It Doesn't Take A Genius...

Beltronics PRO300 Is A Smart Idea

...To know why a radar detector is a good idea. It's a pretty simple concept once you boil it down.

Speeding tickets = time + money

Time and money spent on anything but things you actually want to be doing is bad. Simple right? Unless you actually want a speeding ticket, in which case you can go ahead and skip this awesome Beltronics PRO300 radar detector. But if you're like the rest of us and don't want to spend your hard earned cash on speeding tickets which usually cost over $300 a pop, and you don't want to spend your valuable time in traffic school, then you probably want to get yourself a radar detector. These handy little devices pay for themselves after only a couple saves which is what is referred to as a smart investment and we want to be smart with things like money right? You don't have to come up with the theory of relativity to be a smart person and know that protecting yourself with a radar/laser detector just makes sense.

PRO300 Features

A Mind Blowing Number of Features

In life, false alerts can be terrifying. Nobody likes them. And nobody hates them more than Beltronics which is why they put so much cool technology into the PRO300 to eliminate false alerts. When the alerts go off on the PRO300 you'll know they're real and not just some traffic sensor making your radar detector go haywire.

  • All new AutoScan™ technology provides long range warning and intelligently reduces false alerts
  • Traffic Signal Rejection (TSR) eliminates alerts from X-band and K-band traffic flow sensors
  • Select between AutoScan™, Highway and City modes
  • 3 City Mode filters to eliminate false alerts from X-bands
  • 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
  • Compatible with Escort Live! to receive information about threats from other Beltronics and Escort radar detector users
  • Total Tracking Laser™ circuitry and Dual Port Laser Lens are always searching for laser guns to provide superior range and excellent off axis performance
  • The PRO300 can decode Safety Warning System messages to warn you of dangers on the road

PRO300 LED Display

Crystal Clear Display

The PRO 300 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
  • Exclusive Threat Display shows multiple radar signals along with a strength meter
  • Tech Display shows the exact numeric frequency of the radar being received
  • 4 adjustable brightness levels plus Dark mode

PRO 300 Voice Alerts

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 PRO300 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 300 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

PRO300 Programmable Features

It Just Makes Sense

The PRO300 is ready to go out of the box but it has tons of features to play around with and adjust so you can get the perfect customized protection for your personal driving needs. At the end of the day, investing in a radar detector is just a good idea that can save you some serious cash and headache. This guy over here would pat you on the back and say, "You've made a wise choice my friend."

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.
