The Beltronics STi Magnum provides long range and accuracy without complicating the functions, making it a great entry-level radar detector. The STi does include an Earphone Jack for a standard 3.5 mm mono earphone plug.
The STi is also a great detector for motorcycle riding when you accessorize with the correct motorcycle mount, weather protection (use a child’s shower cap) and external warning device.

The Beltronics STi Magnum is able to detect radar 14 miles on a straight run road due to its design using two antennas.  The three-sensitivity modes are Auto, Auto No X, and Highway.  You will no doubt use the Auto setting more frequently.  The Auto mode turns on the internal filter using digital signal processing.  It will suppress radar that is not from a radar gun.

By removing the X-band from detection, the STi’s Auto No X increases the sensitivity even further, since false alerts are normally generated with the X-band range.  You will get more false alerts in a more dense population region.

Stealth Technology and GPS

Escort Live

Escort Live Help You Communicate With Other Users For Sharing And Receive Threats.

Being the first to use stealth technology, the Beltronics STi Magnum made their detector totally invisible to the Spectre Radar-Detector Detectors (RDDs) putting it at the top of the line.  In today’s marketplace there are only 4 detectors that are able to defeat the Spectre and the Beltronics STi Magnum is one of them.

The STi is not equipped with GPS therefore it does not provide preloaded locations for speed traps, red light and speed cameras.  You cannot block false alerts, potential threats, or receive, and share location information with other users.  You can, however, use the SmartPlug™ to connect with your Smartphone through Bluetooth.  This permits you to use the GPS in your phone’s app to share the task using the Escort Live mobile app.  While it’s not as great as a built-in GPS, it’s better than none and will alert you to non-radar threats such as speed traps and cameras.  The disadvantage is that you will need to subscribe to the Escort Live app.

Specifications and Exclusive Qualities

The STi is an industry leader with its low noise amplifier (LNA) microwave receiver delivering long warnings on all radar bands to include the latest POP (Point of Presence) threats defeating radar detectors.  The case on the STi Magnum is magnesium, as a result its name.  Its tough metal case is matte black to keep it stealthy and it will resist windshield reflections of itself.  The three front-mounted control buttons are red-backlit—another industry first—for easy nighttime operation.

  • TotalShield™ Technology—makes the STi Magnum invisible to RDDs. This feature is exclusive to Beltronics STi Magnum and you will not be seen by existing Spectre and VG2 as well as being undetectable by future threats.
  • Digital Signal Processing (DSP)—the AutoScan™ constantly analyzes all incoming signals. It will discard redundant false alarms providing you with a stabilized performing long-range detector without irritating false alarms.
  • User-friendly Controls and Options—the preset controls by the factory are set for short and/or long trips in the U.S.A. To satisfy your driving style, 9 features are customizable for how you like to drive.
  • Laser Protection-the Next Generation—the many laser sensors in the unit are situated intentionally for continuously searching for signals from laser guns. The superior off-axis protection and maximum range are standard for the STi.
  • Text Display in High Def—the STi is easy to read from any angle with its brightest text display. Select from 3 different indicator modes to suit you.
  • Clear Voice Alerts—with the crisp and clear digital voice alerts you can keep your eyes on the road and hear your information. When purchasing, ask about the Beltronics STi amplified speaker option for exceptional noise areas.
  • AutoMute™ and Muting—automatically reduces the volume level when alerted. Alternatively, press the large front-mounted Mute button on the SmartPlug™ that is included to quiet the audio alert immediately.
  • City Mode Filters—Select from City, City Standard, or City No X for operation.
  • Brightness and Full-dark Modes—with 4 levels of brightness you can choose from Auto that changes the brightness based upon the light in your vehicle or choose the full-dark mode using the on button and alert indicators on the SmartPlug™ for stealth action.
