We include at no charge a reprogramming service on this alternative listing for the country of your choice. Registering your EPIRB is mandatory 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 & emergency contact details. 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 and Rescue services. Deliberate misuse of the device could result in a penalty.
