Other ways to mount your radar detector include Velcro and adhesive.

Power Source
The power source is the method in which the unit receives power. Some units will be powered by batteries, while others will need to be plugged in to an AC or DC power source.
Integrated 12V DC
Travel Case Included
If a protective travel case is included, it will be listed here.


Number of Detected Bands
This number indicates the number of bands the radar/laser detector protects against. The term band includes different radars, lasers, and safety signals, among others. The higher the number, the greater the protection.
X Band
X Band is a frequency used for detecting speed from a police radar.
K Band
K Band is the most popular radar frequency band that is used today. It is able to detect speeds from a stand still location, or from a moving vehicle
Ka Band
Ka Band operates within the frequencies 26.5-40 GHz. This is the newest introduced radar band and it is becoming more and more popular. It rarely has a false alert.
Ku Band
Ku band ranges from 12-18 GHz when used in radar applications.
This feature specifies if the unit will detect lasers.
VG-2 Immunity
The VG-2 detects radar detectors. Radar detectors with VG-2 immunity will be immune to the VG-2 radar and alert the driver when they are under such surveillance.
Pop Alert
Some radar guns operate in a POP mode so they can get a speed reading of a target vehicle extremely fast, resulting in most radar detectors not being able to consistently signal an alert. There are very few radar guns in service in the U.S. capable of POP mode operation. If your radar detector is Pop Alert capable, you may notice an increase in Ka-band false alerts when POP mode radar detection is switched on.

Best defence against a laser ticket.

April 7, 2010

I now own 6 of the RX75 Pro Pluses, every vehicle I own has one, On three of them I was able to install myself but on the three sports cars I had to get professional installation, could not get under vehicle to to feed wiring inside of vehicle and to position components under the dash. Average installation cost was 180 dollars canadian. These units give laser blocking technology not available with most other detectors. They really do work. These units give several miles of advanced warning a radar presence. Driving in metro areas is a little distracting with numerous items setting off false signals, in Canada a lots of traffic lights are controlled by radar signals, shopping center automatic doors use a radar frequency signal. But where it counts on most roads this product does it job. The Pro Pluses come with a very good remote speaker for audible alerts. A very complete system !

BEL pro rx75 plus!

December 28, 2009

My buddy has this radar, and I'm about to buy it too. I have to say, it works great. It detects any radar laser from a great distance. My favorite things about the radar are the concealed look, and the radar jamming. My friend who has this radar got pulled over for doing 90 in a 50, gave his license/reg. , and when the cop came back to the car he said "You are lucky your radar jammed my laser, you were definitely speeding." Gives him his license/reg. back, and Says "Have a Nice day" and walks away. This radar saved his a$$!
