Protect yourself with the convenient BEL 946 cordless radar detector from BEL Technologies! The BEL 946 offers superb protection from X, K, and Ka bands of police radar. BEL's Total Tracking Laser™ system uses twin laser-sensing ports with front and rear detection diodes which capture diffused energy far outside the main laser beam. This provides the radar detector with superior off-axis coverage and the widest "field of view." You'll enjoy an improved sense of driving confidence, knowing that you have this high-performance technology on your side.

The BEL 946 uses VG-2 Guard to shut down the unit when it detects the presence of an operating VG-2 unit (radar detector detector). BEL radar detectors also detect radar signals used as part of the Safety Warning System. Safety radar is used to alert drivers to changing or potentially hazardous road conditions such as highway construction or maintenance. If safety radar is in use in your area, you'll be able to distinguish it from radar signals used for speed detection.

  • detects X, K, and Ka radar with separate audio and visual alerts for each band
  • Total Tracking Laser™ technology for laser detection (separate audio alert for laser)
  • VG-2 Guard™ hides the unit from radar detector detectors
  • runs on two AA alkaline batteries (included) with life of approximately 40-70 hours (low-battery warning system lets you know when 2-4 hours of battery life remain)
  • cordless operation; can be powered by a cigarette lighter adapter (not included) for corded operation
  • detects safety radar and provides alerts to potential road hazards
  • automatic or manual muting for all audio alerts silences the detector during extended encounters with radar
  • separate audio and visual alerts for laser
  • a number display flashes from 1 to 4 to confirm radar strength
  • automatic shut-off (with visual and audio alerts) when no signals are detected after an hour
  • dim/dark modes for stealth operation at night
  • city/highway modes let you reduce the false alarms caused by X band radar in urban or commercial areas without sacrificing sensitivity for detection of K and Ka bands
  • memory retention for preferred volume, audio, and city/highway settings
  • pocket reflector and earphone speaker supplied for motorcycle use (Note: the detector is not water-resistant.)
  • includes soft carry pouch, brackets for visor or windshield mounting plus Velcro™ fasteners for dash mounting
