406 Local Emergency Receiver

The 406 Local Emergency Receiver is a highly effective 406 beacon decoder/receiver.

Using the selective decode technology, new systems can be developed using powerful 406 beacons to instantly provide a distress alert when activating the beacon.

The receiver can determine GPS location and signal strength of beacons and transmit a display of this information.

406 Local Emergency Receiver Features

  • Provides a locally managed rescue
  • Ability to record or manage a “selective” group of PLB’s, ELT’s 
  • Immediate alarm (Audible & visual or e-mail notification)
  • Nearly immediate GPS coordinates
  • Available in a PC based application or integrated in a NMEA plotter
  • Direct option over a conventional 406 receiver

406 Local Emergency Receiver Applications

Marine Local Rescue

  • Marine Locally Managed Rescue System, Lost Diver,  SAR, Passenger Vessel Monitoring, Port Management, Yacht Management
  • Coastal Monitoring of PLB’s, National Parks, Extreme Recreation Monitoring
  • Search & Rescue (SAR)


The 406 Local Emergency Receiver can display an emergency beacon on any NMEA compatible display such as a GPS or chartplotter. Beacon locations can also be viewed on various mapping systems when using the PC application including Google Maps and others.

The Micro Technologies' patent pending selective decode feature allows a database to be within the decoder. This means that the decoder will only activate the alert output when a 406 transmission has been received by beacons with the matching a unique ID.

In many cases immediate assistance can be provided without the need to notify search and rescue.

406 Decoder PC Application

When connected to the supporting 406 Decoder PC application, remote real-time notification of 406 transmissions is possible. The 406 Decoder application provides visual and audible alerts of 406 distress transmissions.

When a beacon certificate number has been decoded, the beacon model and manufacturer is displayed to avoid confusion of which beacon is being read.
