More Australian rescues start with GME than with any other brand

GME MT403 series EPIRBs are a culmination of years of extensive R & D by GME engineers. The end result is a radical new design concept that is not only a significant improvement on existing beacon performance, but dramatically slashes the cost of 406 MHz EPIRB ownership.

The GME MT403 406 MHz digital EPIRB is the latest exciting extension of GME's growing family of innovative safety products.

The MT403 also includes a water activation feature. Once it has been removed from its mounting bracket, the MT403 will activate automatically on immersion in water. Of course you can also activate it manually if required.

Advantages of a 406 MHZ EPIRB over the older analogue EPIRBs include, worldwide coverage, position location accuracy to within 5 kms and a more stable transmitted signal resulting in faster response time. Most importantly, the addition of a unique digitally coded message provides Search and Rescue authorities with vital information including the country of beacon registration and identification of the vessel in distress, thus greatly reducing the incidence of false alerts and unnecessary deployment of valuable rescue resources.

An auxiliary homing transmitter is included in the MT403 to enable suitably equipped Search and Rescue vessels to home in on the distress beacon.
