The Global Leader in Long Range Acoustic Hailing Devices


Compact, Long Range Communication
for Air, Ground & Sea


The LRAD 500X is compact, lightweight and designed for applications ranging from fixed security installations to mid-sized vehicles and vessels. Easily mounted and transported to provide law enforcement, homeland security and defense personnel a highly effective communication, hailing and warning capability, the LRAD 500X has been selected as the U.S. Navy and U.S. Army’s acoustic hailing device (AHD) for small vessels and vehicles.

The LRAD 500X broadcasts clear, authoritative voice commands and attention-commanding deterrent tones to safely modify behavior, enhance response capabilities and provide additional time to escalate the use of force if necessary.

The extended frequency range of the LRAD 500X ensures broadcasts are heard and understood over wind, engine and background noise.

  1. Rugged, military tested construction
  2. Low power requirements
  3. All-weather use
  4. Scalable, lightweight & portable
  5. Simple to operate – Increased coverage with single operator
  6. Safer alternative to non-lethal deterrent measures
    • Highly intelligible communication up to 2,000 meters
    • Safely communicates beyond stand-off distances to determine intent
    • Variable beam width for extended coverage
    • Clear, long-range, directional communication
    • Creates instant acoustic standoff perimeter
