  • Specification

LRAS1830  Long Range Acoustic Hailing Intense Sound Speaker is a compact and portable long range directional acoustic wave transmitter, far superior to other PA systems in public places, and can be used on small ships, remote control weapon stations and armored vehicles, easy for transportation. Also, it can be used by security personnel to call and warn the target at a great distance, ensuring that the verbal message can be clearly heard and understood. Acting as a non-lethal deterrent, the warning sound can help
