PRO100 Quick Facts

Let's get to the point, the PRO 100 has plenty of great things to talk about but here are the quick facts.
  • 360° protection from all radar bands and laser
  • 280 LED Alphanumeric Display
  • Bar Graph displays detected band and signal strength
  • New technology to reduce false alerts
    • Digital Signal Processing
    • Traffic Signal Rejection (TSR) filters out erroneous X-band and K-band signals caused by traffic flow monitoring systems
  • Voice alerts keep you focused on the road
  • Adjustable brightness levels
  • POP detection
  • Complete VG-2 immunity
  • 6 times more sensitive than imported radar detectors
    • Delivers alerts in 500 milliseconds or less
  • Preset from the factory but there's plenty to customize so keep reading!

Say Goodbye To False Alerts!

False alerts are lame. Almost as lame as a speeding ticket but not quite. But still lame, so that's why Beltronics souped up the tech on the PRO100. Their Traffic Sensor Rejection (TSR) eliminates false alerts from X and K-bands from traffic monitoring systems and door sensors in the area and adjustable City/Highway mode lets you set the sensitivity for your driving area.

  • Adjustable City/Highway Mode
  • Selectable Bands allow you to shut off specific bands
    • Some bands like the X-band aren't used in certain areas for radar enforcement - Turn off the band if it's not needed so you don't get alerted

Crystal Clear Display

The PRO 100 has a ultra bright high definition display that can be easily read at any angle. The bar graph will display the detected band and relative signal strength so you have an idea of where the radar is coming from. And for nighttime driving, you have multiple brightness levels to adjust including a full dark mode for a more discreet driving experience.

  • 280 LED alphanumeric display
  • Bar graph displays detected band and signal strength
  • 3 adjustable brightness levels plus Dark mode

Friendly Voice Alerts Keeps Your Eyes On The Road

Who doesn't like to have a friendly person to chat with on the road? Well, the PRO 100 can't have an actual conversation with you but it'll talk at you and provide you with crisp voice alerts so you can keep your eyes on what matters, which of course would be the road. And in case the PRO 100 is getting a little too chatty, Beltronics patented AutoMute circuitry will reduce the volume level on long encounters.

  • Keep your eyes on the road
  • AutoMute reduces volume level on long encounters

Customize To Your Heart's Desire

Some people just want to pop it in right out of the box which you are perfectly able to do. Others like to tweak around with things a bit. Which you can also do. The PRO100 is ready to go right out of the box or you can set it up just how you like it. The PRO100 wont judge you if you want to change things up a bit.

Product Features

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.

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.

Suction cups
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.
12V DC Car Adapter
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.
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.
