McMurdo’s SmartFind G8 AIS EPIRB is the world's first Emergency Position Indicating Radio Beacon to feature AIS. This device is a Category 2 EPIRB that will alert authorities that a rescue is required, once it has been manually deployed or activated in contact with water.

In an emergency, the SmartFind G8 EPIRB draws from multiple satellite constellations, to relay a coded message on the 406 MHz distress frequency, monitored by the Cospas-Sarsat satellite system. This alert is sent to the nearest Rescue Coordination Centre (RCC) and provides a pinpoint accurate location for all authorities at sea.

The SmartFind G8, with a 10-year battery life, is an ideal long-term subscription free solution, that is excellent value for money.

McMurdo SmartFind G8 AIS EPIRB Key Features:

GPS Transmission

Upon initiation of a distress call, the McMurdo SmartFind built-in GPS will fix your position to within a few meters and then utilizes a powerful 406 MHz signal to relay your distress call to orbiting satellites. When triggered, broadcast a unique registered distress signal that not only tells rescuers where you are, but who you are. T

An additional feature is the 121.5 MHz secondary homing transmitter which means that once Search and Rescue teams have been deployed, they are able to home in on your exact location. 

AIS Transmission

In addition to GPS transmission, the McMurdo SmartFind has an AIS capability to send distress alerts to nearby AIS equipped vessels for an increased chance at a fast rescue.

Strobe Light

This McMurdo EPIRB has a high brightness flashing LED strobe light to enhance visibility in low light environments or night rescues. 

Battery Life

The McMurdo G8 SmartFind AIS EPIRB has a storage battery life of up to 10 years! Upon activation, the McMurdo SmartFind EPIRB will operate for a minimum of 48 hours. 


It is necessary to self-test your McMurdo EPIRB to ensure that the beacon functions correctly. The G8 SmartFind EPIRB offers a comprehensive self test facility with battery use indicator.


The McMurdo SmartFind G8 (Automatic) can be activated when in contact with water as well as when a manual release bracket is deployed, in the event of an emergency, to provide authorities at sea with a precise pinpoint location to send to rescue co-ordination centres (RCC) and nearby AIS equipped vessels.


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 PLBs and EPIRBs sold by OSC 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 UK.

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.
