The Beltronics Pro 300, like his small brother reviewed here, is a sleek, small device that’s easy to install and hide from view. Its build and casing are covered in black, adding to its professional look. It has simple and straightforward buttons that are conveniently located at the top of the device, while the display offers a view of the many radar signals it can detect, plus the signal strength.

Features Overview

Quick Alerts

The Beltronics Pro 300 radar detector is designed for consistent performance under all weather conditions. The POP-mode-alert gives you warning signals within the split of a second, enabling you to switch your speeding vehicle sharply into safe mode.


The signaling system is accurate and sharp. You get ample time to slow down without running into the danger of bumping into a slowing vehicle ahead or getting bumped from a speeding vehicle from the rear. The auto-scan feature can detect multiple types of traffic modes instantly. It saves you the effort to change the settings manually, every time you enter a busy city traffic zone or get into a speeding high-way zone.

360-Degree Detection

The device detects even the weakest of signals from Radar and Laser devices which are placed in non-visible regions off the road. The scanning spreads to almost 360-degrees around your vehicle.

Smart Filtering

The radar detector can clearly distinguish between the radar, laser and safety signals from others, filtering in only the customized frequencies into the main device. This helps you in avoiding confusion by eliminating all possible fake alarms which could distract you from driving.

The device can accurately measure all types of signal strengths emanating from varying distances. The only requirement is that you need to mount the device in the most appropriate position in your vehicle from where it can get undisturbed input. The rest will be taken care of by the system.

If you take a comparative view of Beltronics Pro 300 Vs rx65, you will find that the Beltronics pro has many additional features like:

  1. Voice-alerts.
  2. KA-USA-mode
  3. Ability to pick up the consistently changing frequency and wavelengths of radar and laser signals. This effectively covers many “gaps” left out by the different versions of the RX-model.
