Registering your EPIRB is required by law in most countries. Registering is very important because should your beacon ever be activated, it is how Search and Rescue Teams will know who you are, and contacts provided may be able to supply information about your specific travel plans. In the absence of this information, it may take longer for a search-and-rescue operation to begin.

Some national authorities require a completed registration application form to be submitted by letter or fax, others offer an online registration. For more information, visit the emergency beacon registration database IBRD at and also The addresses of the national authorities are listed on these sites.

This EPIRB should only be used in situations of grave and imminent danger to life. False alerts endanger lives and cause expensive disruption to Search & Rescue services. Deliberate misuse of the device could result in a penalty.

Once the emergency button is pressed on your beacon, your location will be sent to a rescue coordination centre via satellite. This SOS is then diverted to emergency services near to your location to aid rescue. The location will be continuously sent for a minimum of 24 hours.


A 406MHz beacon enables the Search and Rescue agencies to quickly and accurately identify and locate an individual so that they can effect a successful rescue.
