Product information:

  • The MT603FG is the most advanced MEOSAR-ready 406MHz digital EPIRB on the market today.
  • Designed, engineered and manufactured in Australia, the MT603FG has obtained international Cospas-Sarsat approval.
  • Boasting the latest advances in emergency beacon technology, the MT603FG ensures the safety of your vessel and crew in emergency situations, regardless of your location.
  • The MT603FG is a Category 1 EPIRB, which means the unit will automatically deploy from the supplied ‘Float-Free’ housing via a hydrostatic release unit at a depth of 1.5 – 4 metres, with the beacon activating upon contact with water.
  • The EPIRB may also be manually removed from the housing and activated by the user.
  • The MT603FG features an integrated 66 channel GPS receiver, delivering greater position accuracy and faster location fix than previous models.
  • Boasting zero warm-up digital technology, the MT603FG acquires and transmits 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 121.5MHz VHF homing transmitter, the MT603FG is the ultimate in emergency beacon technology.
