The Global Maritime Distress and Safety System (GMDSS) compliant
MT403FF and MT403FG is a "state of the art" satellite distress beacon designed to operate in conjunction with the COSPAS-SARSAT International Satellite Search and Rescue System.

Designed to meet the most demanding regulatory approvals the GME MT403FF is a Class 2, Category 1 EPIRB in a fully enclosed float free housing with a Hammar HRU that will release and activate the beacon automatically on immersion in water.

Using the same innovative technology that produced and revolutionized the EPIRB world, the MT403FF now offers commercial vessel operators the same GME performance and value enjoyed by recreational boaters. A key feature of the MT403 series is the use of non-hazardous battery packs that are IATA compliant and allow for restriction free transportation.

The MT403FG has an additional 16 Channel parallel GPS receiver with top mounted Quad helix antenna to improve location accuracy to better than 100 meters typically.

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 MT403FF to enable suitably equipped Search and Rescue forces to home in on the distress beacon.

GME has been designing and manufacturing EPIRB's for over 30 years, in that time literally hundreds of lives have been saved in Australia and around the world.
