SmartFind G8 AIS EPIRB is the world's first EPIRB to feature AIS. This a Category 2 EPIRB meaning that once manually removed from it's bracket, the device will alert authorities that rescue is required.  The G8 EPIRB gives greater location accuracy by receiving GNSS coordinates from multiple satellite constellations.  AIS capability also allows the device to send distress alerts to nearby AIS equipped vessels for an increased chance at a fast rescue.

When the SmartFind G8 is activated it transmits a coded message on the 406 MHz distress frequency which is monitored by the Cospas-Sarsat satellite system. The alert is then relayed via an earth station to the nearest Rescue Coordination Centre (RCC). With an EPIRB you can summon help wherever you are on the planet, subscription free, no matter how remote!

SmartFind G8 comes with a manual release bracket and features a self-test feature to give you peace of mind before setting off that your EPIRB is working. The 10 year battery life provides a long term solution and excellent value for money.

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.

All PLB’s and EPIRBs sold by Orbital Satcom are pre-programmed with the US country code. Whilst they will function anywhere around the world, the initial point of contact during an emergency situation would be the US Search & Rescue authorities with whom the device would be registered. Please contact us if you wish to have your EPIRB shipped with configuration for use in a country other than US.

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.
