Long Range Acoustic Device LRAD-L4000 are used for safety and security purposes in areas of higher risk of piracy e.g. Gulf of Aden/Indian Ocean.
If your shipping operation enters areas of increased risk of piracy and you are looking for safety and security equipment to add to your existing security measures, the Max 1 to 9 range of Long Range Acoustic Device LRAD-L4000 may be something to consider.
These LRAD devices are currently in use with the US Navy, as a part of a range of non-lethal measures protecting their vessels against attack.
Long Range Acoustic Device LRAD-L4000 are widely used by shipping and private maritime security companies to protect vessels against piracy and similar acts of robbery and theft at sea, with well documented reports of their useage, available on the internet.
Different from other similar products, the Max range provide fully certified environmental proofing (to US Military specifications), as well as safety features unavailable on products from other manufacturers.
All products can be permanently mounted or can be maintained in watertight cases awaiting deployment prior to entering an area of higher piracy risk.
Security can be increased by the addition of a high intensity lighting unit that can strobe or temporarily blind those it is directed at, thus attacking 2 senses (sound and light).
We are happy to respond to any queries and to recommend the most appropriate equipment for your vessel.
