Why have an EPIRB?

An EPIRB can save your life and the lives of others on board by providing rescue authorities your precise location in the event of an emergency. GME EPIRBs are self-contained 406 MHz radio transmitters that emit an internationally recognised distress signal on the Cospas-Sarsat satellite system. The MT603 series of EPIRBs contain a unique identification number which can be cross referenced to a database of registered 406 MHz beacons, allowing the beacon’s owner and vessel to be immediately identified in the event of an emergency.* 


GPS Equipped

The MT603 series of EPIRBs feature an integrated 66 channel GPS receiver, delivering greater position accuracy and faster location fix than previous models. Boasting zero warm-up digital technology, MT603 series EPIRBs acquire and transmit accurate latitude/ longitude and personal identification information to rescue authorities as soon as possible. In combination with a high-intensity, solid state strobe light and auxiliary 121.5 MHz VHF homing transmitter, the MT603 series is the ultimate in emergency beacon technology.


Water Activation

The MT603 series of EPIRBs are able to be activated both manually and automatically upon contact with water. The Category 2 EPIRB model (MT603G) will automatically activate when the unit is removed from the mounting bracket and is deployed in water by the user. The Category 1 EPIRB model (MT603FG) will automatically deploy from the ‘Float-Free’ housing via a hydrostatic release unit at a depth of 1.5 – 4 metres, with the beacon activating upon contact with water.

How do EPIRBs work?

Cospas-Sarsat Satellite System diagram

  1. A distress beacon is activated.
  2. Its signal, with its unique identification number or HEX ID, is transmitted and detected by the nearest satellite.
  3. An alert is sent to the nearest local user terminal (LUT).
  4. The alert is processed by the nearest mission control centre (MCC) and forwarded to the rescue coordination centre (RCC).
  5. The RCC is notified and begins to arrange search and rescue operation. Registration details are provided to the RCC in the country in which the beacon is both activated and registered.
  6. Search and rescue authorities commence search operations as soon as they can. If your beacon is registered with the local maritime authority, Search and Rescue will ring your emergency contacts immediately for information regarding your whereabouts. It is important to keep your contact details updated in order for search operations to commence as soon as possible.

Note: Do not turn off your distress beacon until advised by rescue services.
